Objectives

Explain the role of protocols and standards organizations in facilitating interoperability in network communications.

Background / Scenario

You have just purchased a new automobile for your personal use. After driving the car for a week or so, you find that it is not working correctly. Discussing the problem with several of your peers, you decide to take it to an automotive repair facility that they highly recommend. It is the only repair facility located in close proximity.

When you arrive at the repair facility, you find that all the mechanics speak another language. You are having difficulty explaining the automobile’s performance problems, but the repairs really need to be done. You are not sure you can drive it back home to research other options.

You must find a way to work with the repair facility to ensure your automobile is fixed correctly.

Asking the mechanic to confirm his/her understanding of the problem.

Waiting for the repair to be done.

Driving the automobile to ensure repairs were successful.
