Except monitor, keyboard and mouse, all of the hardware components are located in one place named computer case. And among all of those components, motherboard becomes the most important part inside computer system. Without this component, your computer will not able to operate because motherboard is the place where CPU, RAM and the other peripherals get connected. Motherboard or also known as mainboard is a large rectangular printed circuit board. It is a place where you can find most crucial electronic components which support the computer system, such as memory, CPU and integrated peripherals. Integrated peripherals which can be integrated on the mainboard are disk controllers, integrated sound card, integrated graphics controller, IrDA controller, USB 2.0 controller and fast Ethernet network controller.
