What is motherboard?

When you open your computer for the first time, you will soon get a 

flat board screwed on the inside part of the case. That is what we 

call computer motherboard - the most important of all other parts.

You see that every part in the case is connected to this board directly

or indirectly. As you observe thoroughly, you will soon realize that no 

part is left out without connecting to the board.

To define, computer motherboard is the main electronic circuitry of a computer. It holds all parts together. It is the chief of all parts, without it there is no called ‘computer’.

Often it is referred as “System Board”, “Main board”, “planer” 

Its function

The main function of a system board is providing a way so that all the parts work together. It allows various components of a computer to communicate each other. 

Types of computer motherboard

There are varieties of main board available on the market, which differ in size, layout and the type of components fit into (normally the process socket type). We may differentiate boards as standard and non-standard (not popular way). Standardized boards are interchangeable and easy for upgrading than non-standardized ones.

Generally, board types are determined by two major factors:

• Form factor
• Type of processor they designed for

Form factor refers the physical dimensions of a system board. Not all motherboards fit into the same case. Knowing your form factor will let you know what type of case you are to buy.

Some of the system board form factors include: -

-ATX (the most common board found in most systems)

-Micro ATX

-NLX

-WTX (found in workstations and expensive) 

-BTX
