A complete description of a programming language includes the computational model, the syntax and semantics of programs, and the pragmatic considerations that shape the language.

A programming language is used to write computer programs such as

•     Applications

•     Utilities

•     Servers

•     Systems Programs

A program is written as a series of human understandable computer instructions that can be read by a compiler and linker, and translated into machine code so that a computer can understand and run it.

A programming language is a vocabulary and set of grammatical rules for instructing a computer to perform specific tasks. Each language has a unique set of keywords (words that it understands) and a special syntax for organizing program instructions.

A programming language is an artificial language designed to express computations that can be performed by a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine, to express algorithms precisely, or as a mode of human communication.

People program to create software, which can take many forms such as spreadsheet applications, Web applets, operating systems or corporate transaction databases.

Software consists of a series of instructions that tells hardware (or another piece of software) to perform one or more actions. The programming language is the set of syntax used to create those instructions and the rules associated with their usage.

A language used to write instructions for the computer. It lets the programmer express data processing in a symbolic manner without regard to machine-specific details.
