Many other names are used for jack sockets like a plug, a female connector, receptacle, etc., depending upon the system and how it is used.
A distinguishing factor of a jack socket like a 4-pole 3.5mm jack is that these are fixed in a certain device, waiting for a movable connector to be received to complete the electrical connection. For example, on a laptop, you will find jack sockets on the side for microphones, headphones, etc., just like the sockets in walls are design to plug in various electrical equipment. These jack connectors are also designed to work with different types of movable connectors.
