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!
