How to Use a File Server to Share and Protect Files

Imagine a situation where you have processed enormous amount of data which is stored on your local hard drive and at the end of the day you find that this hard drive has crashed or that a virus has corrupted your file or the file accidentally got deleted and you have lost all your data. Scary, isn�t it? Such loss of data may be disastrous for the company in terms of operating consequences. It will result in loss of revenue, negative publicity resulting in brand damage and loss of reputation. Backing up your data is a solution to this problem and this is where file servers comes into the picture.

File servers can be defined as dedicated computers, which help in storing files in centralized location and allow it to be shared among the users in a network environment. File servers are designed to perform two important functions file sharing and file protection (backup). Files stored on the file server can be easily shared with other computers on the network making it a safe location to store data. Also the files on the file server itself can be backed up, ensuring further protection of your data.

Why get a file server?

A)A file server helps in regular backing up of all files stored into it. So whenever a file gets deleted or is misplaced from your PC, this file can be retrieved. Also if there is a hard disk failure the files saved on the network will not be affected.

B)The files stored on the file server can be accessed directly by each person on the network; this allows them to directly work on the document if required.

C)File server allows you to put restrictions on the file access. This means that each user on a network can be given different access rights to stored information.

The above benefits have encouraged many small and large businesses to switch to using file servers.

How to choose the right File Server for my network?

The following parameters play an important role in the choice of the right File server:

Size:
The size of the server is important as you need to fix a place where you will be keeping it. As your business grows the data volumes will increase hence you need to buy a server that will serve your future requirements. The server you choose must have enough space for adding additional hard drives and other access points.

Compatibility:
The server you choose needs to be compatible with the existing systems you use such as Windows, Linux or Mac.

Storage:
Storage is one of the most important parameters to consider when choosing the right file server. This is because the file server is going to be used to store files and keep a back up of these files. More the storage space, more the data can be stored. In a 50 user environment if the server is going to be used for keeping a back up of all user files that includes documents and e-mails, you need to find out how much disk space the data on each individual PC is taking. If 50 users need to store 2 GB of files then the total space required is 100 GB. You will need to double this capacity to 200 GB as the base capacity for an increase in the volume of data which you are expecting over a period of time.

Usability:
The interface of the file server should allow easy setting up of user, folders and security privileges.

Type of Business Application:
Depending upon the size, a network may require a Low End or High End File Servers.

1) Low end file servers: Low end file servers are suited for small businesses. They generally have a single processor and support about 500 users in a networked environment. These servers are generally smaller in size and offer low expandability which means that the server does not allow you to add extra components such as hard drives, memory component and processors. This results in limited storage capacity for such servers.

2) High end file servers: High end file servers are generally useful for large business houses and data centers with more than 500 users which does a lot of high end data processing work. The servers are generally larger in size as they have enough room to support additional hard drives and other components which would help them to enhance their performance. These servers are used for data intensive applications and since speed becomes a very important criterion, these servers support more than 1 processor. Low end file servers have internal fans and cooling mechanisms, but high end file servers in data centers generate enormous amount of heat and need to be kept in specialized server room with controlled environmental conditions.

Now, that you are aware of the benefits of getting a file server and have an insight into the parameters that should be looked into while buying one, the decision to get a fileserver need not be further delayed. Should it?

How To Install a Scanner

Introduction

Congratulations on getting a new scanner! You can now convert your original documents and printed images into digitized form for editing and processing on the computer. The software program included with your scanner will help you do this.

Whenever you buy a scanner it comes bundled with the required software. This bundle may contain driver program, image-editing software, color calibration software and optical recognition software (OCR). TWAIN is one of the driver programs used by most of the scanners. This program performs the actual scanning operation. The TWAIN driver allows image-editing and facilitates the optical character recognition software to control the scanner and get the scanned output of the image or a document with the scanning program requiring it to be saved.

Installing a scanner is not a difficult task. However, the procedure will vary depending on the type of scanner you choose. Scanners are available with three types of interfaces. They are as follows:

Parallel port

SCSI (Small Computer System Interface)

USB (Universal Serial Bus)

Parallel Port

Parallel port scanners connect to the computer via the parallel port. They are the cheapest of the scanners. They are however slower than scanners with other types of interfaces. A scanner with parallel port interface communicates at a rate of 1.2Mbps with a PC. The procedure for installing a parallel port scanner is a very simple. But remember that when you install a parallel port scanner, you won't be able to use your printer and your scanner at the same time.

The steps to install a parallel port scanner are as follows:

Step 1

Shut down your PC. Place the scanner close to the PC on a flat surface. The cable of the scanner must be able to reach your computer.

Step 2

Disconnect the parallel cable of the printer from the parallel port on the back of your PC.

Step 3

Attach the parallel cable of the scanner into the port where the printer's cable was attached. The 25-pin female end of the parallel cable is connected to the PC and then other end of the cable plugs into the scanner's port. For using the printer as well as the scanner, connect the printer cable to the scanner and then connect the scanner to the PC.

Step 4

Insert the power cord of the scanner into an outlet. Once you plug in the power cord, the scanner starts by itself. Some scanners will require manual intervention for turning them on. If your scanner has an on/off switch, switch it on once you plug in the power cord.

Step 5

Turn on your PC. The Operating System (OS) installed in your PC will automatically recognize the new hardware that has been added. If your OS does not recognize the new hardware, Click on Start >> Settings >> Control Panel . Double click on the Add New Hardware option. A new wizard will appear that will guide you through the installation process.

