- Local Area Networks (LAN's) link several computers in a building.
- The LAN can then itself be linked to other LAN's.
- The Internet is made up of thousands of LAN's.
- Provide the highest speed connections among
- Cannot span large distances
- Typical LAN spans small building and operates between
4 Mbps and 2 Gbps
- Usually bus based (Ethernet) networks.
Figure: Local Area Connect to Wide Area Networks
- Sometimes called long haul networks
- Allow endpoints arbitrarily far apart
- Intended for use over large distances
- Operate at speeds from 9.6 Kbps and 45 Mbps
