Read the following passage carefully and answer the questions in your own word :
One of the greatest advances on modern technology has been invention of computers. They are used on large scale in industry, education and every aspect of life. They can carry out complex mathematical functions and other types of work because they work accurated at high speeds. They also save research workers years of hard work. This whole process by which machines can be used to work for us has been called automation. Man may not worry that machines will control them. Machines may learn from their performances, but as they have no thinking power, they can only operate with instructions from man.
