. The related term "jack plug" refers to a male connector, and is generally shortened to simply "plug".

Some connector styles may contain male (pin), female (socket) or both connection types. Therefore, the use of gender to describe a connector "jack" or "plug" may be misleading. A jack is better described as a receptacle that is designed to be mounted (fixed) on the surface of a bulkhead or enclosure.
