Computers can be used to shorten the time of a particular task; this can be done because the computer is more faster and can process more information than a normal team of humans in the same period of time. A good example is that scientists have analysed every gene in the human body using a specially developed computer system in the short period of three years rather than the predicted period of hundreds of years by hand.

The programme editors decide what to use to portray the right image. ...read more.
