ComputingFrom Wikipedia, the free encyclopedia.
Originally, the word computing was synonymous with counting and calculating, and a science that deals with the original sense of computing mathematical calculations. "Computing" has come to mean the operation and usage of computing machines, the electrical processes carried out within the computing hardware itself, and the theoretical concepts governing them (computer science). The following definition of computing is given in the ACM report Computing As a Discipline:
