- Read each of the following statements and state the generation of the computer belongs to.
|Guess Who I am||I Belong to|
|1. I can connect to other computers. You can click the icons to make me do many different things.||4th generation computers (1971 – 1980)|
|2. I am big enough to occupy your entire room but you cannot use me to play games.||1st generation computers (1940 – 1956)|
|3. I am of the size of a desk and perform calculations in a fraction of a second.||2rd generation computers (1964 – 1971)|
|4. I come in different sizes. you can put me in your bag and carry me around.||5th generation computers (1980 – present)|
2. Sarita came across pictures of some devices. Help her name the generation of computers each device belongs to.
|Transistor – (2nd generation)|
|Microprocessor – (4th generation)|
|Integrated Chips – (3rd generation)|
3. Usman wants to prepare a timeline to show the inventions that helped in developing computers. Help him fill in the boxes to complete the timeline?
- Different stages in the evolution of computers
- ENIAC, EDVAC First Generation => IBM1401, Honey well 400 => IBM 360, PDP => KENBAK, APPLE => ROBOT (Natural Language Processing)
- Devices used in different generations of computers.
- Punch card, Vaccum tubes => Transistors, Magnetic Tapes => Integrated Circuits => MIcroprocessor, Semi-conductor => Super conductors