Step 6

The installation wizard at some point will ask you to install the driver disk that has all the required information files. Insert the driver disk at the appropriate time, and then choose the device's .INF (Information) file from the disk to have all the information properly installed. During this process you may also install TWAIN driver.

Step 7

You may also install all other additional software�s that you may have received with your scanner. It is advisable to calibrate the scanner before you start using it. The color calibration software tries to maintain the original colors of the image throughout its processing. This means that what you see on the monitor and what you print out should be reasonably close to the colors of the original.

SCSI (Small Computer System Interface)

The SCSI interface offers performance, expandability and compatibility that is unmatched by any other current PC interface. A SCSI interface offers much faster transfer rates and takes up few resources from the computer's CPU. However, a SCSI interface is expensive and a scanner with a SCSI interface will cost more. If your scanner does not come with a SCSI card, you will have to buy one separately. Also you will require a SCSI slot on the motherboard for the SCSI card.

The steps to install a SCSI scanner are as follows:

Step 1

Turn off your PC and unplug the power cord from the power outlet.

Step 2

Open the computer case and look for a slot of the same type as the SCSI card. Most SCSI cards shipped with scanners are called �ISA� cards. These cards fit in the slot with two connectors. Remove the screw that holds the slot cover and slide your SCSI card in the slot. Place the connector in line with the slot and push it in place. When the card is firmly seated, secure the card to the motherboard using the screw. If you are adding a scanner to the PC that already has a SCSI card in use, you will have to attach the scanner to the end of the devices that make use of the SCSI interface.

Step 3

Insert the power cord of the scanner into an outlet. Once you plug in the power cord, the scanner starts by itself. Some scanners will require manual intervention for turning them on. If your scanner has an on/off switch, switch it on once you plug in the power cord.

Step 4

Turn on the PC. The Operating System (OS) installed in your PC will automatically recognize the new SCSI card that has been added. If your OS does not recognize the new hardware, Click on Start >> Settings >> Control Panel . Double click on the Add New Hardware option. A new wizard will appear that will guide you through the installation process.

Step 5

Once the SCSI card is detected by the OS, insert the driver disks as directed by the installation wizard to complete the installation. During this process you may also install TWAIN driver.

Step 6

You may also install any additional software that has come with your scanner. It is advisable to calibrate the scanner before you start using it. The color calibration software tries to maintain the original colors of the image throughout its processing. This means that what you see on the monitor and what you print out should be reasonably close to the colors of the original.

USB (Universal Serial Bus)

The USB scanner is the best choice as the Universal Serial Bus (USB) interface supports faster data transfer rates of upto 12 Mbps. A single USB port can be used to connect at least 127 peripheral devices and is ten times faster than a serial port. USB also supports Plug-and-Play installation and hot plugging. The USB interface is easy to use and this makes installation of USB scanners very easy.

The steps to install a USB scanner are as follows:

Step 1

Exit all the programs currently running on your PC.

Step 2

Plug in the scanner into the USB port of your PC.

Step 3

The Operating System (OS) installed in your PC will automatically recognize the new interface that has been added. If your OS does not recognize the new hardware, Click on Start >> Settings >> Control Panel >>. Double click on the Add New Hardware option. A new wizard will appear that will guide you through the installation process.

Step 4

The installation wizard at some point will ask you to install the driver disk that has all the required information files. Insert the driver disk at the appropriate time, and then choose the device's .INF (Information) file from the disk to have all the information properly installed. During this process you may also install TWAIN driver

Step 5

You may also install any additional software that has come with your scanner. It is advisable to calibrate the scanner before you start using it. The color calibration software tries to maintain the original colors of the image throughout its processing. This means that what you see on the monitor and what you print out should be reasonably close to the colors of the original.

The other additional software that may be available with the scanner or which may be purchased are the image editing software�s and the Optical Recognition Software (OCR) software. The image editing software such as Adobe PhotoDeluxe and Adobe Photoshop help in manipulating color, grayscale and line art pictures. The Optical Recognition Software (OCR) is necessary to produce an editable text format from a scanned document. Optical recognition software examines the scanned image and converts it into a format that can be read by a word processor, spreadsheet or database.

Conclusion

To summarize, whatever may be the interface of your scanner, following the steps mentioned in this guide will make the installation process a simple and easy task.

Antivirus Software Buyers Guide: Protecting Your Computer

Introduction

Everyday there are new security threats emerging from viruses to phishing, from spyware to denial-of-service attacks, from Trojan horse to worms or several other forms of malware. Viruses, worms, and the like often perform malicious acts, such as deleting files, accessing personal data, or using your computer to attack other computers. It�s devastating to lose all the data on the computer, and proper precautions need to be taken to avoid such a situation. An Antivirus is a software programme which protects the computer against possible infection by viruses or other malicious software. Antivirus software consists of a scanning engine, which sieves through all the files on the computer to detect the presence of a virus.

Antivirus softwares have come a long way from just protecting the computer against viruses. The latest trend in the antivirus market is online virus detection. The antivirus manufacturer remotely scans the computer via the browser, when on the manufacturer�s homepage; thus curtailing the need to install antivirus software. Few of the popular ISP�s offers online scanning facility as part of service pack. Most of the email service providers offer high-tech antivirus solutions such as automatic scanning for all the attachments received with emails. Few antivirus softwares, supervise the system files which are accessed to check if they have been manipulated in suspicious manner. This functionality helps detecting and removing the virus even before they are detected by the virus definitions.

