When we talk about computer board, I believe that the the most computer users used to heard main board or motherboard but rarely to hear system board. but these three words in computer hardware are the same. System Board controls communications for the entire computer system. Every component within the system unit connects to the system board. All external devices including the keyboard, mouse, and monitor connect to the system board. It acts as a data path and traffic monitor, allowing the various components to communicate efficiently with one another. The most desktop computer, the system board is typically located at the bottom of the system unit or along one side. It is a large flat circuit board covered with a variety of different electronic components including sockets, slots, and bus lines.
- Sockets provide a connection point for small specialized electronic parts called chips. Chips consist of tiny circuit boards etched onto squares of sandlike material called silicon.These circuit boards can be smaller than the tip of your finger.A chip is also called a silicon chip,
semiconductor, or integrated circuit. Chips are mounted on carrier packages.These packages either plug directly into sockets on the system board or onto cards that are then plugged into slots on the system board. Sockets are used to connect the system board to a variety of different types of chips, including microprocessor and memory chips.
- Slots provide a connection point for specialized cards or circuit boards. These cards provide expansion capability for a computer system. For example, a wireless networking card plugs into a slot on the system board to provide a connection to a local area network.
- Bus Lines provide pathways that support communication among the various electronic components that are either located on the system board or attached to the system board.
