What is a computer cabinet?

Computer Cabinet :-

It is in the shape of a box, it contains some delicate and important parts of the computer which remain locked inside it. This box is made of materials like iron, plastic and fiber and this box is called Computer Case or Computer Cabinet. Due to incomplete knowledge of Computer Cabinet, many people also call Computer Cabinet as CPU, but this is not correct. CPU is a central processing unit which is installed on the motherboard, which we also call processor.