There are known viruses which have certain characteristics and behavioral pattern; Antiviruses utilizes heuristics to detect any suspicious activities or patterns by new malware based on similarities with the known ones. The Antivirus software buying guide aims to assist through the process of choosing an antivirus solution, by helping to make a well informed decision.

Norton AntiVirus 2008

CA Anti-Virus 2008

Features

1) Regular Updates:
New viruses are getting released every day, due to which regular virus definition updates are required. It functions on the similar principle as the �Interpol�s most wanted list� of people who needs to be caught; in order to identify the latest threats on the computer, virus definitions are developed by antivirus companies to inform and update their subscribers. Opting for an antivirus which consists of an automatic update tool is a sensible decision. Some software includes features such as scheduled updating for the latest virus definitions, on a regular basis.

2) Firewall:
Software firewalls keep inside information from leaking outside onto the Internet. A firewall has a built-in filter that forbids any unauthorized or potentially hazardous material from entering the system. Webmaster defines internal access policies for the server.

3) Internet Security Suite:
Internet security suite allows one to browse the internet threat-free. It offers essential protection from viruses, hackers, privacy threats, and transfer of confidential information such as passwords or credit card numbers.

4) Antispyware:
Resistance against viruses is provided via antivirus software. Similarly Antispyware programs helps detection and removal of any spyware or unwanted element from the system and immunes the system. Some of the antivirus softwares facilitate fortification against both viruses and additional features such as ability to discover and eradicate spyware are included in such antivirus software. Anti-spyware softwares must be installed on every computer and it should be regularly updated. With the spyware�s ability to reproduce itself, this is an important feature; although dedicated anti-spyware programmes are also obtainable.

5) Easy to Use:
Software interface of the antivirus must consist of simple to use utilities and features; which would enable the user to install and configure it without any help. Always read the review of the softwares to check the user ratings before investing. There is functionality in few antiviruses which, provides warning to the user when any program attempts to modify the critical areas on the system such as Registry. For that reason it is recommended to turn off the functionality before installing any new software on the system.

6) Technical Support & Availability:
Incompatible driver issues or conflicts with other installed applications are very frequently arising problems with the system. Whenever such issues arise, one must be able to get quick assistance from technical support. Best option is choose the company that provides free phone support during the trial period of software and free technical support via chat or e-mail as most of the companies charge for phone support.

7) Subscription & Renewal Fees:
Antivirus software like AVG and anti-spyware programmes such as Spybot are available for free for users to download and use. Most of the software utilities are priced on per license basis. Whereas some come with annual fees subscription for updated antivirus signature files to block the newest threats. Antivirus softwares used for professionally are usually available on annual subscription fees basis. Any antivirus software is up-to-dated only due to regular virus definitions, outdated antivirus software equals to ineffective one.

8) Email Protection & Attachment Scan:
The profusion of e-mail worms has increased the need for antivirus which offers e-mail protection. Most of the antivirus softwares nowadays offer email security by implementing e-mail security options. These options consists encryption of data, virus protection via incoming email, spam filtering, and attachment scanning for potential threats.

9) IM Protection:
Instant messaging has become one of the main reasons for users to get online. It is advisable to opt for antivirus software offering IM protection. It means that IM will have the same kind of protection as email support. This will guard the computer against accidental virus transmit or malicious efforts to gain remote access on the computer via a Trojan or backdoor application.

10) Real Time Protection:
Many antivirus software enable real-time protection on the system to prevent known installation unwanted programs such as virus, Trojans, worms and spyware. Real-time protection maintains a constant vigilance on the critical checkpoints of the system. The checkpoints are triggered when unknown programs try gaining access on the system or make changes to windows configuration. The real-time protection alerts the user, immediately when a change is detected on the system; probing the user to allow or deny the changes being made. Real-time protection scans the incoming network data and disk files at download time, and blocks the activity of components known to represent spyware. In some cases, it may also intercept attempts to install start-up items or to modify browser settings. Real time protection can slow down the computer as it scans the computer live in background.

Conclusion :

There are a number of antivirus applications offered by different software vendors, and each application has its own set of extra features. An individual using a single computer has different needs than a family that shares one or more computers. Arrays of computers on a LAN require a different level of antivirus protection than a single desktop. Possibilities of virus attacks and other security breaches require through consideration and a comparison needs to be done on the basis of the features available, keeping in mind the overall outlook.

How to Secure Your Laptop�s Data

The one feature which has made users choose a laptop over a desktop, for personal computing, is mobility. But this mobility has its drawbacks. Carrying a laptop from one place to another is risky. There is a possibility of your laptop getting stolen and sensitive information present in your laptop being misused. To ensure that this does not happen to your laptop it is essential that you secure it.

How does one secure a laptop?

You can secure your laptop using security measures using physical devices such as tag and docking station; or by installing software which prevent or alert about theft. You could also install softwares which prevent unauthorized access to your laptop thereby enhancing its security. These and other measures to ensure the security of your laptop are explained in detail in the following section.

Tagging:

Tag your laptop or mark the outer case with the personal or company details such as address, phone and name of the company that will help you in getting the laptop back if you misplace it while on the move.

Docking station:

In your office you can use a docking station to protect your notebook from theft. A docking station is a part of the notebook that remains on the desk and has extra connections for bays, slots and a feature that locks the laptop in one place.

