First generation languages (1GL): Also called Machine level programming language consists only of 0s and 1s. Since in that time no compiler or interpretors were developed it was restricted to binary language. Difficult to learn but fastest and more effecient than most modern languages.
Second generation languages (2GL): Also called Assembly language since its using assembler to translate mnemonics used to specify many instructions. Difficult but easier to develop programs than 1GL language. It needs some specific hardware and environment. Still that was inefficient to write large applications.
Third generation language (3GL): This was design for being more human friendly by using keywords like if, else, repeat etc. Python as 34 keywords. First language was FORTRAN followed by ALGOL and COBOL released in almost same time in late 1950s. Some modern 3GL languages are BASIC, C, C++.
Fourth generation lanuages (4GL): This is the closer to natural language programming language than 3GL. They are non procedural in nature i.e. programmers just need to specify WHAT to be done than HOW its to be done. This is to reduce programming efforts, development time and software development cost. Most popular example of this is SQL which is query language used for database and MS Access. Here Python also exists.
Fifth generation languages (5GL): Similar to 4GL but only difference is 4GL is used for specific problems/purposes like SQL for DBMS only while 5GL are used to make computers solve problems for you. In 3GL certain algorithms are used to solve problems but in 5GL only conditions are needed to solve the problems. Specify what you want and conditions to be met and computer will solve the problems for you. Some famous examples are Prolog, OPS5 and Mercury
