Computer idiot!

I am not a computer expert. I just can use some basic functions of computer. For example, Word, Excel, E-mail and so on. I can't solve the problems on my computer. What's worse, I just learned how to use Power point a few weeks ago. It's really funny, right? I even didn't know what is URL and how to use BBS. I called my classmates and asked her. It's really a stupid question. In a word, I have so many things to learn about computer. I hope I would become familiar with computer in these four years!
