What is the distinguishing difference between a LAN and WAN?

Question

Options

• AA LAN is a group of networked computers within a confined geographic area.
• BA WAN is a group of networked computers within a confined geographic area.
• CA LAN typically provides slower network connection speeds than a WAN.
• DA WAN is commonly used for intra-office communication.

• C

• D

Explanation

Option A correctly defines a LAN (Local Area Network) as computers networked within a confined geographic area - like a home, office, or school building - which is the fundamental characteristic that distinguishes it from a WAN. Option B has this backwards: it's the WAN (Wide Area Network) that spans large, dispersed geographic areas like cities, countries, or the entire internet. Option C is the opposite of reality - LANs are typically faster than WANs because the physical distance between devices is short and the infrastructure is dedicated. Option D is also reversed - intra-office communication is precisely the use case for a LAN, not a WAN.

Memory tip: Think of the letters - LAN = Local (small/close), WAN = Wide (big/far). The internet itself is the world's largest WAN.
