What I want to learn about COMPUTER!!

Computers were not kind of my familiar areas.
Today, people can talk whenever and wherever. They can feel “We can be always connected with someone,” Because people, I am also one of them, got convenience and great pleasure, I do not care so much like public opinion that technology effects on society badly. On the other hand, I tend not to rely on progress pf technology too much. For example, I want Polaroid camera or single-lens reflex camera compared with digital camera. I have a longing for sending letters compared with mails.
What I want to learn is many possible things by computers. I believe that they might be joyful for every human being. Recently, I found a site that I can draw a picture and exchange it with someone who is chosen at random by the computer in the world. It is a wonderful example that computer makes it possible. Then, when I go to Africa someday, I want to show many things in the world to children and make people in these countries to experience with children.
Of course I want to learn about and be able to use Power Point because I heard that I need to use them when I will give presentation!! I really feel nervous for my poorness.However, I am full of hope because this class is interesting thanks to Mr. Poza now.
