Components of computer Motherboard and their Function Explained

A motherboard is the main printed circuit board (PCB) of most computers and other expandable systems. A motherboard is a computer’s primary printed circuit board (PCB). All components and external peripherals link to the motherboard, which serves as the computer’s fundamental communications backbone. There are a lot of components on a motherboard. You may buy these motherboard components from a variety of websites, as well as best AM4 motherboards from the same websites, including but not limited to final desktop. Some motherboard components are critical, while others are not. Nevertheless, here are some of the most common Components of computer Motherboard and their Functions are explained below.

Buses for Expansion are needed.

Peripheral Component Interface is the abbreviation for Peripheral Component Interface. The CPU and peripheral devices are connected through the interconnect and extension bus. Expansion cards, such as graphics cards, sound cards, LAN cards, and other computer components, are plugged into these slots. PCI is the most widely used extension bus in computers and other hardware platforms. Buses transport data, memory addresses, power, and control signals from one component to the next. Other bus types include ISA and EISA.

Computer processor chipsets

A chipset is a group of small circuits that manage data flow to and from a computer’s major components. Among the most crucial components are the CPU, main memory, secondary cache, and any devices on the buses. The microchip also controls data flow to and from hard drives and other devices connected to the IDE channels.


On older computer motherboards, IDE (Integrated Drive Electronics) sockets were present. The most frequent connectors between a motherboard and storage devices like hard drives. SATA technology, on the other hand, is used on the most recent motherboards. This technology is utilised as a computer bus interface that can link several types of storage devices, including hard drives.

Parallel port

A parallel port is a sort of interface that allows peripherals to be connected to computers. This sort of port gets its name from the way data is transmitted. In other words, these ports transmit data at the same time. To accomplish parallel data transfer, parallel port cables comprise several data lines. The length of a cable of parallel port is greater than that of a contemporary serial cable, that only contains data line.

Time Generator 

An electrical oscillator (circuit) that creates a clock signal to synchronise the functioning of a circuit is known as a clock generator. A metronome for action coordination is created when the clock signal oscillates between high and low frequencies.

The Cooling system

A heat sink is a passive heat exchanger that allows heat from motherboard components to be transferred to a liquid or air-filled medium. As the fluid medium flows away from the device, it will evaporate. As a consequence, the temperature of the gadget is kept within a safe range. On the motherboard, the heatsink is utilised to keep the CPU, GPU, chipsets, and RAM modules cool.
