Question

why the name of directory in computer don't start with letters 'a' and 'b'? (like local disk C:)

Answer 1

Explanation:

On IBM compatible computers (PCs) running a Microsoft operating system, such as Windows or MS-DOS, the hard drive is the C: drive because it is the first available drive letter for harddrives. The computer assigns the A: and B: drives to floppy disks and sometimes other removable media, such as tape drives
