In hospitals, most of the equipments use or are run by computers. Look at space exploration; it was all made possible with the advent of computer technology. In the job sector, many of the jobs require knowledge in computers because they mostly involve the use of computers.
The early computers were not that small as those used today and they were commonly used to help in working out complex calculations in mathematics that proved tedious to be done manually. This is why the first machine was called by some as a calculator and others as a computer because it was used for making calculations.
