What is Motherboard? And How does it Works?

After all, what is a motherboard? MotherBoard is the main printed circuit board (PCB) of a computer. Having said this, you can also call the motherboard the central communications backbone connectivity point of the computer, through which all the components and external peripherals are connected.

You must have seen that a device to which all the equipment is connected, which keeps all the components connected together, is called a motherboard. The motherboard allows all the parts of a computer to receive power and communicate with each other.

What is Motherboard?

The motherboard is the backbone of any computer; it is a link through which all the components are connected to each other as if it is working as a hub through which other devices of the computer are connected.

These come in different formations according to the needs of a user so that they can fit his needs, budget and speeds.

Mainly, it is a PCB (Printed Circuit Board) that holds 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.

Everything is first connected to the motherboard. The motherboard itself enables this function to supply proper power to everyone so that they can do their work properly.

Definition of motherboard

The motherboard is a plastic sheet in which various ports are made to connect devices. The connection of each port is soldered to the motherboard, which we can see with our eyes also.

The motherboard is a very important device of the computer through which all the components of the computer are connected to the computer and can communicate with each other.

This is a circuit board that connects all your hardware to your processor. According to one approach, the motherboard is the basis 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

The motherboard also works like a platform, which makes many expansion slots available through which 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 Flow

Motherboard works like a communication hub through which all the peripherals are connected. Here the motherboard controls that all the peripherals can communicate properly among themselves. And motherboard manages data traffic.


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

How to Choose a Good Motherboard?

The motherboard alone is useless, but it is very important to operate the computer. Its main function is to hold the microchip of the computer and connect all the other components together.

All those things that help the computer to run or increase its performance are either a part of the motherboard or are attached to it through some slot or port.

The shape and layout of the motherboard is called Form Factor. It is with the help of this Form Factor that the motherboard design is decided. Actually, many specific Form Factors are used in which different types of standard motherboards are made.

If seen, there are many types of motherboards; such variation is because its design, cases, power supply and size are made as per the requirement.

A motherboard made by a specific manufacturer may support various CPUs and some memory. For this reason, motherboards should be selected only after careful consideration, not all motherboards support all types of components.

For this reason, choosing the right motherboard is very important. That is why I have mentioned some important things below so that you can get some idea for the right choice.

1. Processors

A very important feature of the motherboard is the socket that holds the CPU. Different boards require different socket connections, and not all have the same processor pins. Only from this socket will we know which model processor will fit in this motherboard.

2. Memory

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

3. Form Factor

The layout of any motherboard is called Form Factor. This Form Factor shows where various components should be placed and this reveals the design of that computer. Although there are many standards of Form Factor but it is used as per the requirement of the user.

4. Chipset

A Chipset is the middleman 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 has two parts: one is Northbridge and the other is Southbridge. All the parts of the computer communicate with the CPU with the help of this Chipset.

5. BUS

A bus in a computer means a path through which one component in any circuit connects to another. The speed of any bus is measured in MegaHertz (MHz). Speed only determines how much data can pass through that bus. The better the bus, the faster and more data can be transferred, hence better calculations.

5. Expansion Slots and Connectors

Expansion slots are those hardwired options through which we can add additional components to the motherboard. If you have to upgrade your system in the future, then you should definitely think about it. The more extra slots you have, the more components you can attach.

You can select a motherboard only by keeping all these things in mind. That is why I request you that before buying any motherboard, you should know well what your requirement is. You should buy anything as per your requirements.

Gradually, motherboards are becoming better and faster, and along with this, their cost is also decreasing. As the world is changing, the needs of people are also changing, which is why the shape, size and speed of motherboards are all changing. The day is not far when we can make the motherboard as we wish.
