Computer algorithms

The word algorithm comes from the name of a Persian author, Abu Ja'far Mohammed ibn Musa al Khowarizmi(c.825 A.D.), who wrote a textbook on mathematics. This word has taken on a special significance in computer science, where "algorithm" has come to refer to a method that can be used by a computer avin for the solution of a problem. This is what makes algorithm different from words such as process, technique, or method. DEFINITION: An algorithm is a finite set of instructions that, if followed, accomplishes a particular task. An algorithm is composed of a finite set of steps, each of which may require one or more operations. The possibility of a computer carrying out these operations necessitates that certain constraints be placed on the type of operations an algorithm can include.
