  1. Read each of the following statements and state the generation of the computer belongs to.
Guess Who I amI 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?

  1. Different stages in the evolution of computers
    1. ENIAC, EDVAC First Generation => IBM1401, Honey well 400 => IBM 360, PDP => KENBAK, APPLE => ROBOT (Natural Language Processing)
  2. Devices used in different generations of computers.
    1. Punch card, Vaccum tubes => Transistors, Magnetic Tapes => Integrated Circuits => MIcroprocessor, Semi-conductor => Super conductors

4. Write two major characteristics of each of the following computers:

1. Robot1. Smaller, cheaper, faster and more reliable
2. Parallel processors
2. EDVAC1. Built using approximately 18,000 vacuum tubes.
2. Occupied extensive space.
3. KENBAK1. Smaller, lighter, more powerful, and reliable.
2. Could be connected to other computers to exchange information.
4. IBM 14011. Built using transistors and magnetic tapes.
2. Used assembly language.
5. IBM 3601. Integrated circuits (ICs) were used in the CPU.
2. Smaller in size and could be placed on a desk.
