During the last decade, the computer has become an indispensable tool of business, industry, and scientific research in performing tasks whose treatment would be ilnpossible without it. The computer is an automaton that executes computational processes according to precisely specified rules. It usually possesses only a limited repertoire of elementary instructions that it "understands" and is capable of obeying, but these instructions are executed with tremendous expediency and reliability. The essence of the computer's power and wide applicability lies in its ability to execute extremely long sequences of instructions containing an almost infinite combination of elementary actions. The act of incorporating such instruction sequences into "recipes" representing certain classes of computational processes is called programming. But the fundamental ideas behind designing programs can be explained and understood without any reference to the computer.
