a floppy drive (often called drives “a” and “b” on a computer running dos or windows) can be connected to or installed in a personal computer (pc). it is the part of a computer that reads and writes the disk that can be removed. a disk, often called a "floppy disk", is used to store files and carry them from one computer to another by using the floppy drive. the floppy drive reads the disk (or diskette) and the user is then able to open and change the files saved on the disk.
