Answer Key
Wi-Fi
Section A: Quick Questions
Q1
B — Radio waves
Q2
B — It lets a laptop join a network without a cable
Q3
A — The password
Q4
A — 2.4 GHz and 5 GHz
Q5
A — A router or access point
Section B: Match the Pairs
Q1
SSID = "HomeWiFi" → The network name a device looks for and picks when joining a Wi-Fi network
Q2
band = "5 GHz" → A Wi-Fi radio band that is usually faster but covers a shorter distance than 2.4 GHz
Q3
Wi-Fi sends data between a device and a router using radio waves instead of cables → connection = "radio waves"
Q4
To join a Wi-Fi network, a device needs the network name and the correct password → join("HomeWiFi", password)
Q5
Wi-Fi connects devices using a network cable → Wi-Fi is wireless. It uses radio waves, not a cable, to connect devices to the router or access point.
Q6
band = "3 GHz" → Wi-Fi uses the 2.4 GHz or 5 GHz band. There is no 3 GHz Wi-Fi band in this topic.
Section C: Definitions
Q1
Wi-Fi — A wireless network technology that uses radio waves to connect devices to a router or access point, usually by joining a network name and password on the 2.4 GHz or 5 GHz band.Section D: Fill in the Blanks

Q1
C — Wi-Fi sends data using radio waves, not sound waves. The line should be signal = 'radio waves'.
Q2
C — The 5 GHz band is usually faster than 2.4 GHz, but it has a shorter range. The line should be speed = 'faster'.
Q3
D — To join a secured Wi-Fi network you need the network name and the password. The line should be join(name, password).
Q4
B — Wi-Fi is wireless, so the laptop connects to the router using radio waves, not by plugging in a cable. The line should be laptop.connect_to(router).
Q5
A — Wi-Fi is a wireless network technology, not a wired one. The line should be wifi = 'wireless network'.
