  39. 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. © 2007 Cisco Systems, Inc.
