Answer Key

Computers and tablets on a network

Section A: Quick Questions

A — A laptop

B — True

A — Connect by cable or wireless

B — A computer with a separate screen and keyboard that stays on a desk

A — Laptops and tablets are both devices that can be on a network

Section B: Match the Pairs

network device → A computer, laptop or tablet that joins a network so it can send and receive data

laptop.connect(wifi) → A laptop joins the network wirelessly so it can send and receive data

A tablet can join a network, but only after it is connected → tablet.connect(network)

A desktop computer can join a network using a cable → desktop.plugIn(cable)

tablet.send(photo) // not connected to any network → The tablet is not connected, so it cannot send data. It must join the network first, for example with tablet.connect(network).

network = [desktop, laptop, tablet, pencil] → A pencil is not a network device. Only computers, laptops and tablets can join a network and send or receive data.

Section C: Definitions

network device — A computer, laptop or tablet that joins a network so it can send and receive data. It must be connected by cable or wireless first.

Section D: Fill in the Blanks

connect(tablet, "SchoolWiFi")

IF tablet.connected = true THEN
  send(tablet, "photo.jpg")
END IF

tablet.connect("ClassWiFi")
data ← tablet.receive()
show(data)

IF NOT laptop.connected THEN
  connect(laptop, "HomeWiFi")
END IF

networkDevices ← [desktop, laptop, tablet]

Section E: Spot the Error

B — The comma between the two arguments is missing. It should be connect(device, "wifi") so the laptop connects by wifi before it joins the network.

B — The connection type is text, so it needs quote marks. Without them wifi looks like a variable that does not exist. It should be connect(device, "wifi").

A — A device must be connected to join a network. If connected is false, the IF never runs and the file is never sent. Line 1 should set connected ← true.

A — The text is missing its closing quote mark. It should be device ← "desktop".

C — The variable name is misspelled. The tablet was stored in device, so line 3 should be join(network, device).
