1st Generation (programming language)

>A machine-level programming language
>No translator was used to compile
>Programming Instructions were entered through front panel switches of computer system
>Main Benefit is that a code written by a user can run very fast,efficiently,and directly executed by the CPU

MACHINE LANGUAGE
>More difficult to learn than higher generations programming languages
and to edit if errors occur

2nd Generation (programming language)

>A programmer can read and write codes
>Must be converted into a machine readable form,a process called assembly to run it
>The language is specific to a particular processor family and environment

3rd Generation (programming language)/High-level language
>Refinements are made to make the languages more programmer-friendly
>Introducted in the late 1950's,early examples are Fortran,ALGOL,and COBOL
>C,C++,C#,Java,BASIC,and Delphi,the most popular general-purpose languages today
>It supports structured programming
