3.0.3 Class Activity – Design a Communications System (Answers)

 3.0.3 Group Project - Create a Communication System (Instructor Version)

Instructor Note: Text in red font or with grey highlights appears solely in the instructor copy.

Objectives

Describe the function of protocols and standards bodies in supporting network communication interoperability.

Context / Scenario

You've just acquired a new car for personal usage. After about a week of driving, you notice that the automobile is not operating properly. You decide to take it to an automobile repair business that many of your friends strongly suggest after discussing the issue with them. It is the only repair facility in the immediate vicinity.

When you arrive at the repair shop, you discover that the mechanics all speak a foreign language. You're having difficulties explaining the vehicle's performance issues, but the repairs are very necessary. You're not certain you can drive it back home to do more investigation.

You must devise a strategy for collaborating with the repair facility in order to guarantee that your car is repaired appropriately.

What method of communication will you use to communicate with the mechanics? Create a communication model to guarantee that the vehicle is fixed appropriately.

Note to the Instructor: This Modeling Activity is not a graded assignment. Its objective is to get students thinking about how a communications system allows the movement of data from source to destination (personally and incorporate practice). As a consequence of this action, a discussion should be begun.

Question of Reflection

Which actions did you deem necessary for effectively expressing your repair request? Justify your response.

To remedy this problem, the following measures may be taken:

Establishing a communication language (which might be spoken, written, or kinesthetic/physical). Explain the situation with the vehicle very carefully (in tiny stages) (again, using speech, written/pictorial representations, or kinesthetic/physical representations).

Inquiring about the mechanic's knowledge of the situation.

Awaiting the completion of the repair.

Driving the vehicle to confirm that repairs were completed successfully.

The meeting is concluded by paying for the repairs and expressing gratitude to the technician.

Identify model components that correspond to IT content:

Developing a language for communication (Application protocol)

Dividing the communication into manageable chunks to enhance comprehension of the issue to be handled incrementally (Transfer protocol).

Checking to ensure that the message was sent and understood accurately by the technician who will do the repairs. (Protocol Internet)

Automobile delivery and wait time for repairs (Network Access protocol)
