The motherboard is a primary circuit board of a computer, functioning as a giant communication highway. It contains slots and ports for other components, such as video cards, sound cards, and peripheral ports. It manages the communication between all the components and the processor.
Types of Motherboards
Kinds of Motherboards include the following:
Advanced Technology (AT) motherboard
An AT motherboard uses an older format that requires cables to go through the back side of the computer case. It has connectors for the external ports. It requires a separate power supply, usually a transformer that provides 5- or 12-volt power to both the motherboard and the drivers.
Advanced Technology Extended (ATX) motherboard
An ATX motherboard has its ports hard-wired to the board, allowing the cables to be projected through the back of the computer case. Its power cable connectors are easy to use and it does not require a separate power supply. Most models support processors with the same pin patterns or electrical connections.
Choosing Motherboards (Buying tips)
PCI slots: Choose a motherboard that comes with several PCI slots that allow you to connect several expansion cards, such as sound cards and TV tuners.
Compatibility: Choose a motherboard with an interface compatible with your computer memory, hard disk, graphics card, and other internal components.
