Computer Hardware Terms, Glossary and Dictionary

IEEE-488, now 488.1, is a communication bus standard that allows up to 15 devices to share a single bus by daisy-chaining, with the slowest device participating in the control and data transfer handshakes to determine the speed of the transaction. The maximum data rate is about one megabyte per second. IEEE-488 is based on the Hewlett-Packard Instrument Bus (HP-IB).
