==Computer industry terminology==
A '''plug-compatible''' machine is one that has been designed to be [[backward compatible]] with a prior machine. In particular, a new [[computer system]] that is plug-compatible has not only the same connectors and protocol interfaces to peripherals, but also [[binary code compatibility]]—it runs the same software as the old system. A '''plug compatible manufacturer''' or '''PCM''' is a company that makes such products.
