i want to know stuff about computers an ting.
basically any mention of the following terms/phrases prompts me, in varying degrees, to draw a blank:
- Java
- HTML
- torrent
- file compression
- how much memory has your computer got?
- how fast is your internet connection?
- megahertz

is there a book i can read? basically like a GCSE/A level computer science textbook but something that will be interesting to read. anything?
