COMPONTNT OF MOTHERBOARD Motherboard- The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interface, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disc drive. Collectively, all these chips that reside on the motherboard are known as the motherboard’s chipset. The parts of Motherboard are- 1. Processor 2. Northbridge and Southbridge 3. Expansion slot 4. Parallel port 5. Keyboard/mouse connector 6. Power connector 7. BIOS chip 8. Heat Sink. 1. Processor One of the easiest items to recognize on the motherboard is the processor. The processor is usually the largest chip on the system board and can be identified generally because it often has a heat sink or fan located on top of it. Classic Pentium motherboards typically have a socket 7 slot that the processor is inserted into. This socket is implemented as a ZIF (zero insertion force) socket, which means that the processor chip can be removed or added to the socket with very little effort. ZIF sockets typically have a lever that you pull to pop the processor out of the socket. Pentium II system boards had to implement a different socket for the Pentium II chip because the Pentium II chip was designed with a single edge connector and was inserted into the board standing up. The processor socket for Pentium II chips is called slot 1. 2. Northbridge and Southbridge The actual function of a chipset is to communicate between all components of the modern PC, or, to put it in other words, the chipset is the infrastructure. The chipset contains numerous components, and moreover, it makes various interfaces available for connecting additional components (PCI, USB, AGP, IDE, etc). As a rule, the chipset
