What do I learn about Computer?

The first thing that I learned in computer is the importance of it in our daily life. And it can communicate with other devices. And how to shop on line so that we can save our time to buy something that we want in fastest way. But one lesson in computer that very hard for is number system because I don't understand some solution for that but now I know to solve that. Ive learned also on how to type in a faster way. And the last lesson that I learn in computer is making a blog and it enjoy because having a blog is also having a friends.
