Quick Questions

Shade in the A or B circle for each question.

1. Which best describes a computer network?

A A single computer with lots of storage

B A group of digital systems connected so they can share data

2. In a network, what is each connected device called?

A A node

B A cable

3. A school has 20 laptops connected so students can save work to one shared folder. Is this a network?

A Yes, the laptops are connected to share files

B No, because the laptops are all in the same room

4. Which is a benefit of connecting computers in a network?

A Every device needs its own printer

B Several devices can share one printer

5. Which statement about sharing an internet connection is true?

A Many devices on a network can use one internet connection

B Only one device on a network can use the internet at a time

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1network		AAny single device connected to a network, such as a laptop, tablet or printer
2node		BA group of digital systems connected together so they can share data
3Computers on a network can share a printer so anyone connected can print to it		CA node is a single connected device, not the whole network. It should be something like node = "laptop".
4Devices on a network can share one internet connection so they can all go online		Dnetwork.share("printer")
5network = [laptop]		EA network needs at least two connected digital systems, so one laptop on its own is not a network. Add another node, like [laptop, printer].
6node = "the whole network"		Fnetwork.share("internet")

Answer Key

Computer network

Section A: Quick Questions

B — A group of digital systems connected so they can share data

A — A node

A — Yes, the laptops are connected to share files

B — Several devices can share one printer

A — Many devices on a network can use one internet connection

Section B: Match the Pairs

network → A group of digital systems connected together so they can share data

node → Any single device connected to a network, such as a laptop, tablet or printer

Computers on a network can share a printer so anyone connected can print to it → network.share("printer")

Devices on a network can share one internet connection so they can all go online → network.share("internet")

network = [laptop] → A network needs at least two connected digital systems, so one laptop on its own is not a network. Add another node, like [laptop, printer].

node = "the whole network" → A node is a single connected device, not the whole network. It should be something like node = "laptop".

Section C: Definitions

network — A group of digital systems connected together so they can share data, files, printers and an internet connection. Each connected device is called a node.

Section D: Fill in the Blanks

network = ["laptop", "tablet", "printer"]
print(len(network))

network = ["laptop", "tablet", "printer"]
for node in network:
    print(node)

network.share("printer")

network = ["laptop", "router"]
if "router" in network:
    share_internet = True

network.share("internet")

Section E: Spot the Error

B — The closing bracket is missing. It should be nodes.append('printer') so the printer is added as a new node on the network.

B — An if statement needs a colon at the end. It should be if devices >= 2: so the network message prints when 2 or more devices are connected.

D — The queue holds only one print job, at index 0. Index 1 does not exist. It should be queue[0] so the shared printer receives the job.

B — A single = assigns a value. To compare in an if statement, use ==. It should be if connected == True: to check the shared connection is on.

C — The variable is called file, and photo is not defined. It should be shared.append(file) so the file is added to the shared list.
