Contracting out Zero-slot LAN
Connecting computers with existing serial or parallel ports

Sub-LANs A different approach that provides a subset of
LAN capabilities – good for peripheral sharing and file transfers Has lower data transfer rates Lower costs Gets implemented with physical data switches However, hard to expand Contention problems
