A computer hard drive is the storage disk needed to enable data to be saved, be it software or folders. Everything that is built into your computer needs to save onto the hard drive so the processor can stream the data for usage.
A hard drives memory is measured in gigabytes. Most standard computers will offer a 40GB drive, though the more you pay the more gigabytes you will have to play, with some top end computers from good value providers such as Dell Australia feature up to 320GB of storage space. It is also possible to buy an external hard drive to save information on. - though don’t use this as your only source of saving like I did, and lose 7 years of work in one foul swoop!
Most laptop hard drives run at 3 different speeds - 4200rpm, 5400rpm and 7200rpm. RPM stands for Rotations Per Minute and the more rotations you have, the quicker you hard drive will locate the information you require and feed it to the processor.
Hard drives are generally easily replaceable (though slightly more difficult in notebooks / laptops), but the information stored on them is not. So please people, back up your back ups. No human being should ever have to feel the way I did when I realised my whole life had disappeared because of a faulty plug!
