HOW DO COMPUTERS WORK?

A computer is a machine that can be programmed with instructions. Computers receive information (input), they carry out a process and they produce output.
HISTORY OF COMPUTERS: The first computer was invented in 1943. It was used to break the codes used by the German army to send messages during World War II. It's name was Colossus because it occupied a whole room.

HOW HAVE INVENTIONS CHANGED ART AND MUSIC?

Many artists now use computer software to produce their work. Musicians digitalise music, so they can change the pitch and tone of the music by using modern technology. Digital recording makes it possible to mix different tracks to produce a new version of as ong. Instruments can be added or removed from the recording.
