    What are Programming Languages

A Programming language is a language specifically designed to express computations that can be performed by the computer. Programming languages are used to create programs that control the behaviour of a system, to express algorithms,or as mode of human-computer communication.

    Programming languages have a vocabulary of syntax and semantics for instructing a computer to perform specific tasks. The term Programming language usually refers to high-level languages, such as BASIC, C, C++,COBOL and FORTAN. Each of these languages has a unique set of keywords and special syntax for organizing program instructions.
While high level Programming lanuages are easy for the humans to read and understand, the computer actually understands the machine language that consists of numbers only. Each different type of CPU has its unique machine language.
Between the machine languages and high-level languages, there is another type of language known as assembly language. Assembly languages are similar to machine languages but they are much easier to program because they allow a programmer to substitute names for numbers.The Programming language are the primary tools for creating software.
