📖 Let Us Begin!

Have you seen a computer at home, school, or a shop? A computer is a machine that helps us do many things — write, draw, play games, watch videos, and learn!

Just like our body has many parts (eyes, ears, hands), a computer also has many parts. Each part has a special job. Let us learn about the main parts of a computer.
