Computers form an inevitable part of modern human lives.

Computers ranging from mainframes to smartphones are in use

today. Ever since the advent of programmable computers, a

number of programming languages have come. In simple terms,

a programming language gives instructions to the computer. A

programming language has a syntax and semantics. Unlike

machine codes or assembly language, a high-level language can

be easily understood just like a communication language.

Different languages have different purposes. While some are

used to program huge mainframe computers, some are

object-oriented and yet some others are scripting languages,

mostly used in connection with the web. From FORTRAN to

Swift, computer programming has evolved a lot over the years.

Open sourcing has led to the development of a number of

languages after 1990. The newest ones lay great importance to

mobility, distribution, reliability and security.
