Answer Key

Wireless access point

Section A: Quick Questions

A — Lets wireless devices join a wired network

B — By a cable to the wired network

B — Add a wireless access point near that corner

A — More access points can cover a bigger area

A — The name of a Wi-Fi network

Section B: Match the Pairs

wireless access point → A device that connects to a wired network and broadcasts a Wi-Fi signal so wireless devices can join

SSID → The network name that a wireless access point broadcasts so devices can find and choose the Wi-Fi network

An access point is plugged into the wired network with a cable and then shares it over Wi-Fi → cable -> access point -> Wi-Fi

Adding another access point in a far corner of a building extends Wi-Fi coverage → access point 1 + access point 2 = more Wi-Fi coverage

A wireless access point is the same thing as a router, so every network needs both to do exactly the same job. → An access point only provides the Wi-Fi connection to a wired network, while a router also directs data between different networks, such as to the internet.

Wi-Fi devices find the network by looking for the access point's IP address in the Wi-Fi list. → Devices find a Wi-Fi network by its network name (SSID), not by an IP address, which is shown in the Wi-Fi list.

Section C: Definitions

wireless access point — A device that connects to a wired network and broadcasts a Wi-Fi signal so wireless devices can join the network.

Section D: Fill in the Blanks

wireless access point broadcasts Wi-Fi

SSID = network name

Access point plugs into a wired network

Wi-Fi coverage = area the signal reaches

A router directs data between networks

Section E: Spot the Error

B — A wireless access point connects to a wired network, not to mobile data. The line should be links_to = "wired network".

A — The network name (SSID) is text, so it must be in quotes. The line should be ssid = "HomeWiFi".

D — The device is 20 m away and the coverage is 30 m, so it is inside the Wi-Fi coverage. It should print "Wi-Fi connected".

B — Routing data is the router's job. An access point broadcasts the Wi-Fi signal. The line should be ap_job = "broadcast Wi-Fi".

D — There is a comma missing between "joins" and ssid. The line should be print(d, "joins", ssid).
