Some keyboards are programmable and uses the EEPROM or Electrically Erasable Programmable Memory, which holds data, acting like a very small hard drive.

Cables and Connections

Wired keyboards will have a cable that connects to the rear of the computer through a serial connector. There are two types of keyboard connectors. The large 5-DIN connector or Deutsche Industrie Norm was used on the first systems up to the mid 1990s.

The smaller 6-DIN was made by IBM for the PS/2 and later model computers. Each pin provides a special function to transfer data to the computer.
