What is difference between floppy disk and hard disk?
A floppy disk is a magnetic storage media. The floppy disk is a plastic disk
coated on both sides with magnetic recording material (ferrous oxide). It is
also called simply a diskette. IBM invented the floppy disk in 1972. The storage
capacity of floppy disk is very low (i.e. maximum storage capacity is 1.44 MB
for 3,5 inch floppy disk).
hard disk is most commonly used storage device in personal computers and
laptop computers. Most application programs and operating systems require hard disk for installation and operation. A hard disk is also called a hard disk
drive. It contains one or more metal platters. Each platter is coated on both
sides with magnetic material.
