A computer has different parts namely; CPU, motherboards, RAM, ROM, keyboard, Mouse, BIOS, etcetera.

The mainboard of a computer is it’s the brain and it’s the base of operation. The mainboard of a  desktop PC’s computer might be different from that of a laptop computer. They come in different shapes and sizes. The mainboard serves as the actual base for many of the other components inside your computer.

The Central Processing Unit (CPU) also known as the Microprocessor is the brain of the computer. The CPU is a circuit containing a large number of tiny transistors. The CPU performs all vital calculations necessary for the computer to work well. Another name for the CPU is the Decision Maker. And this is possible because the transistors in the CPU control are the data.  

Another extremely important component of a computer is its memory. The company memory is grouped into two which are;

Any data stored in the ROM of a computer can be read by it but it can not write new data to it. As for the RAM of a computer, it can not only store data but can also write data to that memory. Without its memory, every calculation of a computer would be pointless. This means that

Every process of a computer would have to start all over because there would be no way to save information from one moment to the next. And as you know that would be frustrating. 

Many desktop PCs have the space for extra RAM. All the user has to do is to open the computer and plug the RAM into the correct socket on the mainboard. Other computers don’t have a capacity for additional RAM because they are sealed systems and which makes it impossible to open and change them and make any changes, so you become stuck with whatever you’ve got. 

The basic input and output system [BIOS] of a system also called the chip works side by side with the CPU. The BIOS  is an explicit kind of ROM. It is the spine of the computer just as the CPU is the brain of the computer. Exchange of information between the software running of a computer and its hardware content is made possible with the aid of the BIOS.

The mainboard, CPU, ROM,  RAM, BIOS does the major work in the computer process. They are in charge of distributing resources to applications to enable them to run smoothly.

They also accept data from devices like Keyboard, mice, and other computers.

The graphics processing unit (GPU) is grounded under the “guts” of a computer because some have their Microprocessor (CPU). It takes so e of the load from the CPU by handling the processing power needed to form great graphic designs.

The GPU is divided into five parts.


Wi-Fi cards and modems,


graphics cards and sound,

Cooling system.

Every part of the computer is unique in its way.
