A contraption that contains or encases the ink, an inkjet cartridge comes in different combinations. With the proliferation of models of inkjet printers from various manufacturers, inkjet cartridges also come as separate black and color cartridges, black and color ink in one cartridge, and ink tanks for every ink color. An ink tank of several inkjet printers houses the control circuitry, which decodes the information transmitted from the computer to the printer, and the print head, wherein the nozzles are located.

Only a handful of companies supply printers with a built-in print head. The print head of some inkjet printer models are already incorporated and fixed inside the printer itself. The good thing about this is that a user need not replace the print head every time the ink runs out. On the other hand, the entire printer should be replaced or repaired once the print head itself is damaged.

By and large, a print head is connected to detachable and replaceable ink tanks. Most models of up-to-date inkjet printers are designed with this kind of setting. Unlike in a printer with a fixed print head design—wherein the entire printer has to be replaced if broken—this inkjet technology is not as costly since a user can just purchase a new cartridge if the print head breaks down. However, when the inkjet cartridge frays or runs out of ink, the whole cartridge should be replaced. A brand-name inkjet cartridge costs more than a laser cartridge, which makes inkjet printers costly and difficult to maintain and operate. However, cost-conscious consumers today have opted for compatible standard inkjet cartridges or make use of refill kits. These cheaper alternative ink tanks and refill sets or remanufacturing services appeal to economical computer-users but not to selected printer makers.

Your monitor is the single most expensive component in your pc system. This means that a lot of money can be saved if you make the right decision and choose the right cheap computer monitor. There’s a lot more to computer monitors than just the size of the screen. Read on to find out what to look for when choosing cheap computer monitors.

The features of a computer monitor: A computer monitor is like a high quality TV set. The difference is that with a computer monitor you sit very close and try to make out fine details such as words.

This means that a computer monitor must have very fine definition and an image that is nice and stable on the screen so you do not get eye-strain. You will spend a great deal of time staring at a computer monitor so it is important that you get one that suits you perfectly.

When you are looking for cheap computer monitors you will be given different specifications. These numbers can be confusing so let us look at what the specifications mean when you are sitting in front of your monitor.

Resolution: This is the number of pixels on the screen. Say your screen is set to 1024 by 768 it means that there are 1024 along the top of the screen. This means that if you had a picture that was 1000 pixels wide you could see the whole picture without zooming out and losing details.

Monitors will be described as having a maximum resolution. This will be the highest setting possible. Usually the monitor will have an optimum setting slightly below this resolution.

High resolutions are great if you want to look at graphics because more of the picture will fit on the screen at once. However if you are looking at text a letter 5 pixels high will get smaller and smaller as the resolution increases. This means that if you are only going to surf the net and do email then you will be wasting money and straining your eyes with a high resolution monitor.

All new 15 inch monitors will do 1024 by 768. If you are looking for a cheap computer monitor then get one capable of this resolution.

If things are too small then you can always lower the resolution to 800 by 600. You may also be able to raise the resolution but doing this will lower the vertical refresh rate. Read on to find out why you must spend more to get a monitor to run high resolutions.

Vertical Refresh Rate: This is a very important specification. The speed that a monitor draws an entire screen, called the “vertical refresh rate” or “frequency,” is measured in hertz (Hz).

To prevent eye-strain you want your monitor to be running the current resolution at around 85Hz. This will make the image stable. At lower refresh rates the screen will flicker and you may not notice it at first but you will notice the splitting headache you get after about an hour of use at a low refresh rate.

The vertical refresh rate dcreases as the resolution increases. In the monitor manual look for the resolution that has 85 vHz next to it. This will be the optimum resolution for the monitor. Setting the monitor any higher will damage both your eyes and your monitor over time.

Monitor size: This is easy to understand. Bigger monitors make the picture bigger so that you can have higher resolutions without text getting too small. This makes less work for your eyes. Buy as big as you can afford. Currently 17 inch monitors are great value. If your interested in having a look at some great prices for computer monitors then click the ad on both the right and left sidebar to find out the monitors that match your need.

Dot Pitch: In trying to evaluate a monitor’s quality, most people will usually talk about dot pitch. In general, the lower the dot pitch (measured in millimeters), the better the monitor. The problem is that dot pitch can be measured in many different ways, and therefore doesn’t necessarily mean much.

A low dot pitch will make text crisp but as I said there is no standard measurement to compare. Usually spending more money will increase the monitor quality.

I found the best way to ensure that a monitor has a nice crisp image is to buy a good brand. I found an excellent deal on Viewsonic 17″ monitors. Viewsonic is a trustworthy brand.

Choosing cheap computer monitors should take time. There are some excellent bargains out there at the moment. Remember if you don’t have a huge demand for a high resolution monitor then get a 15 inch. It will still display sharp graphics at low resolutions and at these low resolutions things will be nice and big for your eyes.

