Ans:- Digital
computers were invented for performing long, time consuming scientific
calculation quickly. Today’s fast computers can create and display virtual
reality scenarios on the computer monitor. Scientists use simulations to test
scientific theories’ as well as to perform risky experiment’s, such as those
involving explosive or toxic materials. A flight simulator is now invariably
used to teach trainee pilots various controls of an aeroplane. This allows the
trainee to practise all the controls under normal as well as emergency
situation before actually flying a plane, thus minimising the risk of loss of
life and property.
Simulations of surgical procedure allow medical students to
learn and practise a surgery, and its intricacies and risks, without dangering
a patient’s life. Another use of
computer simulations in medicine is for testing a new drug before it can be
allowed to be used for humans. The
earlier practise of using animals for drug testing is now banned because of
ethical implications.
