Understanding Motherboard

What is a motherboard? Chances are, if you are reading this page, you already own a computer; but that does not mean you know everything there is to know about it. A motherboard is the primary circuit board on a computer. It serves as the foundation and main component of any computer.

A motherboard is the principal circuit board on a computer. The functionality and quality of a motherboard directly affects the functionality and performance of your entire computer system.

Why Is A Motherboard Important? – Importance Of Motherboard

A motherboard is the most crucial part of any computer as it holds all the components that work together in order to provide the user with seamless and effective services.

It has a large surface area which connects or interlinks different components. It serves as a connecting center of the system where one can easily interchange electronic devices such as a video card or hard drive. It is much similar to the trunk of a tree through which one can see the branches, leaves, and fruits.

If a motherboard were to become defective, the computer would cease to work. hence, a mother board is an integral part of any computer system. The motherboard is located in the front next to the CPU and interconnects all components together.

The motherboard is responsible for connecting all other hardware devices to the CPU like audio capacitors, RAM, and PCI slots. Above all, motherboard gives out the power supply to these devices, produces and controls the voltage that is supplied to these devices.

Here is why a motherboard is important:

1. Contains BIOS Chip

The BIOS chip is a Read Only Memory (ROM) chip containing program code as well as the necessary settings for a system to boot up. BIOS is an acronym for Basic Input/Output System and this BIOS chip controls data flow from input peripherals like keyboard, hard disk drives mouse and output peripherals like printer or monitor.

2. Manages All Synchronizations

The motherboard is fitted with a quartz crystal. This tiny yet special part acts as the motherboard’s clock. It sends out a signal to let all the components know when to send and receive signals and when not to.

The motherboard will not send or receive any signal when the clock is high or low, ensuring that the many different components work in perfect harmony.

Synchronization is everything! Without the clock on your motherboard, the other components would not be able to communicate with each other.

3. Motherboard Connects All Other Components

The motherboard is the bridge that connects all of a computer system’s components to one another. It also provides capabilities, such as storage (through a controller or chips present on the motherboard), USB ports, additional networking capabilities and sound card capability.

All motherboards are made up of a motherboard chipset and various slots designed to allow the connecting of various devices, such as the display, mouse and keyboard inputs, sound cards, and network cards.

The chipset is responsible for managing the majority of communication between the different hardware components.

4. Handles Hardware Expansion

Building a PC without expansion capabilities is like building a house with no windows or doors. The PCIe (Peripheral Component Interconnect Express) interface is the foundation of the PC, because it allows you to add cards such as video and sound cards.

5. Contains The CMOS Battery And Chip

Your motherboard contains a small, but essential, battery known as the CMOS (Complementary Metal Oxide Semiconductor). This battery saves your system settings and keeps them in place even when you turn the computer off.

Your computer motherboard contains all sorts of important circuits that control its inner workings. Therefore, it makes sense that the motherboard contains a memory component to keep track of all the settings and parameters for these components in relation to each other.

The CMOS chip on your motherboard oversees storing the majority of these parameters that allow your computer to run successfully.

6. Controls Power Supply To Components

The motherboard, or the main circuit board of all computers, has some main job functions. One of these is to serve as a main contact point for all the components of a computer.

These components need to receive power from this board in order to function properly.However, there are also smaller, optional components that are connected to the Power Supply Unit (PSU).

Since it is the main common ground for all the hardware, it makes sense for the power supply rail for the motherboard and all its connected hardware to run directly in line with it on top of things.

Motherboard Components and System

With a motherboard, you will be able to power your CPU. The motherboard will let you use your RAM, display your video output on the monitor, and run other peripherals such as a hard drive.

Here are some of the components that motherboard features:

  • RAM slotfor memory installation
  • Motherboard chipset that relays information
  • CPU socket that allows for CPU installation
