1. Monitor – This is the thing that can be seen on the go, it is also called display. Everything that works is displayed in it.


2. Mouse and Keyboard – These two input devices are the latter. Pointing is done with the mouse and typing is done with the keyboard. They are called input devices because they send instructions to the computer so that it can do the work it does.


3. Cabinet – It is a box that keeps all the different parts of the computer. It consists of motherboard, hard disk, CD drive, processor etc. which work together to form a computer.

What is inside the cabinet:


4. Motherboard – It is a circuit board. All the data of the computer starts accumulating inside it.


5. Processor or CPU – it is the head of the computer which is attached to the motherboard. It controls everything on the computer. It is called a computer driver.


6. Hard disk – all information is stored in it. When you save a document, when you save a file, everything gets saved in it. If it is destroyed for any reason, all your data will be permanently deleted.


7. CD drive – It is like a hard disk. You can save all the information in it separately. When you need a file. From it you can copy to harddisk.

8. SMPS – It supplies power to the machine. First, the electricity goes to it, then the motherboard and other things decide how much electricity will go to it and send it through it. Apart from these, there are other things like UPS which is equal to a battery and helps to run the computer if there is no electricity. After that, if the speaker is connected to the computer, the sound will be heard. Now what I have said is part of computer hardware, but only this will not start the computer. It will also require software. About the software can be said in another part.
