39
© 2006 Cisco Systems, Inc. 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.
