If you have an older computer and a knew disk
They allowed us to put more storage on computer hard drive disks.
Computer hard disk drives may be made of a stack of one or more disks (made out of metal or ceramic) covered in a magnetic "paint". Each of these disks is called a "platter".
A machine that reads data from and writes data onto a disk. A disk drive rotates the disk very fast and has one or more heads that read and write data.There are different types of disk drives for different types of disks. For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks.Disk drives can be either internal (housed within the computer) or external(housed in a separate boxthat connects to the computer).

The data hard drive or just hard drive is where all your programs are stored when your computer is shut down. Every progam you see on your computer is stored on the hard drive. That's why the bigger the hard drive the more programs you can put on your computer.
Short answer: An external hard disk is a removable hard disk. Longer answer: A removable hard disk is any hard disk which is designed to be easily removed from the computer. This includes, but is not limited to, external hard disks. There are also internal hard disks which are removable via a special slot in the front of the machine. Flash-based usb thumb drives are also frequently referred to as "removable hard disks." Even though they are not hard disks at all the OS treats them as such, and so for all practical purposes they can be considered removable hard disks.
hard disks are generally contains within the computer and contain FAR more memory than a floppy disk does. floppy disks generally contain 1.44 mb where as hard drives are constantly developing and are currently about 1TB MAX. floppy disks are external in the same way as CD's
Usually one in a typical home PC. Power users may have more. Servers can have arrays of hundreds of disks
no
yes,Because the hard drive is for store files and folder and ram make computer run faster and more ram more faster.
No the more sorter computer you have the more G.B. you have
A hard drive contain one or more hard (rigid) magnetized disk on witch data are recorded. Its named so to differentiate from flexible magnetized disks used in obsolete now floppy-drives.
