Connectors• A plug is a part with some type of projection that
goes into a port. • A port is a part that has some type of matching
hole or slot that accepts the plug. • You never put a port into a plug; it’s always the
other way around. • The term jack is used as an alternative to port, so
you may also put a plug into a jack. • The term connector describes either a port (jack)
or a plug.
