LANGUAGES:
 
A programming language or computer language is a standardized communication technique for expressing instructions to a computer. It is a set of syntactic and semantic rules used to define computer programs. A language enables a programmer to precisely specify what data a computer will act upon, how these data will be stored/transmitted, and precisely what actions to take under various circumstances. Each programming language can be thought of as a set of formal specifications concerning syntax, vocabulary, and meaning. Certain programs can access the memory location of the hard disk to ensure security to a system. Programming languages are important tools for helping software engineers write better programs faster.