Notebook Tracking Software:

Installing Softwares such as ComputraceComplete and ComputracePlus developed by Absolute Software Corporation will enable you to monitor who is using your laptop, what changes are made to your hardware and software and where the laptop presently is. Such softwares not only help protect your laptop, but also help you to recover them. If a person who has stolen the laptop were to connects to the internet, the laptop starts communicating and sends alerts the Absolute Monitoring Centre, which captures the IP address of the laptop is using to log on to the internet. The internet service providers can then try to find the laptop.

Registration:

Registration of lap top with the manufacturer, at the time of purchase, could prove helpful in case of theft. If the stolen laptop is sent to the manufacturer for maintenance, the manufacturer can easily trace the original buyer of a registered laptop and return it.

Installation of Security Software:

You must install a security software suite which includes a virus scanner, a personal firewall and antispyware software. Personal firewall such as Zone Alarm, Norton Internet Security and BlackIce will protect the laptop from viruses which may try to gain entry through the internet. If you are using the Windows XP operating system then you should disable the file and print sharing option in the network connections control panel and use the latest Windows XP patches by enabling the automatic updates in Start > Programs > Windows Update.

Operating Systems which control access:

Select a secure operating system such as Windows XP Professional or Windows 2000 Professional. These two operating systems offer a secure logon i.e. if you are not going to use your laptop for sometime then you can lock your laptop. To lock your laptop Press Ctrl + Alt + Delete on your keyboard. You will get a dialog box with various options. Select Lock Computer. This locks your laptop. Now no one will be able to use your laptop until and unless you unlock it by inserting your password. Windows XP Professional or Windows 2000 Professional also offer security at file level and are able to encrypt your data. If you are using Windows 95/98/ME operating system, then anyone can access your laptop data.

Biometrics:

Nowadays it has become very easy to crack a password. This has made some manufacturers provide their laptops with fingerprint identification software�s, which recognize user�s fingerprints as logon ID instead of a user entered password. These software�s are called as biometric identification systems. Biometric identification is the process of identifying individuals by means of certain physical characteristics such as fingerprints, eye structure and voice. When the software is first run on a users laptop his fingerprints are stored in the laptop, every time a user then tries to login the software authenticates users based on their fingerprints. The use of fingerprint identification software�s makes it tough for a burglar to access sensitive data on a stolen laptop because if the software is not able to identify the correct user, it will prevent the laptop from booting. E.g. Targus PA461U Defcon Authenticator

Setting up BIOS password:

You need to set up a strong BIOS (Basic Input/Output System) password for your laptop. The BIOS is an in-built software that controls the basic operations and is responsible for starting the computer up and initializing the hardware. You need to know from the manufacturer how to change the BIOS password. You also need to find out whether the BIOS password is capable of locking the hard drive so that if the hardware is removed and reinstalled in another laptop nobody will be able to access the data.

Creating a Virtual Drive:

Today software�s are available in the market that provides encryption for your notebook. These types of software allow you to create a virtual drive on your existing hard drive where you can store company�s secret information in encrypted format which only you can access them. For E.g. SafeHouse Software

Protecting portable notebook component:

Protecting the portable components of a notebook is another challenge. You need to protect your laptops components such as NIC card, flash drives or modem that remains outside your laptop. Though flash drives are less expensive they are capable of storing lots of data. You need to use flash drives that require a password or finger print to access it. E.g. Lexar JumpDrive Secure II USB Flash Drives.

Neglecting Laptop security can turn out to be a costly mistake. Always take adequate security measures to protect your laptop and its data.

Surge Suppressor Buyers Guide: Protecting Your equipment

Introduction

An unexpected burst in power can damage the computer, office automation products or anything with internal electronic circuits. A lot of thinking and investment is done before buying such appliances, and it is equally important to safeguard these appliances from damaging power surges or spikes.

1) Need For Surge Suppressors:

Even the smallest surge or spike can demolish or affect the performance of costly electronic equipment, thus creating need for surge suppression. Equipments such as computers, phones, faxes, TVs, VCRs, gaming consoles, stereos and microwaves can be damaged instantly or over a period of time due to minor surges which cause plodding deterioration of internal circuitry. The necessity for surge suppressors has now become greater than before due to the extensive use of microprocessor chips which are highly sensitive to voltage variations. Surge suppressors generally come in a "strip" or box form; they have several power outlets for appliances to be plugged into.

2) Surges and Spikes:

Surges and spikes are the sudden increase of energy that exceeds the voltage and amperage capacity of the equipment, causing damage to the equipment if not suppressed. These are usually caused by a sudden change or demand for additional power, such as turning on a large appliance such as an air conditioner.

A surge is a small transitory wave of power in an electrical circuit. It characteristically measures less than 500V and lasts less than two seconds.

A spike engages an abrupt noticeable jump in voltage; much shorter in duration when compared with a surge. It�s less than one-thousandth of a second (millisecond), but could be measured into thousands of volts.

A spike or a surge can damage an electronic device beyond repair. Lightning and daily electric service switching and maintenance could also produce damaging electrical surges on the energy source.

Tripp Lite Protect It! TLP602 Surge suppressor

APC SurgeArrest Home/Office Surge Suppressor

3) How Surge Suppressors Works:

Power surges and voltage spikes could damage electrical appliances; surge protectors are designed to protect the appliances from them. Surge protectors make an effort to standardize the power supply to electric appliances by jamming or shorting to ground voltage above a safe threshold. The extra voltage is diverted in most of the surge suppressors, by a component called a metal oxide varistor.

