Quick Reference - LAN vs WAN

LAN - Local Area Network:

  • Coverage: Small area (single building/campus)
  • Owner: Private (one organization)
  • Speed: Very fast (1-10 Gbps)
  • Cost: Low (one-time hardware)
  • Infrastructure: Ethernet, WiFi, switches (owned)
  • Example: School network, home WiFi

WAN - Wide Area Network:

  • Coverage: Large area (cities/countries/global)
  • Owner: Third-party telecoms providers
  • Speed: Slower (10-1000 Mbps)
  • Cost: High (monthly rental fees)
  • Infrastructure: Fiber, satellite, phone lines (rented)
  • Example: The Internet, corporate WAN

The Golden Rule:

LAN = Small, fast, privately owned. WAN = Large, slower, third-party infrastructure. Always mention BOTH size AND ownership!
