All rights reserved.Cisco PublicITE 1 Chapter 6 39 Summary  Information networks carry data using hosts as clients, servers, or both.  All computer communication involves a source, destination, and channel.  Rules called protocols govern computer communications.  Larger networks are divided into smaller, more manageable ones using a layered hierarchical design.  Each network host needs both a physical MAC address and a logical IP address.  Good network design requires a network plan.
