What did the first computer look like?
According to me what I think is you can copy this below given Link in Address bar to know more about ENIAC (world's first computer with a Video Clipping)
It is possible to argue that Charles Babbage's Difference Engine was perhaps the first computer (though it was mechanical not electronic, see: http://www.answers.com/topic/difference-engine?cat=technology
Possibly the first successful programmable (by wiring), electronic, computer was the Colossus Computer built in Bletchley Park
Roughly like the photo above of the recreation of the Atanasoff Berry Computer, the first electronic digital computer (it was not programmable). The first programmable electronic digital computers were significantly bigger.
you look at the first letter of the words you have and go by the alphabet . example your words are art music computer. the alpabetic order is art computer and finally music . that is how you put things in alphabetic order if all of the first letters are the same then you look at the second letter, you look at it like the alphabet and go by that. hopefully this helped you.
Computer viruses are simply computer programs, so they don't really have any physical appearance. You could say that they look like a long string of ones and zeros, or that they look like code. Some viruses may appear on your computer screen disguised as a game or other program - these viruses are called Trojans.
