Overview

Create an OSI model for a generic work environment and write a report based on the model you created.

By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:

Competency 2: Explain fundamental standards of networking technology. Create a usable OSI model. Describe the importance of the work performed by the identified network protocols.

Competency 3: Explain the components of a network. Explain the network protocols used in the OSI model. Explain the purpose and role of at least three of the identified network protocols.

Competency 4: Apply collaboration strategies in the network design process. Apply the assessment's assigned lab concepts and activities.

Competency 6: Communicate effectively. Communicate in a manner that is scholarly, professional, and consistent with expectations for members of professional communities.

Context

The protocols that make up the TCP/IP stack can be compared with the OSI model. Comparison of these two conceptual models is helpful in understanding how the protocols work and the purpose they serve in moving data from one host to another. Because of the success of the standards-setting organizations, there are a number of protocols common to most networks. The most commonly used protocols are identified and the role that they play in transmitting data is detailed, as well as the OSI layer at which they function. Understanding the layer at which protocols function is helpful in selecting the protocols to be used to create the network.

To deepen your understanding, you are encouraged to consider the questions below and discuss them with a fellow learner, a work associate, an interested friend, or a member of the business community.

TCP/IP is a suite of protocols. Consider one protocol with which you are familiar. For what is the protocol used. Why is it important? What would occur if the protocol was not working or was unavailable?

The OSI model is a template that all protocols are compared against. What are layers of the OSI model? How do TCP/IP layers compare?

If you choose to qualify for an exam voucher, you must use the Preset Exam Experience option and achieve a qualifying score on the Random Exam. See the Industry Certifications page for qualifying criteria details.

Assessment Instructions

For this assessment, create and describe the information flow of an OSI model.

To begin, select a generic work environment, such as any office that would use a phone system, to use as an example to describe how this is done.

Also, complete the practice labs provided in the Virtual Resource Portal activity for this assessment. Use these labs and the Internet to gather the information necessary to create your own analogy essay of the flow of information through the OSI model. Your analogy will include network protocols and compare these against the OSI model.

Then, complete the following:

1. Create an OSI model for a generic work environment. You can use Microsoft Word to do this.

2. Write a report that addresses the following, based on the OSI model you created. Provide an explanation of at least three different network protocols used in the OSI model.

Explain the purpose and role of at least three of the network protocols you identify.

Describe the importance of the work performed by the network protocols you identify. This may include how well they do with network security. Examples include TCP/IP traffic and port security.

Apply the concepts from the practice lab activities for this assessment.