4) Choosing the correct Surge Suppressor:

Whilst investing in a surge suppressor, it is recommended that the following features are to be considered:

3-Line protection:

Surges could usually take place between hot, neutral and ground lines; thus selecting a unit that provides protection along all three lines is advisable.

UL 1449 clamping voltage:

It is highly recommended to get a surge suppressor whose clamp voltage has been rated by Underwriters Laboratories (UL). Lower the ratings better the protection. 330 volts is the lowest UL rating for clamping voltage.

Ground indicator light:

Most of the surge suppressors come with indicator lights, which show that the ground line is intact to offer protection.

Indicator light:

Indicator lights display that the unit is being guarded In case the unit crosses its capacity the light goes off, indicating the unit is unguarded.

Circuit breaker:

In case a circuit is overloaded, the breaker stops the flow of electricity. It should be noted that the circuit breaker is not associated to surges or spikes.

Response time:

Response time rating indicates how fast a surge suppressor can respond. Faster is the best.

Power shut down protection:

As soon as the unit reaches it peak capacity, this feature closes off power to all outlets immediately. Power shut down feature prevents further surges and spikes from reaching linked appliances before the surge suppressor is replaced.

EMI/RFI:

Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) are generated by the propagation of electronic equipment in the surrounding environment. They are accountable for the early wear of electronic components. Whilst comparing the EMI/RFI specs, it should be remembered that wider the frequency range (kHz to MHz) and the greater the noise reduction in decibels (dB) across that frequency range, the better the filtering.

Alarm:

Alarm functionality is very important, when a unit does not feature power shut down protection or when the indicator light is out of sight. A perceptible alarm informs one of surge suppressor not being functional and needing immediate replacement.

Guarantee:

Few of the manufacturer offer data recovery program where the cost pertaining to recovery of lost data due to hard disk failure by surge will be covered by them.

Cable line, Digital satellite line & Phone line protection:

Surges and spikes can also be caused by cable lines, digital satellite lines, and phone lines. Therefore it is very necessary to protect these lines along with the power lines. To secure these lines it is recommended to use surge suppressors with specially designed digital satellite jacks, coax line jack, and phone line jack.

Conclusion:

Few of the high-end surge suppressors are offered with a Connected Equipment Warranty (CEW). If any equipment failure occurs due to surge or spike, the company will hypothetically cover the cost of replacement. It is highly recommended to read the fine print as few of them only cover the market value of the lost equipment (which is often nowhere near enough to replace it!)

Maximizing Your iPod's Battery Life

All the iPod users will agree to the fact that the iPod�s battery life running out is their biggest nightmare and maximizing the battery life is a vital concern for all the iPod owners.

Once the battery life is over the only option would be an expensive battery replacement or getting a new iPod. iPod�s battery has a lifespan of 500 to 400 charging cycles depending upon the model you have. (A charging cycle is a full discharge--that is, when the battery is completely drained of power and follows it with a full charge.)

If you utilize and recharge your iPod's battery less frequently and with care, there's a good chance the battery will outlive the hard drive. Here are the how-to steps to get the longest life possible out of your iPod�s battery.

1) Use your iPod regularly:

Batteries must be continuously used in order to keep them fresh and optimal to hold a long charge.

2) Turn off the EQ:

The equalizer function is incredible but it will utilize your precious battery life. If you want to maximize your lifetime for each charge, just turn it off.

3) Store your iPod in a cool place:

Try your best to keep the player out of heat. This will definitely affect your battery life.

4) Hibernation Mode:

If you're putting your iPod in storage for an extended period of time, i.e. more than a month or two, be sure the battery is only partially charged. Stored with a full charge, the battery will permanently lose just about 20% of its capacity per year. Even preventive measures can't put off lithium-ion batteries from losing capacity over time - but their rate of deterioration can be minimized by storing the iPod at cool (not freezing) temperatures.

5) Use Shuffle:

It's better to use shuffle option rather then selecting which song to play - the more you switch songs/surf through menu more battery power you use. Play your music by album or by playlist, rather than hopping from one track to another.

6) Update the IPod Firmware regularly:

Use the latest iPod firmware, as Apple keeps developing important battery-saving tweaks.

7) No Artwork:

Battery life for your iPod can be increased if you do not exhibit artwork (this can be set on the iPod tab of iTunes' preferences, when an iPod is attached.)

8) Don�t wait for battery to drain completely:

Charging your battery at any point of its battery stage is completely safe. Partial charging is just as effective as a full charge and will cause no harm to your system. Recharge the batteries fully at least once every three weeks to prevent the battery from going flat, however less your usage is.

9) Turn off the backlight:

Change the settings for your backlight to turn off promptly, so that it won�t utilize more battery power for lighting. You can assign the amount of time you desire the backlight to remain on (2, 5, 10, or 20 seconds). Turning the brightness all the way down can also save you masses of battery life.

10) Use AAC/MP3 file formats:

Storing the songs in AAC or MP3 formats is highly recommended (Due to it being compressed), when compared to WAVs or AIFFs formats which are uncompressed, resulting in higher file size. The uncompressed format files utilize more Cache space then compressed files, which results in more exertion on the hard drive to retrieve data.

11) Use the �Hold� button:

The "hold" button on the top of your iPod; once you slide it to the left, your iPod gets locked, and no buttons can be pushed unless and until you slide it back to the right. This would prevent the device getting accidentally turned on if something brushes against it while it is in your bag or pocket, using this function the iPod battery won�t be draining when you�re not listening to the device.