Soon your computer doesn’t reboot properly, and you hear that ugly grinding sound that means all of your precious data has been wiped out. What did you to protect hard drive data? It’s too late to think about it after the fact.

Here are 5 ways to save and protect your hard drive and ensure it can keep working when you switch to a new drive.

1. Backup Your Data

You’ve heard it many times before – the best way to protect hard drive data is to backup your data. There are many ways to backup your data. Copying personal files to another disk is one method, but it’s time-consuming and manual. It’s better to use an automated backup solution that can perform backups at scheduled intervals.

One such product is bundled with Windows XP Home and Professional editions. The file is called ntbackup.exe. It’s automatically installed with Windows XP Pro. If you have Windows XP Home edition, you can locate the file in your Windows CD ROM in the valueaddmsftntbackup folder.

Then run ntbackup.msi to run the backup program. The backup program will backup your files to a backup file. Once you’ve made your backup, you need to know how to restore your files from your backup. You may need to reinstall Windows so keep your original installation discs handy.

If you want to avoid reinstalling Windows then consider making an image of your hard drive. Backup programs can make an image of your whole disk without the need to reinstall Windows.

2. Password Protection

Password protection and data encryption are one of the most basic ways that users can protect hard drive contents. To change your password in Windows just access your account from Control Panel -> User Accounts and then click change my password.

Now you want to encrypt your data, which will scramble it for everyone but you. Please note that encryption is available in Windows XP, but only for NTFS file systems. To encrypt a file or folder, right-click on it, go to Properties -> Advanced tab and check the box labeled Encrypt contents to secure.

No one else will be able to read this data but you. You can make encryption easier by creating a popup menu. Go into the Registry Editor and locate

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows CurrentVersionExplorerAdvanced.

Select Edit -> New -> DWORD Value and name it EncryptionContextMenu.

Double-click this and enter 1 for the value. From this point on, you will be able to right-click any file or folder to bring up a popup menu with the options Encrypt or Decrypt.

3. Unleash the Windows Recovery Console

Imagine having your hard drive crash and not being able to boot up. Are you out of out luck? Not at all! Bundled with Windows XP is a powerful tool called the Windows Recovery Console. It allows you to repair file systems or folders so you can protect hard drive contents. Unfortunately by default the WRC is on a “leash”-it operates in a restricted or crippled mode on your computer. .

Lift the restrictions by opening the Local Security Settings editor in Windows (click Start -> Run -> secpol.msc). Go to Security Settings -> Local Policies -> Security Options and double-click on Recovery Console: Allow floppy copy and access to all drives and all folders. Check Enabled and Ok. That will set up you for full access. Should Windows ever crash, start the WRC and type set AllowAllPaths=True.

Start the WRC by putting your Windows XP CD into your computer and pressing ‘R’ upon reboot. Type your Administrator password. The command interpreter will appear. You can then run whatever commands you need or type help for a list of commands.

4. Make Room for Defrag

One way to save hard drive contents is to fine tune your defrag program. With defrag there are two files that will never defrag: your Master File Table and your swap file.

As the table of contents for your hard drive your Master File Table expands as you add more files. To protect hard drive MFTs you must allocate more space to them. Go into your Registry and locate the key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFilesystem. Find the value NtfsMftZoneReservation and type 2, 3 or 4. These numbers indicate how much of the hard drive to allocate to the MFT: 25, 37.5 and 50 percent respectively.

To expand your swap file make sure you have 256MB of RAM and click on the System icon. Go to Advanced -> Performance Settings -> Advanced and click Change. Select the No Paging File in Virtual Memory box and click OK three times. Reboot and run disk defrag. Then go back to Virtual Memory box, select Custom and set the Initial Size and Maximum Size to the same value (2 to 4 times your RAM) and your swap file will not fragment.

5. Get Rid of Old Junk

The final way to save hard drive units is to get rid of that old junk in your computer. These are unused programs on your computer that tend to slow down your computer’s operations. Uninstall them by going to Control Panel -> Add or Remove Programs.

Also you should invest in a good anti-spyware program as well. Spyware ads are those annoying popups that try to direct you to a merchant’s site. These programs reside on your computer and consume precious resources-until you remove them with a spyware or adware busting program.

Another area on your computer that you should definitely check out is your Temp folder. This is the folder where Windows dumps files that it is only using on an interim basis. If these files are left over after they have been used they can slow your computer down as well. You’ll find the Temp folder in C:Documents and Settings under your username. You can sort the files by their modified dates to determine which files you think are way too old and are safe to delete.

Conclusion

Computers, like any other piece of hardware, require routine maintenance and fine tuning to keep them running in optimal condition.

One of the most important components in a computer is a hard drive. In this article we looked at 5 ways to save and protect your hard drive. Most of the solutions presented here are commonsense solutions that require no technical expertise.

We’ve also included a tweaks that require some experience with the Registry editor but are not hard to implement. Using all of the solutions here on a regular basis will ensure that your hard drive will not go out before its time.
