The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered. For this assignment, make sure you post your initial response to the Discussion Area by the due date assigned. To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format. Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Complete your participation for this assignment by the end of the week. The OSI Model In this assignment, you will study the network architecture and learn how information moves between the layers of the OSI model. Using the South University Online Library or the Internet, research the following: Network architecture The OSI model Based on your research and understanding, respond to the following: What is a telecommunications network protocol? What is telecommunications network architecture? Select a network protocol and provide details on the steps that preceded the formal adoption of the protocol by the industry. Make sure you provide dates and organizations which were involved in the process. How are analog signals converted to digital signals for transmission over a telecommunications network? What are the advantages and disadvantages of digital over analog? What is the role of digital modulation in transmitting digital signals from source to destination? Make sure you use diagrams to support your discussion. In the OSI model, three layers divide the application layer from the network layer: presentation, session, and transport. The application layer is closest to the end user and the network layer is closest to the physical network. Based on the functions of the three layers between application and network, how do you anticipate the implementation of these layers changes from application to network, as information is moved from one layer to another? What is the importance of understanding the functions of these layers? How are layers represented in the TCP/IP model?

For this assignment you will be watching a video lesson, coding time during the lesson, and writing a reflection on the lesson. Please note, you MUST code this lesson independently. The likelihood of two people who have just learned to code getting the same exact results is minimal. The questions that will guide your reflection are: What went well/did not go well in your lesson? Use specific examples of things that occurred during the lesson? Explain how you actively engaged students in learning tasks aligned with the objectives in the psychomotor domain. Using examples from the lesson, explain, use the coding data, how you maximized students’ engagement in the lesson. If you could have done better, explain how, using the data. What did you learn about your job of coding? How did the teacher do based on that job and your observation of the lesson.

Provide an overview of the capabilities of a software testing tool. The tools listed below are simply examples of some of the many tools in this area. Your summary should be 2-4 pages long, double-spaced, 12-point font.  Discuss whether the tool you chose would be appropriate for small projects, e.g., an agile project, or a large project, involving potentially hundreds of developers.  List the features of the tool. Does it support “statement coverage, decision coverage, condition coverage, MC/DC, mutation testing”, … A table listing the testing criteria that we have talked about in class with a checkmark for the ones covered by the tool would be a good way to present this information.  Possible testing tools: JUnit, CppUnit (or other XUnit), FIT, FitNesse, qTest, Zephyr, etc. Remember to appropriately cite any publications you use in writing your overview.
