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.
In home computers, game consoles and arcade-game hardware of the 1980s and 1990s, the term chipset was used for the custom audio and graphics chips. Examples include the Commodore Amiga's Original Chip Set or SEGA's System 16 chipset. The term chipset often refers to a specific pair of chips on the motherboard: the northbridge and the southbridge. The northbridge links the CPU to very high-speed devices, especially RAM and graphics controllers, and the southbridge connects to lower-speed peripheral buses (such as PCI or ISA).
