CONTENT OF THE LESSON 

INTRODUCTION 

Each new computer was better than the one before it. Each new type of computer is therefore known as a generation of computers.

Computer are classified according to generation, the following types of computers can be identified as follows –

FIRST GENERATION 

First generation computers are the first computer. They used vacuum tubes. First generation needed much electricity before they could be used.

They are slow and can only store little information.

SECOND GENERATION 

Second generation is the second computer made. Just like the first generation, it is big, cost and slow. But it is faster and can store more information than the first generation computers.

First generation used transistors. And needed less electricity.

 

THIRD GENERATION 

Third generation computer is the third computer made. They contained integrated circuits that allow flow of electricity.

Third generation computers are cheaper, smaller and faster than the second generation computers. They store more information than first and second generation.

 

FOURTH GENERATION 

Fourth generation computer is the four computer made. They contained microprocessors that’s large – scale integrated circuits that allow more flow of electricity than third generation.

Fourth generation computers are cheaper, smaller and faster than the third generation computers. They store more information than first, second and third generation.

 

FIFTH GENERATION 

Fifth generation are work in progress. They are to contain artificial intelligence.

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Shows the pupils chart showing different computer generation.

Pupil’s Activities – Look at the chart and describe the difference.

3. Discusses the computer generation.

Pupil’s Activities – Different the different between computer generation.

CONCLUSION

• To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

• Next Lesson – Classification of Computer by Purpose (Primary 5)
