Mother Board

The motherboard is the main circuit board inside the PC which holds the processor, memory and expansion slots and connects directly or indirectly to every part of the PC. It's made up of a chipset (known as the "glue logic"), some code in ROM and the various interconnections or buses. PC designs today use many different buses to link their various components.

Wide, high-speed buses are difficult and expensive to produce: the signals travel at such a rate that even distances of just a few centimetres cause timing problems, while the metal tracks on the circuit board act as miniature radio antennae, transmitting electromagnetic noise that introduces interference with signals elsewhere in the system. For these reasons, PC design engineers try to keep the fastest buses confined to the smallest area of the motherboard and use slower, more robust buses, for other parts.Mmost modern motherboards come with the following features:

These are just some of the features that a motherboard may have as standard, some motherboards come with integrated components such as a sound card, graphics card, modem, NIC (Network Interface Card) and more.

All the components inside your PC connect to the motherboard in one way or another, a few examples: Memory banks are used for RAM modules.PCI slots are used to provide connectivity for PCI cards such as modems and sound cards. AGP slots are used for graphics accelerators. IDE interfaces are used to connect and control IDE devices such as hard drives and CD-ROM drives. Your choice of motherboard will depend on what processor you intend to use in your PC.
