CPU socket

Motherboards are subcategorized by the type of processor socket they have. The processor socket (also called a CPU socket) is the connector on the motherboard that houses a CPU and forms the electrical interface and contact with the CPU. Processor sockets use a pin grid array (PGA) where pins on the underside of the processor connect to holes in the processor socket. Computers based on the Intel x86 architecture include socket processors.
