Computer Science

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?

These are the things that I wish to address..what are the similarities between Advertising and Literature?

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.

The OFFICIAL discussion I want you to engage in this week is answering this question: Compared to the person-to-person surveys we did for study one, what are the benefits of using qualtrics and the costs of using qualtrics to do research. Which do you prefer and why? Why is it a good / bad idea to use this online system to collect data? I attached the qualtrics survey

1.  Last week you read the Systems Planning course module that defined a Systems Development Life Cycle with 5 phases.  Explain the role of the systems analyst during each phase of the SDLC.  What types of questions should the systems analyst ask in each phase?  2.  Explain why the systems analyst role can be considered either a “business” role or an IT role.  Then, explain which category you would put it in.  Do you think you would like to be a systems analyst? Why or why not?

Assignment Content Every developer is focused on transmitting data securely. Hashing and hash functions are essential for securing business information and data. While the term cryptographic hash function may sound intimidating, it’s much simpler than it sounds. For this assignment, expand on the information provided in the course and fully address the items below. Write a 2- to 3-page paper in which you: Define cryptographic hash function (CHF). Elaborate on the main properties and definitions of an ideal cryptographic hash function. Propose 2 business applications or uses for a cryptographic hash function (e.g., password verification) and include a description of how it is used. Format your paper according to APA guidelines.

1.       A local area network (LAN) is a communications network that interconnects a variety of data communications devices within a small geographic area and broadcasts data at high data transfer rates. Expand on this definition by explaining the various terminology used such as “data communications devices”, “within a small geographic area”, “high data transfer rates”.   2.       How does a star-wired bus topology work?   3.       If a network were described as 100BaseT, list everything you would know about that network.   4.       Explain the switch filtering function.   5.       What are the functions performed by a network operating system (Describe at least five)?   6.       What are some of the features offered by Windows server 2019 (Describe at least five)?   7.       What are some of the more common RAID techniques (Describe at least five)?   8.       Briefly explain the evolution of the wireless LAN protocols.
