LGA stands for Land Grid Array and it is used in computer motherboards to serve as the physical interface for microprocessors. It is a type of packaging for integrated circuits in which the pins are placed on sockets, unlike other forms where the pins are connected directly to the ICs. Older forms like PGAs or pin grid arrays involve pins on the microprocessor chips.
The socket is the physical interface a processor connects to. In the case of an LGA socket it consists of a series of pins which correspond to flat connectors on the bottom of the processor. New processors usually require a different array of pins, which means a new socket is born.
