Definition: A motherboard is a physical arrangement in a system that contains basic components and circuits of computer. In a typical motherboard, the circuit is imprinted or affixed on the surface of a firm surface and usually it is manufactured in a single step.
Types of Mother Board: The types of system mother board shouldn’t be confused with Form factors. Fundamentally there are two types of motherboards first one is integrated motherboard and second one is the nonintegrated system board:
Integrated Motherboard: In this type of motherboard, it has most of its components that are soldered on the board. This type of motherboard has several advantages and also some drawbacks. More space is conserved in integrated mother board and some other advantages are that it is portable and cheaper in manufacture.
Non-integrated Motherboard: The non-integrated system mother board has several expansion slots with detachable components like video adapter, disk controllers etc. The major advantage of non-integrated type of System mother board is its flexibility w.r.t replacement of faulty components. When there is a fault in expansion cards then it can easily be replaced.
Different Parts of a Computer Motherboard
Memory and their Slots: The computer memory is one of the key parts of the system motherboard. The total number of memory chips on a motherboard actually depends on the type of computer and its capacity.
Expansion cards: Expansion card is a typical component of non-integrated system motherboard as indicated earlier.
CPU and slots: CPU and the sockets is one of important part of the computer. This device is located on the right of the motherboard.
BIOS Chip: Just like CPU, the BIOS chips occupy the top position in terms of importance on the system motherboard.
Power Supply and Connectors: It is the electrical supply unit of the system. This is the unit that provides power to the system for smooth running.
Mouse Connector: The mouse is also a very important input device of the computer. Its connecting port is located on the motherboard.
Floppy and Hard Disk Connectors: The Hard drive is the mass storage device of the computer system, same with the floppy disk.
