The more often you make changes to a file,repparttar 107773 more disorganizedrepparttar 107774 cluster becomes, andrepparttar 107775 disk becomes fragmented. This makesrepparttar 107776 magnetic head that reads and writes data to and fromrepparttar 107777 disk, works harder to retrieverepparttar 107778 entire file.

What's available?

The more you haverepparttar better it is. A lot of PCs still come with 128 MB RAM-we advise you to go for 256MB atrepparttar 107769 very least. If you're a gamer or into heavy graphics, you'll need more than 256 MB. Nowadays, DDR RAM is available for faster output. How much do you need?

Video RAM---What is it?

This is a card that carries outrepparttar 107770 processing for all that's related torepparttar 107771 display. You could have a fast processor, lots of ROM and hard disk that keeps pace with it all. But ifrepparttar 107772 display can't match all this-the speed at whichrepparttar 107773 things have got processed will take ages to show up on screen. The card has its RAM- called video RAM (VRAM).

What's available?

As we said earlier, some motherboards have this function inbuilt, but others need you to have a graphics card for this. You get a range of cards now.

How much do you need?

If you're into heavy gaming and graphics and CAD and 3D modeling, you need to have a card with at least 16 MB VRAM, 32MB if you can afford it. For other purpose, 16 MB VRAM is good enough.

All software comes on CDs. A lot of computers magazines that teach you how to use computers come with CDs. So a CD-ROM drive is a must. Now you haverepparttar 107774 option of going for CD-RW drives or even DVD drives. And some vendors haverepparttar 107775 check to see PCs without them.

Higher X ratings-such as 48X, 52X for a CD drive doesn't mean thatrepparttar 107776 drive will run at blazing speeds. In fact for routine things opening a CD tray, making a CD auto run-an 8X will do just fine. But if you were to rip songs from your audio CDs to convert them into MP3s you would need a faster drive.

A DVD drive is great if you are going to be watching a lot of movies on your PC- but make sure video card and sound card and speakers match up to it.

Go for a CD-RW drive if you are going to be burning a lot of CDs-keeping backups, making MP3 CDs, and so on.
