CPU Sockets
5 (100%)1 vote

The term CPU socket or CPU slot is widely used to describe the connector linking the motherboard to the CPU in certain types of desktop and server laptops, 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. To aid installation, zero insertion force sockets are usually used, allowing the processor to be inserted without any resistance, while gripping the pins firmly once the processor is in place to ensure a reliable contact.

An alternative to the PGA architecture is the land grid array (LGA) in which the pins reside on the socket rather than the CPU.

In contrast to CPU sockets, slot based processors and CPUs use a single- edged connection rather than a socket and slot into the motherboard.
