ZIF socket
Short for Zero Insertion Force socket, the ZIF socket was designed by Intel and includes a small lever to insert and remove the computer processor. Using the lever allows a user to add and remove a computer processor without any tools. All processor sockets from the Socket 2 and higher have been a ZIF socket design.
