Mother board and its Functions

Components of a Motherboard

Most commonly mother boards are of two types AT and ATX main board. At motherboards are now completely eradicated from the use. The ATX main board is 12 inches in width and almost 9 inches deep. ATX is relatively more reliable and it has 6 -pin connector. ATX mother board has many components attached to it which are important for its functioning. The key components of the logic board are either at connector side or embedded inside the board. The components present ate the connector side are mouse connector, keyboard connector, USB ports, serial ports, VGA ports, power supply plug and Parallel ports. The other components include CPU chip, RAM slots, PCI slot, ISA slot, AGP, CPU slot and floppy controller. The peripheral devices which are residing on the mother board are either directly fixed on it or are entrenched using sockets.

Some Main Functions of the Logic Board

BIOS or basic input output and Boot memory also resides on the motherboard. BIO is a kind of software which works when we turn on the computer. BIO is also called a lower level program because it is installed in the hardware. The job of the BIOS is to act as a communication channel between motherboard and softwares. Mother Board plays a vital role in running the operations and programs on your PC. It is this printed circuit which contains chips and many expansion cards to facilitate your working. It does not matter which ever component you attach to your motherboard, the basic functioning of that device is dependent upon on the main board. Mother board also contains a chip set. This chip set is really essential as it monitors the data flow in your personal computer. It guides the movement and flow of data through the buses. Motherboard chipset guides the data towards the correct paths and ultimately correct destinations. This chipset also scrutinizes the processors direct access to the main memory. Therefore it is mother board where you plug in your video cards, memory, cache and cards.

Other features and Functions of Main Board

Motherboards are not produced in only one shape and size. The shape and the size of the mother board is adjusted depending on the need of the manufacturers. The size of the previous motherboards like AT were really large however now the size of modern main boards are prone to many changes. The mother boards cannot be discarded form the electronic devices because of their size. Today they have been modified into smaller units in order to become parts of smaller digital devices like laptops. This makes laptop computers really difficult to repair and upgrade sometimes. Only the manufacturer can help repair it again. This is because the design of the miniature main board is really complex. The presence of micro dies on the motherboard also makes it an expensive embellishment. This is the reason why small digital appliances are costly. Mother boards cannot alone load the memory and run the system for this purpose they need non volatile memory. Mother boards use BIOS in order to boot.
