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. Ethernet Technology and Internetworking Operating System In this assignment, you will study the advances in Ethernet technology, and learn about the role of routers in a network. Using the South University Online Library or the Internet, research the following: Advances in Ethernet technology Internetworking Operating System (iOS) and routers Based on your research and understanding, answer the following discussion questions: Question 1 Ethernet has proven to be a viable networking technology. It will continue to be a key player in networking in years to come. Why is it so? What are the latest advances in Ethernet? What is meant by an Ethernet switch? How does Ethernet also play a role in wireless technologies? Question 2 Routers are computing devices which need their own operating system (OS) to function. Some vendors refer to this OS as the iOS. What are the key roles of the iOS? On the other hand, routers must have interfaces. Why must each interface belong to a different network? Why are some routers more expensive than others?

Evaluate various IT Architecture models and based on your evaluation and testing highlight the best practices that can be utilized to improve IT management processes.

Research: How has technology helped people with physical challenges? Watch the Ted talk “How Technology Allowed Me to Read.” http://www.ted.com/talks/ron_mccallum_how_technology_allowed_me_to_read#t-64461 Write a brief commentary on the Ted talk In addition, research at least 2 additional assistive technology devices that are being used to help people with physical challenges. Write a summary of these technologies that have evolved to help the physically challenged. In your report, include your thoughts on how these technologies may impact the future.  The document must be a properly formatted MLA document. Document must include, minimum of 3, citations and a Works Cited. Upload the document to Moodle

Use articles from credible sources and summarise articles well and give your take on in-home Wi-fi and the privacy issues that come with it. Also, give info regarding how these issues are tackled.

Instructions In this unit, you have learned about management information systems (MIS) and the importance of it. For this assignment, compose a paper that discusses the key differences between data, information, information technology (IT), and information systems (IS). Your paper should address the components listed below. Define what is meant by information. Define what is meant by data. Create two matrices (one for data and one for information) that illustrate the key differences between information and data, place the matrices into your paper, and briefly discuss the differences in one or two paragraphs. Each matrix should contain characteristics and/or facts  about the subjects (data and information) that show how they are different. Define IT. Define IS. Using the five-component model as an example, discuss some differences between IT and IS. If you are using Microsoft Word, you can develop a matrix using this program. For an example of how to create a matrix using Microsoft Word, see the Microsoft.com explanation by clicking the link below. Microsoft. (n.d.). Create a matrix. Retrieved from https://support.office.com/en-us/article/Create-a-matrix-0E74423D-2E28-4DEB-9223-A30C2312CC22 You may use another computer software program that you are familiar with to create the matrices. However, you must submit your assignment in a Microsoft Word document, and the matrices should be included in the body of your paper. Your paper must be a minimum of two pages in length (not counting the title and reference pages), and you must use at least two resources as references. Any information from these resources must be cited and referenced in APA format.

Forensic software proposal Imagine that the cybercrime forensics lab where you work just received approval to purchase a new software suite to aid investigations. Your supervisor asks you to create a proposal comparing three leading computer forensic software utilities and to recommend which one you would purchase based on your research. Research three leading computer forensic software utilities that feature an entire suite of tools using the Internet. Consider the following categories while researching the forensic software utilities: Cost per license purchased Operating systems the suite can analyze, such as Microsoft® Windows®, UNIX®, and Linux® Number of included separate features, such as disk imaging, disk cloning, MD5 hash algorithm, or SHA hash algorithms Availability of password-cracking utilities Availability of drive-wiping utilities Ability of the software to use a Known File Filter (KFF), such as Innocent Images Write a 1,050- to 1,400-word proposal comparing the three software utilities you found and which utility you recommend purchasing. Include the following in your proposal: Compare the three software utilities. Describe how digital evidence is extracted using the software utilities. Explain how these software utilities can be used to apply forensic science to computers. Explain which of the three software utilities you recommend purchasing. Describe why you recommend this software utility.
