This document discusses the four generations of computer programming languages: first generation uses binary machine language directly, second generation includes assembly languages that are closer to machine language, third generation comprises high-level languages that are easier for humans to read and write like C and Pascal, and fourth generation languages aim to be even more user-friendly and portable across operating systems. Each generation is associated with advances in computer technology from transistors to integrated chips to microprocessors.

2. Introduction
1. The computer languages are the languages by which
a user command a computer.
2. These languages are divided into four generations :
• First generation language - Machine language
• Second generation language- Assembly language
• Third generation language- High Level Language
• Fourth generation language (4GL)

3. FIRST GENERATION LANGUAGE
• Machine language, binary language and low - level
programming language.
• Used to program the computer system at a very low
level of abstraction.
• In the machine language, a programmer only deals
with a binary number i.e. 0 and 1.

4. SECOND GENERATION LANGUAGE
• Assembly language and also low level programming
language.
• The program written in assembly language is called
source program.
• It is written for only one type of CPU.
• Technology used : TRANSISTORS.

5. THIRD GENERATION LANGUAGE
• Languages like C, Pascal, FORTRAN etc. are called
high level languages.
• Not machine dependent.
• Technology used : INTEGRATED CHIPS [IC].

6. FOURTH GENERATION LANGUAGE
• User - friendly
• Works in any operating system.
• Higher rate of execution.
• Easy access to information for user.
• Technology used: MICROPROCESSOR
