There are various kinds of computers like pocket computers, laptops, personal computers, etc.

Also there are various colours and sizes of computer. I too have a computer at home, which has a keyboard, a mouse, a CPU (the brain of computer), a screen or monitor and a UPS.

Computer is a very helpful device. We can learn many new things through Internet and can also do our work easily and quickly on computer.
