IBM Disk BASIC was a version of the Microsoft BASIC programming language licensed by IBM for the IBM PC DOS. It was included in the original IBM PC DOS and required the original IBM PC BIOS to run. The name Disk BASIC came from its use of floppy disks rather than cassette tapes to store programs and data. GW BASIC is a standalone compatible successor of IBM Disk BASIC that doesn't require the original IBM PC BIOS to run. A later version IBM BASICA (short for "Advanced BASIC") added features to support graphics, sound (on the built-in speaker), and event handling for communications and joystick presses. Neither version of IBM BASIC would run on on non-IBM computers or later IBM models, since those lack the needed ROM BASIC; the equivalent to BASICA for non-IBM MS DOS compatible computers was GW-BASIC.
