Know the functions of the computer motherboard

Motherboard is the central component of the controller that regulates the work of all the components mounted on it. Regulate the provision of electrical power to each component. Data traffic are all regulated by the motherboard, starting from the storage device (hard drive, CD-ROM), a data input device (keyboard, mouse, scanner), or a printer to print.

Definition of Motherboard

Mother Board is a board or mother board or main board where all the devices are installed starting from the processor, memory, expansion slots, etc.. Mainboard is not as important as the processor. If the human body, the mainboard is a series of blood vessels and nerves. poor performance of a motherboard, will affect the performance of other peripherals. Therefore, choosing the right motherboard will greatly affect the performance of a computer.

how does a Motherboard work?

In computer systems, peripherals peripherals will be connected to each other-in the mainboard and can continue instruction through channels on board. The entire peripherals that are connected will be a complete computer system. A common function of a motherboard is forwarding the input data required in the course of processes in the computer.

Northbridge dan Southbridge 

The main chipset on the mainboard there are two Northbridge and Southbridge. Northbridge function is to bridge the flow of data around main memory and the processor and set the power management work. While the work function of Southbridge is set peripherals such as IDE Controller, PCI bus, AGP, and I / O functions other.

BIOS

In a motherboard, there is also an EPROM chip that contains the basic operating system that BIOS (Basic Input / Output System). The function of the BIOS is doing Bootstrap and Initialization hardware at boot time 

I/O Ports

I / O (Input / Output) ports are part of the mainboard to interact with the user through the medium of peripherals I / O such as keyboard, mouse, printer, and so forth. Most motherboards today have always had an interface PS / 2, USB, LPT, PCI, and Serial. All of these ports has its own characteristics and functions. The point is to allow a user to interact with the computer in performing his works.

Which should be considered in selecting or assembling a motherboard is that each Motherboard has different specifications for each brand or type. such is as below

1. Each Motherboard has a pair with a particular processor, where each motherboard has a socket type that is different for each type of processor.
2. Motherboard ability to be on the up-grade to a more processor speed. Motherboard are generally able to up-grade by replacing the processor. Information about this is very important to purchase a motherboard with consideration to be on the up-grade.
3. The capacity of RAM that can be installed on the motherboard. the larger the memory capacity provided more favorable
4. Slots are available for every type of RAM, for example, how many slots are provided for EDO RAM, SDRAM, etc..  
5. Setting motherboard BIOS (software) or jumper settings.
6. The number of slots for PCI and ISA. The slots are very useful for the addition of peripherals such as audio cards.  
7. Is support for AGP and VGA card, AGP support will be more profitable to stock if you want to improve the graphics capabilities of your computer by installing AGP card. 
8. Memory bus speeds up to how much speed (66, 100, 133, 200, 400 Mhz) 
9. Is the VGA card and the audio card has been already on board
