A telephone jack (or phonejack) is a jack located on a wall that is used to connect a telephone or computer to the telephone line.
Before phonejacks were invented, the cord from the telephone actually went into the wall and the telephone was not movable unless you had a telephone worker come move the telephone to another location.
The tools and equipment used to install telephone jacks are a pair of needle nose pliers, a wire stripper, a screwdriver (phillips and flat) a small saw or sharp utility knife, telephone wire, electrical tape, a coat hanger that has been straightened out, and a wall plate.
Phone plugs were originally used in telephone switchboards and should not be confused with the registered jack-series plugs used to connect telephones to wall outlets.
The majority of professional audio equipment uses mono jacks as the standard unbalanced input or output connector, often providing a 6.3 mm unbalanced line connector alongside (or in a few cases in the middle of!) and as an alternative to an XLR balanced line connector.
Some designs of jack also have such a connection on the sleeve, as this contact is usually ground it is not much use for signal switching but could be used to indicate to electronic circuitry that the socket was in use.
