What are the 5 generations of programming languages?

 What are the 5 generations of programming languages?

A computer only understand binary language i.e., 0 and 1.  Programming languages are classified into two types: Low level languages and High level languages.  The first computer language developed by programmers was very complex. Nowadays, with the advancement in computer technology, the languages have also evolved. They have now  become similar to  English language and can be understood by us.

Generation of  languages

1. First generation languages (1GLs):

First generation languages are  called machine language. Machine language is a set of instructions written in binary form i.e. in a string of  0's and 1's. This language is very lengthy and complicated. The machine language is also different for every system. It is written only by experts as it requires much knowledge of the internal computer architecture which is different for different machine. As this language is very complex and understand only by experts, so this language never became popular among users.




2. Second generation languages (2GLs):

Second generation languages are called Assembly language. Assembly  language is a low level language. This language allows the programmer to use symbolic codes called mnemonics instead of numbers. This language also required complete knowledge of  the internal computer architecture. So, this language is also a machine dependent language. As compared to machine language the number of errors in coding was reduced. The assembler required a lot of memory space, thus this language is not suitable for small capacity computers.

3. Third generation languages (3GLs):

Third generation languages are called high level languages. High level language instructions written in english language so it is easy to write and understand. It is formed with the help of variables, arrays and complex arithemetic or boolean expressions. High level languages are  machine independent language.
C, C++, Cobol, Fortran etc are the examples of high level languages.




4. Fourth generation languages (4GLs):

Fourth generation languages are also called high level languages. The fourth level languages are non-procedural programming language.  They are used for the development of commericial  business software.  Java, Visual basic etc are the examples of fourth generation languages.

5. Fifth generation languages (5GLs):

Fifth generation languages are called Artifical intelligence languages.  A fifth generation languages is a graphical development interface which is used to create source languages that are usually compiled with a 3rd generation language or fourth generation language compiler. Artificial intelligence are still in the development process. Voice recognition is the best example of  AI.





 In future it is also possible  with the help of AI,  humans can made there clone robots. Tesla like cars are also made with the help of such kind of technology.

History of computers? Types of computers ?

 History of computers? Computers are not  the creation of one day, it took a long period for the development of modern computer. Charles Babbage is known as the father of computer. Alan Turing is known as the father of modern computer.The 1st computer architecture was introduced by John Von Neumann in 1948. ENIAC was the world's 1st successful electronic computer which was developed by the two scientists namely JP Eckert & Jw Mauchy. It was the beginning of   1st generation computer. Siddhartha was the 1st computer developed in INDIA. The worlds 1st computer called the Z1, was invented by Konrad zuse. CRAY-1 was the 1st Super computer introduced by Seymour R Cray in 1976. PARAM was the 1st supercomputer developed in INDIA In 1990 which is assembled in Pune(Maharashtra). PARAM YUVA II developed in India (Pune). It is performed at a peak of 524 teraflops. It has been ranked 33rd in the list of Top 500 super computers in world. Tianhe-2 is the world's fastest superc...
