Class 7 Computer Science — Kinds of network

Tell a network that covers one site from one that stretches between towns, and say what joined-up computers can do that separate ones cannot.

Name: ________________________

  1. 1.A wide area network joins a company's offices in Delhi and Chennai. What kind of network is the one joining the machines inside the Delhi office itself?

    • a) It is not really a network
    • b) A local area network
    • c) A second wide area network
    • d) It is the same network under another name

  2. 2.A school joins its lab to the outside world through one connection. A pupil says each computer in the lab therefore has its own separate line out. Are they right?

    • a) Yes — every computer is given a line of its own
    • b) No — the whole lab shares the one connection
    • c) Yes, but only while the lab is quiet
    • d) No — none of the computers can reach the outside at all

  3. 3.Two computers are joined by a single cable and can pass files to each other. Is that a network?

    • a) Yes — two joined machines are already a network
    • b) No — a network needs at least ten machines
    • c) Only if one of the two is switched off
    • d) No — a network has to reach another town

  4. 4.Fifteen computers in a lab share one printer, one scanner and one connection out of the building. How many of those three things would each computer need if the lab had no network?

    • a) Only the connection out
    • b) Only the printer
    • c) All three of them
    • d) None of them

  5. 5.Which of these can a computer that is joined to nothing at all still do?

    • a) Add up a column of numbers by itself
    • b) Send a message to the room upstairs
    • c) Print on the machine down the corridor
    • d) Open a file kept on the machine next to it

  6. 6.A network that stretches between towns or countries is called a wide area network. What are the three letters it is usually shortened to?

  7. 7.Twenty computers in a lab all print on the same shared printer over the network. How many printers does the lab need?

  8. 8.Match each network to how far it reaches.

    • The computers in one school lab
    • The computers across a whole college site
    • A bank's branches in four cities
    • The machinery joining continent to continent
    • A whole country
    • One site with several buildings
    • The whole world
    • A single room
