What are the Generations of Programming Languages

First Generation – 1GL:

Machine code and Assemblers

The first generation of programming languages ​​consisted entirely of a sequence of 0s and 1s that the computer controls interpret as instructions, electrically.

They represent the first programming languages ​​that the computer could understand, they are known as machine language.

Second Generation – 2GL:

Early high-level, unstructured languages ​​– Fortran, Cobol, Basic

The second generation of programming languages ​​consisted of assembly languages. An assembly language converts the sequences of 0s and 1s to a language understood by human beings, such as “add”, “add”, etc.

Code written in assembly language is converted to machine language (1GL).

Third Generation – 3GL:

Structured languages: Algol, Pascal, C, ADA.

Specific Languages: Lisp, Prolog, Smalltalk

The third generation of programming languages ​​is known as high-level languages. A high-level language has grammar and syntax similar to the words in a sentence. A compiler is responsible for translating the high-level language into assembly language or machine code.

All software programming languages ​​need to be translated into machine code for a computer to use the instructions they contain.

Fourth generation (4GL)

Declarative Languages: SQL Application Builders, CASE Tools

Visual Programming: Visual Basic, Visual C

Object Oriented Languages ​​C++, Java, Eiffel

The fourth generation of programming languages ​​advances in the syntax used. 4GL languages ​​are typically used to access databases.

Fifth generation (5GL)

Imitation of the human mind

The fifth generation of programming languages ​​is used for neural networks. A neural network is a form of artificial intelligence that tries to mimic the human mind.
