Computer coding concepts explained

Programming Concept

A computer can't perform any work by its own, it must be provided with some instructions, by which it knows what is to be done. Collection of such instructions is called a program. A computer understands only a limited set of instructions, which must be in binary codes.

The communication between two parties whether they are machine or human being always needs a common language or terminology. The language used in the communication among human being is called natural language where as for the communication between human and machine is called programming language. The computer has its own language and any communication with the computer must be in its language or translated into its language.

Programming has changed a lot since the first computers were created. The original programs were very simple and straight forward comparing to today's elaborated databases, word processors and action games.

Different computer language have been created to write these increasingly complex computer programs.
