CPU socket

Socket 370 processor socket

The term CPU socket (or CPU slot) is widely used to describe the connector linking the motherboard to the CPU(s) in certain types of desktop and server computers, particularly those compatible with the Intel x86 architecture.

Most CPU sockets and processors in use today are built around the pin grid array (PGA) architecture, in which the pins on the underside of the processor are inserted into the socket, usually with (ZIF) to aid installation. In contrast to this, a couple current and upcoming sockets use a land grid array (LGA) in which the pins are on the socket side instead and come in contact with pads on the processor. Slot based processors are cartridge shaped and fix into a slot that looks similar to expansion slots.
