3.4.1.3 Class Activity – Guaranteed to Work! Answers

Class Activity – Guaranteed to Work! (Answers Version – Optional Class Activity)

Answers Note: Red font color or gray highlights indicate text that appears in the Answers 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

Answers 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?

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)
