DIN connector - technical definition

(Deutsches Institut fur Normung connector; German Standards Institute connector) A family of plugs and sockets used to connect mice and keyboards to the computer. DIN connectors are also widely used in the audio world.

Keyboards and Mice
The first two generations of PC keyboards (PC and AT keyboards) used a 5-pin DIN connector. The smaller 6-pin Mini-DIN connector replaced the 5-pin "AT" connector, and 6-pin to 5-pin adapters were commonly used to attach a new keyboard to an old PC. The 6-pin Mini-DIN also replaced the serial port for mice. See PC keyboards.
