IEEE-488 is a short-range digital communications bus specification. It was created for use with automated test equipment in the late 1960s, and is still in use for that purpose. IEEE-488 was created as HP-IB (Hewlett-Packard Interface Bus), and is commonly called GPIB (General Purpose Interface Bus). It has been the subject of several standards.

General Purpose Interface [ˈdʒenərəl ˈpɜːpəs ˌɪntəˈfeɪs] (kurz GPI) bezeichnet eine plattformübergreifende Schaltverbindung zwischen Geräten verschiedenster Hersteller meist fernsehtechnischer Geräte.
