  • It is a wonderful electronic machine.
  • It works very fast, never makes mistakes, never gets tired and can remember and store a lot of information.
  • It works on the principle of taking input (data entered in the computer), processing it using some programs and then delivering the output (the result produced based on the user input). It means first some data is entered in the computer. Then this data is processed with the help of some programs and finally output is delivered. Output here refers to result.
  • It makes our work easier and helps us to do many things such as calculations, writing letters, playing games, watching movies, listening to music, drawing, sending messages and even shopping by using the Internet.
  • It cannot think on its own or make decisions. It only follows the instructions given to it.
