Three generations of computer languages are described: 1) Machine and assembly languages (1st and 2nd generation) which use cryptic codes that are translated to machine code. 2) Higher-level languages like FORTRAN, COBOL, BASIC (3rd generation) which use more English-like phrases. 3) Even higher-level languages like Visual Basic and Visual Age (4th generation) which may use graphical tools. 5th generation languages are designed for artificial intelligence problems.

The Evolution of Programming Languages
The Evolution of Programming Languages To build programs, people use languages that are similar to human language. The results are translated into machine code, which computers understand. Programming languages fall into three broad categories: Machine languages Assembly languages Higher-level languages
The Evolution of Programming Languages Machine Language(First Generation) Machine languages (first-generation languages) are the most basic type of computer languages, consisting of strings of numbers the computer's hardware can use.
The Evolution of Programming Languages Assembly Language(Second Generation) Assembly languages (second-generation languages) are only somewhat easier to work with than machine languages. To create programs in assembly language, developers use cryptic English-like phrases to represent strings of numbers. The code is then translated into object code, using a translator called an assembler.
The Evolution of Programming Languages Assembly code Assembler Object code
The Evolution of Programming Languages Higher-Level Languages Higher-level languages are more powerful than assembly language and allow the programmer to work in a more English-like environment. Higher-level programming languages are divided into three "generations," each more powerful than the last: Third-generation languages Fourth-generation languages Fifth-generation languages
The Evolution of Programming Languages Third Generation Language Third-generation languages (3GLs) are the first to use true English-like phrasing, making them easier to use than previous languages. 3GLs are portable, meaning the object code created for one type of system can be translated for use on a different type of system. The following languages are 3GLs: FORTAN C COBOL C++ BASIC Java Pascal
The Evolution of Programming Languages Fourth Generation Language Fourth-generation languages (4GLs) are even easier to use than 3GLs. 4GLs may use a text-based environment (like a 3GL) or may allow the programmer to work in a visual environment, using graphical tools. The following languages are 4GLs: Visual Basic (VB) Visual Age
The Evolution of Programming Languages Fifth Generation Language A fifth generation programming language is a programming language are designed to make the computer solve the problem of you. Fifth generation language are used mainly in artificial intelligence research. Prolog, OPS5 and Mercury are the best known fifth generation languages.
Thank You..