How to Protect Your Wireless Network

Wireless Networking technology has heralded an era of a networking where the workspace is free from the clutter of mangled wires and where users are no longer restricted to using fixed locations to access their network. It has provided wireless network users the mobility which wired networks can never offer. The wireless network offers invaluable convenience, comfort and support using devices such as laptops and PDAs. Despite the convenience wireless networks offers they are prone to unauthorized access if proper network security measures are not in place. For your wireless network have you given a thought to how you would secure the data in your device from malicious activities?

Always remember! A small act of negligence, on your part, in regard to security of your network can not only put you in trouble but may also lead to damaging consequences like misuse of valuable data.

Before discussing the steps for protecting your wireless network and ensuring security the device connected to it, let�s look into some of the factors that may normally degrade the security of the network and devices connected to it.

1. Using default settings for the device connected to the network
2. Networking components such as wireless router operating on default settings.
3. Not encrypting data being sent on the network

Such situations make it easy to any hacker or a wardriver, to access your unsecured wireless networking system and possibly use it for some malicious activities. Malicious activities may not be restricted to accessing/tampering your persona/confidential data, files and folders, it could also include use of your network to surfing web for illicit data, mailing obnoxious and spam messages. Does that mean that wireless networks are unsecured? Isn�t there any measure that you could proactively apply to protect your wireless network.

Indeed there is! Infact there are simple measures you can take, to protect your network becoming an easy prey for unauthorized users or hackers. Let�s look into some of them:

1. Change the Default Setting of the Wi-Fi Router

A. Change your default router access loginname and password:

Changing the default router access password and login name is the first step to ensure network security. Failure to do this makes it easy for an unauthorized user to gain access to your network. To prevent this, change your default setting once you enter the set up.

Always try to keep a login name and password that is a combination of alphabets and numbers, but not something relating to your personal information. Make it as complex as possible for others to figure it out.

B. Changing your default SSID: Another way to protect your network is to change its SSID. But what�s SSID?

In a networking environment, for communication between the wireless device and wired LAN, you require an access point. A system wherein an access point connects a wired network with wireless devices constitutes a Basic Service Set (BSS).

Data (packet) transmission between your mobile device, for e.g. laptop, and BSS utilizes a set of 32 alphanumeric characters that also act as password. This set of unique character is the Service Set Identifier (SSID) and it�s unique because it is different for different WLAN. So any device, in order to connect to a specific WLAN, must possess the same SSID.

For enhance protection, it is always advisable to change your default SSID and keep it something long, complex and of course alphanumeric. For changing your SSID refer to the owner�s guidelines.

2. Stop SSID Broadcasting:

If you still feel that changing your SSID won�t aid you in effectively protecting your network, then another methods you can opt for is to stop your SSID broadcasting. Wireless router usually has the option for turning off your SSID broadcasting. This would benefit you in a manner that any unauthorized person or a wardriver won�t be able to trace if you have a network and hence would not access your wireless network.

3. Assign Static IP Address to Devices:

If you have Dynamic Host Configuration Protocol (DHCP) then turn it off using the instructions from the manufacturer�s manual. DHCP assigns a different IP address to any device whenever it connects to the network. This poses a risk to the network as any device that falls in your networking equipment range can get a different IP address from the router and hence gets added to your network

It�s safe to assign a static IP address to each device of the wireless network device Assigning a static IP address to a device is a fairly simple process.

To assign a static IP address:

1. From the Start Menu select Run
2. Type Command and press Enter to open the command prompt window.
3. Type ipconfig/all at the command line and press Enter

The window displays the required IP address.

In order to reconfigure it, follow the following steps:

1. From the Start menu select Settings > Control Panel
2. From the Control Panel select Network Connections
3. Select device you want to configure and right click on it and select Properties
4. In the dialog box that opens, scroll to the Internet Protocol (TCP/IP)] entry and click on the Properties button.
5. Select the radio button next to "use the following IP address" and enter the IP address.

4. Enable WEP or WPA Encryption:

In a wireless network, since data transmission is through radio waves, there is a higher possibility of data interception or interference by an unauthorized user connected to the network. This process is generally referred to as eavesdropping. Encrypt your data to prevent eavesdropping. Wired Equivalent Privacy or WEP is a technology, which encrypts data being transferred using radio waves, enhancing the security of data being transmitted. Though WEP is a popular technology, drawback such as easy cracking by hackers, limits its use for securing wireless network.

The downside of WEP encryption can be overcome by using another advanced technique of Wi-Fi Protected Access or WPA. Wi-Fi Protected Access makes use of advanced technology such as Improved Temporal Key Integrity Protocol (TKIP) for improved data encryption and Extensible Authentication Protocol (EAP) for user authentication.

Although a WPA devices is being preferred over WEP devices, newer wireless networking devices can be configured with any of these encryption technique.

5.Enable Access to Your Network Based on MAC Address:

MAC here does not refer to the Macintosh it refers to Media Access Control. The MAC address is a unique set of number associated with the networking hardware, basically the network adapter. It provides a unique identification to any device in a network. By controlling a device�s access to the network based on MAC number ensures that only devices that have a MAC number configured in your wireless router can connect to your network.

You can view your MAC address using following steps:

1. From the Start Menu select Run
2. Type Command and press Enter to open the command prompt window.
3. Type ipconfig/all at the command line and press Enter

The window that opens up, displays the required MAC address.

Following simple measures such as those mentioned, go a long way in enhancing security in a wireless network. Has your network taken these measures?

