What is the item that you have to use everyday to work, study, chat and play?
A computer of course! Have you read anything about computer history, if your answer is NO then let me give you a brief evolution of computer

This is ENIAC, the first computer and it is as big as the entire room!

Then there is Altair 8800, a computer that can put on top of your table but it is kind of boring looking at a big electronic box.

This is APPLE II, one of the 1st generation personal computer with a screen.

Its is personal computer that you can bring wherever you want
