Do you know What is Motherboard? Motherboard is a main printed circuit board (PCB) of a computer. You can also call the motherboard as the computer’s central communications backbone connectivity point, through which all the components and external peripherals are connected. You must have seen that such an equipment to which all the equipment is connected, with keeps all the components connected together is called motherboard. The motherboard allows all parts of a computer to receive power and communicate with each other.

But nowadays there have been many changes in the motherboard, in which many features have been added. The capabilities and upgradeability of the computer have increased to a great extent. Today we will learn about this topic what is motherboard and how it works?


What is Motherboard?

It is the backbone of any computer. This is such a link that all the components are connected to each other as if it is working as a hub through which are the devices of the computer are connected. They come in different information according to the needs of a user so that they can fit and their needs, budget and speeds. Mainly, it is PCB (printed circuit board) which holds the various components of the computer so that the computer can be functional. Components like CPU, RAM, Hard Disk as well as TV Card, Graphics etc. All are first connected with motherboard. It only enables this function that everyone gets proper power supply so that it can do its work properly.

Definition of Motherboard

It is a very important device of the computer, through which all the devices of the computer are connected to the computer and can communicate with each other. This is the circuit board that connects all your hardware to your processor. In one sense, you can say that the motherboard is the base of the computer.

Functions of Motherboard

1. Component’s Hub

Motherboard works like a backbone of any computer in which other parts of the computer like CPU, RAM and Hard Disk are installed.

2. Slots for External Peripherals

It also acts as a platform, which makes available many Expansion Slots, so that we can install new devices or interfaces here.

3. Power Distribution

With the help of motherboard, power is supplied to other components of the computer.

4. Data Stream

It acts like a communication hub through which all peripherals are connected. Here the motherboard controls that all the peripherals can communicate properly among themselves and manages motherboard traffic.


The motherboard holds the Read Only Memory, the BIOS which is needed to boot up the computer. So it shows that computer starts with the help of motherboard.

How to choose Motherboard?

Motherboard alone is of no use, but it is of great importance to operate the computer. Its main job is to hold the Mirco Chip of the computer as well as connect all the other components together. All those things that help the computer to run or increase its performance or either a part of the motherboard itself or are connected to it through a slot or port. The shape and lay out of the motherboard itself is called Form Factor. With the help of this Form Factor, it is decided that how should be the design of the motherboard. By the way there are many specific form factors using which standard motherboards of different types are made.

If seen, there are many types of motherboard, such variation is because its design, cases, power supply and size are made according to the requirement. A motherboard made by a specific manufacturer may support a single variety of CPU and some memory. For this reason, the selection of the motherboard should be done after a lot of thought, not all motherboards support all types of components. For this reason, choosing the right motherboard is very important. That’s why I have mention some important things below so that you can get some idea for its right choice.

1. Processor

A very important feature of the motherboard is the socket that holds the CPU. Different boards require different circuit connects and the processor pins of or are not the same. From this socket only it will be known that which model processor will fit in this motherboard.

2. Memory

What kind of motherboard you are using, it is known that how much amount and which format of RAM you can use. Normally the memory of boards is somewhat limited as to how much amount of RAM it can support. But it would be best if you take a board that supports more RAM than you need so that you can upgrade it later.

3. Form Factor

The lay out of any motherboard is called Form Factor. It is from this Form Factor that it is known where to place various components and from this the design of that computer is known. Although there are many standards of Form Factor, but it is used only according to the requirement of the users.

4. Chipset

A chipset is the middle man of any computer, with the help of which data is transferred from one part to another inside the computer. It is like a spine that connects the microprocessor to other parts of the computer. In a computer, it has two parts, one is north bridge and the other is south bridge. All parts of the computer communicate with the CPU with the help of the chipset.

5. Bus

A bus means a path in a computer that connects one component with another in any circuit. The speed of any bus is measured in MegaHertz (MHZ). It is known from the speed itself that how much data can pass through that bus. The better the bus, the first and more data can be transferred hence the better calculation.

6. Expansions Slots and Connectors

Expansion slots are those hardwired option so that we can add additional components to the motherboard. If you have to upgrade your system in future than you much think about it. The more extra slots you have, the more components you can attach. Keeping all these things in mind, you can choose a motherboard. That’s why I request you that before buying any motherboard you should know very well what is your requirements.

Motherboard Manufacture Company

There are many popular companies in the market that manufacture motherboards such as:-



1. Who is the father of motherboard?
Ans. IBM engineer Patty McHugh is said to be the father of the motherboard.

2. What is the functions of Motherboard?
Ans. Component’s Hub, Slots for External Peripherals, Power Distribution, Data Flow, BIOS.
