Description:

As the primary communication device to the rest of the computer, the hard drive is very important. The hard drive stores most of a computer's information including the operating system and all of your programs. Having a fast CPU is not of much use if you have a slow hard drive. The reason for this is because the CPU will just spend time waiting for information from the hard drive. During this time, the CPU is just twiddling it's thumbs...
The hard drive stores all the data on your computer - your text documents, pictures, programs, etc. If something goes wrong with your hard drive, it is possible that all your data could be lost forever. Today's hard drives have become much more reliable, but hard drives are still one of the components most likely to fail because they are one of the few components with moving parts. The hard drive has round discs that store information as 1s and 0s very densely packed around the disc.
