What are the different parts of a Computer ?

What is Computer?

The computer is an electronic device where you can do many things among them you can store data, process data, and also retrieve data. You can send an email, type documents, you can connect to the world through the internet by computer.


Different Part Of Computer


When we give some task to the computer we write that with the help of keyboard or mouse that is known as input that task is processed in the CPU(central processing unit) and when processing is completed, we see that result in our computer screen, which is known as output. Sometimes we want a printout of our result at that time we use a printer.


So here we see monitor, keyboard, mouse, printer, CPU. But behind this other parts or components are present inside the CPU which helps in processing these are


  1. Motherboard
  2. Central processing unit
  3. Graphic processing unit/video card
  4. Random Access Memory(RAM)/volatile memory
  5. Storage i.e Solid State Drive(SSD) or Hard Disk Drive(HDDS). 


1. MotherBoard


The motherboard is the main circuit board or mainboard where all the electronic components are connected. The motherboard is the main printing circuit board (PCB) where all the electronic peripheral devices are connected like CPU, storage devices, video card, audio card, network card i.e used to connect the computer to a network, clock generator, expansion card, power connector, etc. Supporting Chipset is one of the important components which an interface between CPU and the various external devices.

2.Central processing Unit(CPU)


CPU is the brain of a computer. The other name of CPU is the central processor, main processor, or just processor. It is direct connected to the motherboard. CPU executes instructions that are specified in the program these are logic, arithmetic, controlling, I/O operations, etc. When we give any instruction in any programming language CPU converts this instruction into computer language(assembly language) and then executes it.

3.Graphic processing unit/Video card


Graphic Processing Unit (GPU) is also named as the video card, graphic card, display adapter. This GPU is used for high-end visuals. GPU design for parallel processing is used for graphic and video rendering and in a wide range of applications. Another popular use of GPU is for games, creative production, and artificial intelligence(AI). IT helps graphic designers to create more realistic visual effects and realistic scenes with many lighting and shadowing effects.


4.Random Access Memory(RAM)


Random Access Memory(RAM) is also known as volatile memory. RAM is used to store machine code and working data for frequent access and the process by program but when the computer restarts the data erased due to these properties it is named volatile memory.


Multiplexing and demultiplexing are two types of circuits are present in RAM to connect data lines to the addressed storage for reading or writing the entry. RAM semiconductor memory is two types one is Static Random Access Memory(SRAM) and another is Dynamic Random Access Memory(DRAM).




The computer uses a special component to store data. That component is known as Hard Disk Drive(HDD) or Solid State Drive to store data. Hard disk drive contains a spinning platter. The spinning platter is coated with a thin magnetic coating and ahead moves over the platter. It writes 0’s and 1’s in small areas of magnetic north or south on the platter. When data is read the head goes back platter again and notices the same spots are in North and South. A trillion 0/1 bits per platter can store in the hard disk drive.

A Solid-State Device is also a storage device like Hard Disk Drive where data store but here data retains in flash memory as opposed to a magnetic-based system. If we come to know what is flash memory, flash memory is an electronic non-volatile, solid-state storage medium in computer memory. It can be reprogrammed and also erased.


A solid-state drive is defined by its ability to store information using the reliable attributes of a durable cluster of semiconductors. Because solid-state drives do not depend on moving parts or spinning disks, data is saved to a cluster of memory banks or semiconductors.
