Computer Motherboards

A motherboard is the central or primary circuit board of a modern computer. It is also known as a system board or logic board.  Most motherboards produced today are designed for PC-compatible computers.  The basic purpose of the motherboard is to provide the electrical and logical connections for the other components of the system to communicate.  A desktop computer is built with a CPU, graphics video card, sound card, hard disk controller, memory (RAM), and other essential components on the motherboard. Other components such as external storage, controllers for video display and sound, and peripheral devices are connected to the motherboard via edge connectors and cables, although in it is increasingly common to integrate these "peripherals" into the motherboard.

Choosing a motherboard can be an overwhelming task. The industry boasts an incredible variety of motherboard manufacturers and models, and each motherboard is compatible with either a specific Intel or AMD processor. Since the motherboard is the heart of your PC, it is important to do your homework by reading motherboard reviews.
