The field of networking involves a great number of different protocols used to transmit data between computer nodes. Each protocol has a specific purpose. Used properly, the protocols ensure that the data arrives at the intended destination as quickly as possible, and intact, and without being corrupted or intercepted. You should review common network protocols before the Cisco interview. Preparing for questions like these cuts down on the number of curveballs you may otherwise be unprepared to answer.

"Network Address Translation, or NAT, is a protocol that enables several computers on a single network to share one connection to the internet. NAT works to collect internet requests from individual nodes through a device such as a router and send them to the internet. NAT converts the private IP address from each node into a public IP address so that the internet will know where to respond with the user's information. NAT routes the information to the individual user through their private IP address."