Microphone Buyers Guide: Everything You Need to Know

Introduction

The word "microphone" was derived from the Greek word mikros meaning "small" and phone meaning "voice" or "sound". Microphone is an electronic device which amplifies the source sound into an electrical impulse that can be amplified and recorded. The desired sound output is achieved due to a small part in the microphone called the diaphragm. Sound outputs through the air cause the diaphragm to vibrate. These vibrations generate an electric current, which is sent out to amplifier to create sound output. There are many microphones to choose from and the important thing is to consider while choosing the correct microphone is the desired end use.

The microphone buying guide aims to assist you through the process of choosing a microphone, by helping you to make a well informed decision.

Types of Microphones and their applications

Most microphones function on these technologies; Electromagnetic generation (dynamic microphones), Capacitance change (condenser microphones) and piezoelectric generation to produce the signal from mechanical vibration. Condenser microphones require power source, whilst dynamic microphone do not. Different types of microphones operate on different sets of principles; below mentioned are the sets of principles they function on and their applications.

Dynamic Microphones:

Dynamic microphones utilize diaphragm connected to an inductive coil which is placed inside the field of a permanent magnet. Whenever the diaphragm moves, it initiates the coil, thus varying the voltage the coil generates. Dynamic microphone are economical and sturdy, and thus are commonly utilized by performance artists.

Ribbon Microphones:

Ribbon microphone are exceptionally fragile, when compared with dynamic microphones. They function on the same principle as the dynamic microphones but the diaphragm here is replaced by a thin ribbon. Ribbon microphones are very popularly used in recording studios.

Piezo Microphones:

The piezo microphones work on the concept of piezoelectricity � when subjected to pressure, some materials have the ability to generate voltage - translate vibrations - into electronic signals. These microphone are often utilized as contact microphones during live performance to amplify sound or to capture sounds in unusual surroundings.

Laser Microphones:

The core functionality of laser microphones is adopted from laser technology. A laser microphone consists of a laser beam that needs to be reflected utilizing glass or any firm surface which vibrates in understanding with close by sounds. Laser microphone works on the principle of using any vibrating surface close to source of sound to reflect the sound onto the microphone. These microphones are utilized as spying gadgets.

Condenser Microphones:

A condenser microphone contains a thin conductive diaphragm located in proximity to metal plate known as backplate, creating a capacitor. Phantom power or batteries are utilized to provide electric charge to the capacitor. The diaphragm vibrates due to the pressure from soundwaves, and results in fluctuating distance between it and the backplate, consequently generating variations in the output voltage. The microphone's signal is generated from this varied output. These types of microphones are highly recommended for laboratory and recording studio use.

Conclusion

Good old fashioned research is most certainly will help one in selecting a microphone. Any worker knows the importance of having the right tools for the right job and microphones aren�t any exception. Check the recommendations from experienced/professional microphone users. For any specific type of microphone, refer to consumer comments on some websites. The correct positioning of microphone is as significant as selecting it. To get the end results perfect it is very important to be equipped with the right knowledge. Professional compatibility, the consumer compatibility and the connectivity are three things that matter the most.

Developing and Delivering an Effective PowerPoint Presentation

Next week, you have a client visiting your company, and your boss has asked you to make a presentation on the project you are working on. Which application would you choose to make your presentation? Go for PowerPoint of course! But is selecting PowerPoint to develop your presentation enough to make sure you have a fabulous presentation? Don’t think so! A PowerPoint presentation is not just about giving a presentation; it’s something more than that. There are several other content and design factors which play a role in making your presentation effective.

The main purpose of PowerPoint presentation is to put forward your thought to the audience in an acceptable and attractive manner. The content should focus on the requirements of the audience. Hence the PowerPoint presentation should be such that it is able to grab the attention of the audience, maintain its consistency throughout and is able to convince them about your thoughts and ideas.

If the presentation, you are planning to give is business-critical then the effectiveness of your presentation would be a big deciding factor for your business growth. Here are a few tips that not only help you to make an effective PowerPoint presentation.

For making an effective PowerPoint presentation, you must decide upon three factors:

1. The content or the data you want to make use for your presentation.

2. The final layout or the design of the presentation.

3. The way you are going to deliver the presentation to the target audience

Let’s look at each of these points in detail.

Content:

Before making the presentation, you need to decide upon the base of the presentation. What information the audience is trying to seek and what output they are receiving from your presentation should form the basis for any presentation.

The easiest way is to decide on your content is to set up an outline of the content for your presentation and then order the content in a systematic manner. This not only provides you a brief layout of your presentation but also enables a quick check of your content. Going through the content you could decide whether it is as per the requirement. While doing so, remove any irrelevant information, you find not apt from the audience viewpoint.

Supplement each section of content with a suitable title. Content in each section should be placed in order of their relevance for e.g. if you are giving a presentation wherein you are addressing a business group regarding PDAs, you can first explain its features briefly followed by its merit and applications; but the point you need to emphasize more is its price range available in the market. This is the clinching factor for most people on taking the buying decision. Include appropriate pictures and figures wherever necessary to make your presentation more effective.

Once you have a rough idea about the content to be included in the presentation and its flow, next step is to design and develop the actual presentation based on this idea.

Design:

The most important factor in developing an effective presentation is its design. The design is crucial to the presentation because, it is from the design that the audience views your thoughts Design of any presentation should be impressive and attractive enough to catch hold of audience attention just in one glance. Let’s discuss some of the parameters that affect the design of PowerPoint presentation.

