My dear Rifat,

Your sweet note has just anchored my heart. Going through the letter I came to know that your school is going to start computer classes very soon. As you are very interested in learning more about computers, I am going to tell you about some basic things regarding a computer.

Computer is an ultra modern electronic device for storing and analysing information fed into it. A computer consists of five major components  the input unit, the output unit, the memory

unit, the control unit and the arithmetic unit. The input unit and the output unit consist of devices that permit a computer to receive or exhibit information. The memory unit, the control unit and the arithmetic unit make up the central processing unit (CPU). This CPU looks like a box. It has a motherboard, the chip, the cards and the RAMs in it. Monitor is another main part of the computer. It works like a TV screen. It shows whatever it is asked to do. Another main part is the keyboard which is just like a typewriter. There is a mouse in the computer. This mouse is a trigonometrical shaped thing that sits by the keyboard. Actually it is called the mouse because of its shape. You can do different things by clicking on the icons with the mouse.

However, every computer has its own machine language. Instruction to the computer must be given in this language since this is the only language that a computer actually understands.

This is all for today. You will know more about it when you begin to use it.

Hope you in sound health and joyful time. With love.

Yours affectionately,

Tahseen
