Colon

A symbol that looks like two periods above each other ( : ) that is found on the same key as the semicolon on standard United States keyboards. An example of where colons are used with computers is when specifying a drive letter in MS-DOS. For example, typing in "A:" at the MS-DOS prompt would switch to the A drive or floppy drive and allow you to read a floppy diskette.
