Are you looking to learn more about Motherboard basics? You’ve come to the right place! In this updated guide, we’ll answer all of your questions including what exactly a motherboard is.

Plus, we’ll explore the differences between motherboards and PCBs. By the end of this post, you’ll be an expert on Motherboards! So let’s get started!

What is a motherboard and what does it do in a computer system?

A motherboard is a printed circuit board (PCB) that contains the circuitry necessary to connect and power all of the components of a computer.

It typically includes slots for mounting expansion cards, memory modules, and other devices. The term “motherboard” is used to refer to the primary PCB in a desktop computer, laptop, or server.

The motherboard is the heart of a computer system. It contains the central processing unit (CPU), Random Access Memory (RAM), storage devices, and input/output ports.

All of these components must be connected to the motherboard in order to function properly. In a desktop computer, the motherboard is typically mounted inside the computer case. In a laptop or server, the motherboard is often integrated into the device itself.

The different types of motherboards and their features:

There are different types of motherboards available in the market. Some of the popular ones include ATX, microATX, and mini-ITX. Each type has its own set of features and specifications.


The full form of ATX is Advanced Technology Extended. It is one of the most commonly used motherboard types. It supports a variety of hardware components and has ample space for expansion cards.


As the name suggests, microATX boards are smaller in size as compared to ATX boards. They are ideal for building compact PCs. These boards offer fewer expansion slots as compared to ATX boards but they are cheaper and easy to install.

Mini-ITX: Mini

ITX is the smallest form factor for motherboards. These boards are suitable for building small form factor PCs. They have limited expansion slots but they offer better energy efficiency and performance.

Features of a good motherboard:

There are certain features that make a motherboard ideal for use. Some of these features include:

  • Support for a variety of hardware components: A good motherboard should be able to support a wide range of hardware components such as processors, memory, graphics cards, etc.
  • Expandability: A good motherboard should offer ample space for expansion cards. This will allow you to add more features to your PC in the future.
  • Overclocking: A good motherboard should allow you to overclock your processor to get more performance out of it.
  • Energy efficiency: A good motherboard should be energy efficient to save on power consumption.
  • Reliability: A good motherboard should be durable and reliable.

How to install a motherboard in a computer system?

A motherboard is a Printed Circuit Board (PCB) that houses essential components of a computer system, providing connectivity between those components.

The motherboard is the main circuit board in a computer and it is also known as the mainboard, system board, or baseboard. It is the largest and most important circuit board in a computer. 

A typical desktop computer has its microprocessor, main memory, and other essential components connected to the motherboard.

A motherboard also typically has connections for secondary storage devices and peripheral devices. The term “motherboard” refers to the physical structure of the board, not its functionality or capabilities. 

The first thing you need to do when installing a motherboard into your computer case is to remove the old motherboard.

You will need to unscrew and remove all of the cables and devices that are attached to it. Once you have done this, you can then begin installing your new motherboard. 

To install the motherboard, you will first need to line up the holes on the board with the corresponding standoffs in the case. Once you have done this, you can then start screwing in the standoffs until they are tight. Be careful not to overtighten them, as this could damage the motherboard. 

After you have installed the standoffs, you can then begin attaching all of the cables and devices that were previously attached to the old motherboard.

Make sure that everything is plugged in correctly and securely before moving on to the next step. 

The final step in installing a motherboard is to install the CPU and heatsink. First, you will need to remove the protective cover from the socket on the motherboard. Then, you will need to line up the notches on the CPU with the ones on the socket and carefully insert them into place. 

Frequently Asked Questions

Is the motherboard a PCB?

Printed circuit boards, or PCBs, form the basis of motherboards, since they not only physically connect components to the board, but also supply the signal paths electrically tying them together as well as the ground and power layers that provide the current needed to run them.

What is the difference between motherboard and PCB?

Generally, the PCB consists of a fiberglass board and copper traces. The components are excluded from this definition. Motherboards serve as the central main component of a computer by combining PCBs with additional components. It is here that the CPU of a PC is located, along with other applications.

Who invented motherboard?

In 1981, IBM introduced its first personal computer (PC) with the world’s first motherboard.

How many types of motherboards are there?

A motherboard can be divided into three categories, based on its size: ATX, Micro-ATX, and Mini-ITX. The micro or mini boards can be used in smaller chassis, but there are fewer PCIe slots, RAM slots, and other connectors available.

Final Words

So, is motherboard a PCB? The answer to this question is not as straightforward as you might think. While the two terms are often used interchangeably, there are some key differences between motherboards and PCBs.

In general, motherboards tend to be larger than PCBs and they include more components. If you’re looking for a more specific answer, we recommend checking with the manufacturer of your motherboard or PC.
