A personal computer is a small machine that helps people do many different things like play games, watch videos, do homework, and even talk to their friends and family who are far away.
It has a special "brain" called a CPU that helps it think and do things very fast. It also has a screen so you can see all the things you want to do, and a keyboard and mouse to help you type and click on things.
You can connect your personal computer to the internet so you can look up information and talk to people from all around the world. You can also save your work, pictures, and videos on the computer so you can see them again later.
Sometimes people like to make their personal computer even better by adding more things to it like a special speaker or a camera so they can take pictures or have video chats with their friends.
A personal computer is a very helpful tool that can do many things to make your life easier and more fun!
