Answer Key
LAN and WAN
Section A: Quick Questions
Q1
A — LAN
Q2
B — A WAN connects networks over a large distance
Q3
A — A home LAN
Q4
A — The largest WAN, joining many networks around the world
Q5
B — LANs
Section B: Match the Pairs
Q1
LAN → A network that connects devices in one small area, such as a home or a school
Q2
WAN → A network that connects many LANs across a large distance, such as between cities or countries
Q3
A school's computers, printers and tablets all joined together inside the one school grounds → school_network = LAN
Q4
The internet joins millions of LANs all around the world, making it the largest network of its kind → internet = largest WAN
Q5
home_wifi = WAN → A home Wi-Fi network connects devices in one small area, so it is a LAN, not a WAN. It should be home_wifi = LAN.
Q6
WAN = devices in one classroom → A WAN connects networks over a large distance, not just one classroom. A single classroom network is a LAN.

Q1
A — A LAN covers one small area such as a home or school, so lan_area should be "small". A large area is what a WAN covers.
Q2
A — A WAN joins many LANs, so it should start as an empty list (wan = []). A number has no append() method, so the next lines would fail.
Q3
B — A LAN covers one small area such as a single building. Covering many countries describes a WAN, so it should be "one building".
Q4
B — The internet is the largest WAN, not a LAN. Line 2 should be internet = "WAN".
Q5
C — A small area such as a home or school is a LAN. A WAN covers a large distance, so this should print "LAN".
