What is a Hard Drive?


A hard drive is nothing more than a magnetised storage area. Your Operating System is stored on your hard drive, as well as all your software programmes, like Microsoft Word. The hard drive is actually a few circular disks stacked one on top of the other. A little arm moves over the disks and writes things to these circular platters, and reads them. When you save a file or create a new folder, think of these circular platters being written to and you'll have a basic idea of just what your hard drive is.

A hard drive is given a letter of the alphabet for convenience sake, and in most computers this will be the letter C. That's why the hard drive is popularly know as the C Drive. There are other drives on your computer. These are the usual drives on modern Personal Computers:
