Computers come in all shapes and sizes, from the tiny computers embedded in our phones to the massive supercomputers used by governments and scientific organizations. But despite their differences, all computers share some basic characteristics. They are all electronic devices that can store, process and output data.

Most computers can be classified according to three criteria: size, generation and type.

Size: Computers can be classified according to size, from the smallest handheld devices to the largest supercomputers.

Generation: Computers can also be classified according to generation. The first generation of computers used vacuum tubes and were large, expensive and unreliable. The second generation of computers used transistors and were smaller, cheaper and more reliable. The third generation of computers used integrated circuits and were even smaller, cheaper and more reliable. The fourth generation of computers used microprocessors and are the computers we use today.

Type: Finally, computers can be classified according to type. Some common types of computers include desktop computers, laptop computers, tablet computers, smartphones and wearable computers.

Computers have come a long way since the early days of vacuum tubes and transistors. Today’s computers are smaller, cheaper and more powerful than ever before. Thanks to their versatility, speed and storage capacity, computers have become an essential part of our lives.



1. How have computer generations changed the ways we use computers?
2. What trends have you noticed in the way younger people use computers?
3. Do you think future computer generations will continue to change how we use them? If so, how?
4. What implications do generational changes in computing have for society as a whole?

2. What are the three types of computers and what do they do?
3. How are the three types of computers different from each other?
4. What is your favorite type of computer and why?
5. Do you think everyone should use the same type of computer?


The class teacher wraps up or concludes the lesson by giving out a short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she makes the necessary corrections when and where the needs arise.








  1. Write a BASIC program to find the average of five numbers.
  2. Write short notes on the program terminator.
  3. Explain the following: Character set, constants and variables.
