Motherboard:
The motherboard is, without a doubt, the primary component of the entire system. Without the support circuitry and functions this device provides, even the CPU is unable to work. A motherboard also known as main board, logic board, or system board. Typically the motherboard contains slots, and all the controllers required to control standard peripheral devices, such a display screen, keyboard and disk drive etc.
In addition to the hardware, the motherboard also contains some software. The system ROM actually contains three small, but very critical programs. These are the POST, theBIOS and the setup program. Power on Self Test (POST) is the program that initializes and tests each components of the motherboard every time it starts up to make sure everything is ready to run. The Basic I/O Service (BIOS) is a collection of very small programs that enable the system to communicate with hardware devices during the boot process. Finally the setup program is used to configure the features found on the motherboard.
Important component of the motherboard:
1. Chipsets:
Chipset is made up of one or more electronic components that connects the motherboard components such as, the processor, expansionand internal memory. Basically the work of the chipset is to control the system and its capabilities. Chipset determines the speed of themotherboard. It is also responsible for increasing the speed of the communication between processor and the peripheral devices. Mostly used chipset in the computer motherboard is Northbridge chip and Southbridge chip. Northbridge chip is the name given to the system controller chip. This is the chip that directly connects the CPU’s front side bus (FSB) to the high speed components of the system, which would include RAM, the AGP port and all other high speed peripherals. The FSB (also known as the external data bus) of the CPU must be able to synchronize with all the other devices. Where as the Southbridge chip is slower than the
