Programming language is a vital and essential part of computers. Even though you do not actually see these languages, they are the bases and make up of software programs. Software is essential to a computer because without software, a computer can do nothing. All of the software that we use to make our computers useful is created by individuals known as programmers; these programmers use different types of programming languages to develop software programs. The first primitive programming language was actually created for the invention of the ‘difference engine’. This invention created in 1822 by Charles Babbage was a mechanical calculator that would tabulate polynomial functions. A few of the popular programming languages created in the 1970’s include SQL, PASCAL,C, ADA, SASL. The SQL language was developed in the early 70’s at IBM by Donald Chamberlin and Raymond Royce. SQL is a database computer language designed for managing data in relational database management systems. PASCAL was actually designed in 1969, but it was published in 1970 by NikLaus Wirth. PASCAL is an influential imperative and procedural programming language, and it was intended to encourage good programming practices using structured programming and data structuring. C is a programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system. Although C was designed for implementing system software; it is also used for developing portable application software. The Ada programming language was created in the early 1970s primarily for applications used by the U. S. Department of Defense. The language is named after Countess Ada Lovelace, an influential and historical figure in the field of computing. Some of the programming languages that were designed in the 1980’s are C++, Postscript, Eiffel, and Caml. C++ is a general-purpose programming language. It was developed by Bjarne Stroustrup starting in 1979 at Bell Labs as an enhancement to C programming language and originally named C with Classes. It was renamed C++ in 1983. PostScript is a language created in 1982 by John Warnock. It is best known for its use as a page description language in electronic and desktop publishing. Eiffel is an iso standardized programming language developed by Bertrand Meyer in 1986. The purpose of Eiffel was to make the code more readable, and to allow programmers to concentrate on the important aspects of a program without getting bogged down in implementation details. Eiffel's simplicity is intended to promote simple, extensible, reusable, and reliable answers to computing problems. Caml is a general-purpose programming language. It was developed by INRIA in 1985. The popular programming languages that were developed in the 1990’s include Java, Visual Basics, Python, Ruby, and JavaScript (Cmm). Java is a programming language developed by James Gosling in 1995 as a core component of Sun Microsystems (Oracle Corporation) Java platform. Java applications are typically compiled to bytecode that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Visual Basics is the third-generation event-driven programming language and integrated development environment (IDE) from Microsoft for its COM programming model. This language was developed in 1998. Python is a general purpose high- level programming language. It was designed in the late 1980’s and implemented in early 1990 by Guido Von Rossom. Its design emphasizes on code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in other languages. Ruby is a, general purpose programming language, developed in 1993 by Yukihiro Matsumoto. It was designed for programmer productivity and fun, following the principles of good user interface design. JavaScript was created by Brendan Eich. It is most commonly used as part of web browsers, whose implementations allow client-side scripts to control the browser, and alter the document content that is displayed. It is also being used in server-side programming, game development and the creation of desktop and mobile applications. Some programming languages that were developed in the 2000’s include C#, ActionScript, Java 2, and V6.net. C# was created by a team of programmers led by Anders Hejlsberg. C♯ is intended to be a simple, modern, general-purpose, object-oriented programming language. ActionScript was developed by Macromedia inc, and was ActionScript was initially designed for controlling simple 2D vector animations made in Adobe Flash. Initially focused on animation, early versions of Flash content offered few interactivity features and thus had very limited scripting capability. Java 2 is the predecessor to java, and V6.net is the predecessor to Visual Basic.
