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.
