Components of a motherboard Chipsets The chipset of a motherboard refers to the collection of semiconductor chips that provide interfaces for expansion cards, memory, peripherals, and interfaces. The make and model of a chipset depends on a particular Original Equipment Manufacturer (OEM). Each chipset is designed to offer certain features such as onboard audio and video functionality. Chipsets are divided into two main categories—Northbridge and Southbridge: NorthbridgeThe Northbridge is a chipset that does not refer to any brand name but is the technique used to allow communication among high-speed peripherals such as memory, the Peripheral Component Interconnect (PCI) bus, the Accelerated Graphics Port (AGP) bus and the Level 2 processor cache (L2 Cache).

Processor sockets are normally flat in shape and have several rows and columns of pins. It is not difficult to identify a processor socket on the motherboard. Most Pentium class processors are installed along with a heat sink and a cooling fan because they generate a lot of heat during normal operation. A processor slot is another way to connect a processor to the motherboard. Slots were used on earlier Pentium II and Pentium III processors. The processor is mounted on a special expansion card and is inserted vertically in the slot.
