Computing

From Academic Kids

Originally, the word computing was synonymous with counting and calculating, and a computer was a person who computes. Since the advent of the electronic computer, it has come to also mean the operation and usage of these machines, the electrical processes carried out within the computer hardware itself. It does not denote the theoretical concepts of creating programs to run on the computers themselves, though there is a subset of computer science that deals with the original sense of computing mathematical calculations.
