Describe two differences between a Local Area Network (LAN) and a Wide Area Network (WAN).

• LAN is typically within a single building, while WAN spans multiple locations; LAN has higher data transfer speeds than WAN.

• LAN uses wireless technology only, while WAN uses wired technology only.

• WAN is typically within a single building, while LAN spans multiple locations.

• LAN has lower data transfer speeds than WAN; WAN is used for public internet access, while LAN is not.
