The computer performs simple and fast calculations under the control of a set of instructions called a program. The programs are usually stored within, and processed by, the computer. The calculation results which are sent to output devices, such as monitors or printers, are mechanically precise. Because of its extraordinary speed and accuracy, the computer finds applica-tion in a wide range of activities in business, industry, and scientific research.
