2. Computers NOW SEE MY PRESENTATION My name is KRYSTIAN ZAJDEL. I have lots of different hobbies but my favourite are computers and information technology. Working at a computer for some people is a very boring work but I really like it and it gives me a lot of joy. Of course I dont mean working with office software because I hate it. I learn programmes and create web pages. I really enjoy it when I have time for this. I am also interested in computer networks and telecommunication. Thanks to the computer I can also listen to music, watch movies and surf the Internet. I would like to devote my future life to computers and telecommunication. If it comes true, it will be just great.
