Answer Key

Wired vs wireless: mobility and convenience

Section A: Quick Questions

A — A tablet using Wi-Fi

B — The cable must reach a fixed connection point

A — Wireless devices can move around while staying connected

B — Join the Wi-Fi network with the password

A — A cable and a free port to plug into

Section B: Match the Pairs

connect(phone, wifi) → A phone joins the network wirelessly, so it can be carried around and still stay connected while in range.

plug(desktop, wall_port) → A desktop computer connects with a cable to a fixed point, so it stays close to that port.

Adding a new wireless device is easy: choose the network and enter the password. → join(tablet, 'HomeWiFi', password)

Adding a new wired device needs a free port and a cable. → if free_port: plug(cable, newPC)

desktop.moveToRoom() // still online with cable unplugged → A wired desktop loses its connection when it leaves the cable. It is tied to a fixed connection point.

tablet.join(network) // needs a cable and port → A tablet joins wirelessly, so it does not need a cable or a port.

Section C: Definitions

mobility — Wireless devices like phones and tablets can move around and join a network easily, while wired devices like desktop computers are tied to a fixed cable connection point.

Section D: Fill in the Blanks

phone.connection ← "wireless"
phone.canMove ← true

desktop.connection ← "wired"
desktop.canMove ← false

IF device.canMove = false THEN
  device.connection ← "wired"
ENDIF

IF tablet.needsCable = false THEN
  OUTPUT "Join the Wi-Fi"
ENDIF

desktop.needsCable ← true
OUTPUT "Plug into a port"

Section E: Spot the Error

A — Phones and tablets join a network wirelessly, so phone_link should be "wireless". A wired link would tie the phone to a cable, and the message that follows would then be wrong.

C — A wired desktop computer needs a cable plugged into a fixed connection point, so it cannot roam anywhere. The message should say it is tied to a socket.

B — A wireless tablet does not need a cable to join a network. needs_cable should be False.

B — A for loop header must end with a colon. It should be: for d in devices:

D — A new wireless device is added by choosing the Wi-Fi network and entering the password, not by plugging in a cable. It should print "Enter Wi-Fi password".
