Programming Languages Lesson 1

There are four types of programming languages.

1. First generation Programming Languages (Machine Languages)
2. Second Generation Programming Languages (Assembly Languages)
3. Third Generation Programming Languages (High level Languages)
4. Fourth Generation Programming languages (Artificial Languages) 

First Generation Programming Languages (Machine Languages)

• Very Difficult to Understand
• Commands are based on 0 and 1.
• Programmer need to know about the hardware in the computer system.

Second Generation Programming Languages (Assembly Languages)

• Commands are represented by symbolic names (ADD, SUB)
• Depend on machine.
• Programmer needs to know about the hardware of the computer.

Third Generation Programming  Languages(High Level Languages)

• Very easy to understand
• No need to know about the hardware
• Do not depend on machine.

Fourth Generation Programming Languages (Artificial Languages)

• Very easy.
• Close to English
• Can learn Easily.
