Common Network Types for A+
Short answer
Classification relies on scope and intent: PAN is for a person's devices at very short range; LAN/WLAN are local to a building or campus; WAN spans sites or uses carrier links. Use the scenario's described devices and geographic reach to choose the correct category.
Why it appears on the exam
- Classification: Given a brief scenario, select PAN/LAN/WLAN/WAN. - Distinction: Explain why a remote intersite link is WAN rather than LAN. - Context clue questions using physical medium or geographic scope.
Key concepts
Concept 1
Required terms
PAN: Personal Area Network: very short-range network for a single person's devices, typically Bluetooth or similar. LAN: Local Area Network: wired network within a limited area like a home or office. WLAN: Wireless Local Area Network: a wireless network serving a limited location (home, office) typically using Wi-Fi. WAN: Wide Area Network: network connectivity across larger geographic distances, often connecting sites or using carrier links.
Example
A smartphone pairing to wireless earbuds -> PAN.

How Common Network Types works
Classification relies on scope and intent: PAN is for a person's devices at very short range; LAN/WLAN are local to a building or campus; WAN spans sites or uses carrier links. Use the scenario's described devices and geographic reach to choose the correct category.
Example
Multiple wired desktop PCs and a switch inside one office -> LAN.
Concept 3
Common confusion
Learners sometimes misuse LAN vs WAN when the scenario simply mentions internet access: internet access at one site is not itself a WAN. Also, PAN and WLAN may overlap superficially - focus on personal short-range vs shared local Wi-Fi coverage.
Example
Several access points serving office wireless clients -> WLAN.
Concept 4
Core 1 (220-1201) question cues
Classification: Given a brief scenario, select PAN/LAN/WLAN/WAN; Distinction: Explain why a remote intersite link is WAN rather than LAN; Context clue questions using physical medium or geographic scope.
Example
Two branch offices connected via leased line or carrier service -> WAN.
