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.
