37. Plan, Implement and Verify a Local Network • Connect and properly document the network installation

38. Plan, Implement and Verify a Local Network • Perform simple workgroup tasks in order to share resources

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.
