CPU (central processing unit) is the brain of the computer. Just as our brain controls all the different parts of the body and makes them work together, the CPU controls all other parts of the computer and makes them work together. All other parts of the computer are connected to CPU.

The Keyboard is made of several small buttons called 'keys'. Each key corresponds to a number or a letter or some special function. Just as you use a pencil to write on a paper, the computer needs a keyboard to tell it what to do. 


A mouse is a pointing device that controls the movement of a pointer on the screen. A mouse can have one to three buttons that can be clicked to perform actions on the computer. Clicking the mouse once is called a single click while clicking it twice in quick succession is called a double click. Depending on which side the clicked button of a mouse is, it may be called a right click or a left click. 


A monitor is like a television; it shows us what work the computer carries out. This has a power (on/off) switch. Turning the monitor off does not turn off the computer. There may also be other buttons to be used for adjusting the image. The glass surface of the monitor is called the screen, whereas the monitor is the entire box with the screen, case, stand and buttons.
