3.4.1.3 Class Activity – Guaranteed to Work! (Instructor Version – Optional Class Activity)
Instructor Note: Red font color or gray highlights indicate text that appears in the instructor copy only. Optional activities are designed to enhance understanding and/or to provide additional practice.
Objectives
Explain the role of protocols and standards organizations in facilitating interoperability in network communications.
Background / Scenario
You have just completed the Chapter 3 content regarding network protocols and standards.
Assuming you resolved the beginning of this chapter’s modeling activity, how would you compare the following steps taken to design a communications system to the networking models used for communications?
| Steps to Communicate | Possible Answers | Associated TCP/IP Model Layer |
|---|---|---|
| Establishing a language to communicate | ||
| Dividing the message into small steps, delivered a little at a time, to facilitate understanding of the problem | ||
| Checking to see if the message has been delivered correctly to the mechanic who will be performing the repairs | ||
| Delivery of automobile and wait time for repairs |
Instructor Note: This optional Modeling Activity may be used as a graded assignment. It should demonstrate how network protocols and standards facilitate the transfer of data from source to destination, in both personal and in corporate practice. Facilitation of the discussion should include student-to-student discussions to show how students’ perceptions have been changed.
Required Resources
Blank “Steps to Communicate” table (above) for students to record their answers based upon their Chapter 3 content knowledge.
Reflection
How does your network model in developing an automotive repair communications plan compare to a network communications interoperability plan?
Students’ tables might look like this (with variations)
| Steps to Communicate | Possible Answers | Associated TCP/IP Model Layer |
|---|---|---|
| Establishing a language to communicate | Voice/Language (English,Spanish, French, etc.) Written pictures Kinesthetic/physical | Application Layer (HTTP, VoIP, POP, etc.) |
| Dividing the message into small steps, delivered a little at a time, to facilitate understanding of the problem | Small descriptions shared a little at a time | Transport Layer (Segments) |
| Checking to see if the message has been delivered correctly to the mechanic who will be performing the repairs_ | Asking the mechanic to repeat the full problem which is occurring with the automobile. | Internet Layer (Packets) |
| Delivery of automobile and wait time for repairs | Physical delivery of the automobile left for repairs – agreement upon the delivery/wait time for repairs | Network Access Layer (Bits) |
Identify elements of the model that map to IT-related content:
- Establishing a language to communicate (Application protocol)
- Dividing the message into small steps, delivered a little at a time, to facilitate understanding of the problem to be solved (Transport protocol).
- Checking to see if the message has been delivered correctly to the mechanic who will be performing the repairs. (Internet protocol)
- Delivery of automobile and wait time for repairs (Network Access protocol)
