Holy crap.
Computers are used for anything and everything: They are used to monitor patients during surgery, for doing complicated mathematical analysis of data, for running traffic control centres in airports, for routing trains across countries, tracking shipments across countries and the world, tracking sales in a store and controlling inventory, for routing phone calls, for game platforms like the XBOX or PS3, for choosing and arranging the order of songs on a radio stations playlist, to coordinate and track space flights, for monitoring and maintaining the GPS satellite location system.
There are very few things that computers are not used for in modern daily life.
