This document discusses ways to expand computer networks through the use of networking devices like repeaters, bridges, routers, and gateways. It describes how these devices can connect local area networks (LANs) together into wider area networks (WANs) by establishing links between LANs either physically through cables or remotely. The document also mentions techniques for intelligent routing of data packets between different network protocols and optimizing network performance.