1. Size of the Font: The size of the font you are going to use for presentation is an important factor. It directly relates to how far the audience is from the screen and hence varies depending upon the requirement. Maintaining a consistency as regard to font size, for e.g. Titles with a specific font size, subtitles with a specific font size.

2. Type of Font: Selecting the font type is solely based on individual’s requirement. Remember data written in a particular font may look broader when you view it from very close and the same may look narrow if viewed from a greater distance.

3. Background: Keep a background that is neither too bright nor too light in color. You can maintain the background as simple as possible. You can also choose your own background and maintain the same across all slides. What’s necessary is that background should be uniform across all the slides for consistency in appearance. The text font and color should be in direct contrast to the background for easy reading.

4. Images and charts: Insert as many images as required, as it’s one of the best way of explaining and elaborating on your point to the audience. Images make it easier for the audience to grasp your explanation. Include charts or table wherever necessary, when making a comparison.

5. Animation effects: This feature is normally used to divert audience attention from you. You can choose any of the special effect available in PowerPoint to make your slide presentation visually attractive.

6. Use hyperlinks: You can also use a hyperlinks, This would enable the viewer/presenter to clicks the link and move to the relevant section of the presentation. Using hyperlinks effectively eliminates the need to move through the presentation in a specific order.

Delivery:

After you prepare a presentation, next step is how best you can deliver it in front of the audience. All efforts in making the presentation would be futile if you fail to effectively deliver it to the audience. Merely giving a presentation by reading the slides is not at all enough to make an impact on the audience. One must portray confidence while presenting your thoughts and ideas.

Certain tips you must remember for making an effective delivery of your presentation.

1. Maintain eye-contact with your audience to the extent possible, since it enables speaker to deliver presentation more effectively.

2. Always speak loudly and clearly and lay more emphasis on certain special point to create a better impact on the audience.

3. Try to rehearse before the final presentation. This would help you to eliminate unnecessary information and a quality check of your content.

4. Check the device you are making use of, to give your presentation. In case of a laptop, charge it completely before the final presentation to avoid any shutdown.

5. Avoid reference that involves internet requirement as its reliability cannot be predicted and it may lead you to embarrassing situation.

6. Check all the connections beforehand for e.g. the projector is properly connected to your laptop. After this, you can again practice for a dummy presentation in front of your colleagues and take appropriate suggestion from them. Based on their valuable feedback, you can make the necessary changes, wherever required, for overall presentation.

Now that you know how to make an effective presentation, go ahead make an impression with your client.

A Big Step Forward for AMD

The enthusiast video card landscape has been in constant flux for nearly its entire existence. For the last 6-7 years, you have seen NVIDIA and AMD constantly refreshing their respective product lineups, usually due to a combination of new technology becoming available and in response to their competitor’s advances. A lead in one sector (high end, midrange, value) typically was not long lived.

Since the release of the GeForce 8800GT, NVIDIA has had a stranglehold on the midrange enthusiast market. At the $200 price point, AMD had no cards on the market that could directly compete with the 8800GT from a cost/performance ratio. The release of the 9800GTX further solidified NVIDIA’s position as having the midrange card to beat. Around the end of June, AMD fired a shot across NVIDIA’s bow. AMD released a new series of video cards aimed squarely at the midrange performance sector: the Radeon HD 4850 (~$200-$225) and Radeon HD 4870 (~$300-$325).

A quick overview of the standard specifications of both cards:

The big news here is that AMD’s midrange offerings are now positioned directly in line with NVIDIA’s midrange parts, and in many benchmarks, they surpass the performance of the competitor's parts at the same price point.

NVIDIA’s new cards on the market (GeForce GTX 260 and GeForce GTX 280) are positioned in the mid to high end range, and while the GeForce GTX 280 surpasses both new parts from AMD, it also has a price point of around $500. The GTX 260 competes directly with the Radeon HD 4870, yet it has a price point of around $400. Although the performance of the two cards is very close, there is almost a $100 difference in cost to the end user.

In the end, both companies have a very strong selection of products across all price points, and which type of card you choose could depend on any number of factors not mentioned here (i.e. power draw/efficiency, cooling, driver quality/features, etc.). One thing is certain: competition between these two gaming hardware giants is great for the consumer as you won’t have to frag your wallet to get a video card that will last you for several years. See you online!

No harming of USB Flash Drives occured during the making of this blog entry

Out of all the storage devices I have seen come and go in the past the USB Flash drive has to be my favorite. Don't get me wrong, I still love the look and feel of a 100MB Zip disk, and even get a kick out of burning a few CD's here and there (legally, of course), but my recent near miss experience involving a Kingston Traveler USB Flash Drive and a washer machine ultimately sealed its fate as the most convenient and waterproof form of file backup/transfer available.

Let's just say that I am a little absent-minded when it comes to removing articles from laundry bound clothing such as wallets, cell phones, pdas, and now USB drives. After a complete rinse cycle in an energy effecient front-loading washer and 50 minutes of permanent press in the dryer I was amazed when the USB Flash drive lit up after I put in my computer and no harm or data loss occured.

Granted, the purpose of these drives is not to withstand such harsh environments, but their usefulness, and now ruggedness, has certainly made a believer out of me. I'm not saying you should give up those 100MB Zip Drives, nor am I condoning the harming of USB Flash drives (they have feelings, too). At their affordable entry level prices, starting less than ten bucks, I'd simply recommend experimenting for yourself.
