Components of
computer motherboard

Familiarize yourself with the major components of computer motherboard, which is the most important part of a computer system.

It holds the following elements

CPU socket

Processor is a part that controls the activities of a computer. It is fitted on the main board and can be detached easily from the board. This behavior makes it upgradable and helps to identify the right processor type for your computer board.

The processor socket has its own specifications from which you should pick the right processor that matches with your board.

Memory sockets

Memory provides the working area for the CPU. Physically, the memory sockets are located very close to the processor. These sockets are for the RAM (Random Access Memory) memory chips. Depending on main board specs, it may have two or four sockets.

Chipsets

The computer motherboard contains individual components. These elements build upon the chipset, home of several controller of the parts on the main board. The chipset determines the type of components fitted on the board.

Chipset incorporates two sections – the North bridge and South bridge. The North bridge facilitates the communication between CPU, main memory and graphics card. It works at high speed since the CPU requires fast bus speed to process a large amount of data every second.

This processor also connects the South bridge with CPU.

The South bridge facilitates the communication between the various components such as storage devices, USB ports, expansion slots, CMOS RAM and clock.

Expansion slots

These slots are there to hook up additional peripherals, such as Sound Cards, Graphics Cards, Network Cards, Modems, TV cards … so on. On the modern computer, most of these cards fitted on the main board – means they are on board. No need to buy additional cards unless for better performance.

ROM /BIOS

BIOS – Basic Input/output system is responsible for providing startup instruction and configurations to a computer. Usually, the manufacturer writes on the ROM (Read Only Memory), it holds permanent instructions which tells how the computer starts and goes through a series of self-tests (POST – Power On Self-Test) before it is ready for a user.

System configurations of the BIOS are stored in CMOS (complementary metal-oxide semi conductor) which is powered by battery.

CMOS Battery

It is a lithium battery on the computer motherboard responsible for powering the CMOS.

Ports

Ports enable external devices to connect with the system board. Parallel, Series, USB, ports are among these groups. Presently, most devices come with USB connection.

Storage devices connectors

These are connectors fitted on system board used to connect with hard drive, CD/DVD drive and floppy drive.

Power connector

The power unit the components of connects through this connector.

These are the most common components of computer motherboard you should remember when you maintain or upgrade your pc.
