Why is Hard Drive important in Computer/CPU ?

Answer 1

Hard Drive is not a must for CPU. if only booting ur PC is ur goal then Make a DOS bootable floppy. insert it into floopy drive, boot from the floppy and enjooooooooy black and white.

Answer 2

The hard drive IS the CPU. CPU just means Central Processing Unit, which is the hard drive. It stores the operating system which runs the computer. No hard drive - no computer.

Answer 3

The hard drive is a device that contains all the information, all of your 'files' that make your computer know how to do what it does. Without it there is no way to save any file on your computer, install any program, and there would be a limit to how much information you could have it think about at once. It uses the hard drive as spare memory space when it needs it.

Answer 4

Nearly every desktop computer and server in use today contains one or more hard-disk drives. Every mainframe and supercomputer is normally connected to hundreds of them. You can even find VCR-type devices and camcorders that use hard disks instead of tape. These billions of hard disks do one thing well -- they store changing digital information in a relatively permanent form. They give computers the ability to remember things when the power goes out.

Hard disks were invented in the 1950s. They started as large disks up to 20 inches in diameter holding just a few megabytes. They were originally called "fixed disks" or "Winchesters" (a code name used for a popular IBM product). They later became known as "hard disks" to distinguish them from "floppy disks." Hard disks have a hard platter that holds the magnetic medium, as opposed to the flexible plastic film found in tapes and floppies.
At the simplest level, a hard disk is not that different from a cassette tape. Both hard disks and cassette tapes use the same magnetic recording techniques described in How Tape Recorders Work. Hard disks and cassette tapes also share the major benefits of magnetic storage -- the magnetic medium can be easily erased and rewritten, and it will "remember" the magnetic flux patterns stored onto the medium for many years.

In the next section, we'll talk about the main differences between casette tapes and hard disks.

Answer 5

the hard drive contains your operating system,the cpu contains the brains to run the os.

Answer 6

It is where the OS resides. It is where programs are and where files are stored. Without a HDD you would get nothing.

Answer 7

it is brain of the computer

Answer 8

it stores ALMOST all of your memory.. its the brain of the system
