PowerPoint Presentation Instructions In this assignment, you will create a presentation for your organization to explain how successful collaboration can improve success and provide competitive advantages. Scenario: Your organization has used a variety of collaboration systems developed by some project managers. Some of these systems were successful while others were not. Your organization has one unique challenge—many of your employees are staffed at other locations or work from home (telework). You would like to standardize the collaboration process to improve team communication for all company projects. In your presentation, you should include the elements listed below. Explain why collaboration information systems (IS) are important from the organization’s perspective. Discuss how collaboration tools can improve team communication. Identify three tools that will be used for synchronous communications and three tools that will be used for asynchronous communications. Be sure to explain why you made these choices. Describe how project files, such as Microsoft (MS) Word, MS Excel, MS Project, and MS Visio, will be shared with team members. Be sure to explain the rationale behind your choice. Explain how the task list for managing tasks will be shared with team members. Be sure to explain the rationale behind your choice. Discuss how this new collaboration IS could provide competitive advantages for your organization. Your presentation should be a minimum of six slides in length (not counting the title and reference slides). Use of images, graphics, and diagrams is encouraged. You can use an industry of your choosing or examples from your personal or professional experiences in developing this assignment. You can also use the resources in the Unit II Suggested Reading section to assist you with this assignment. Be sure to follow the 7×7 rule (i.e., there should be no more than 7 words per line and no more than 7 lines per slide). You are required to use speaker notes to discuss the bullet points on your slides. You must use at least two academic resources to support your presentation, and you must cite (in APA format) any information on your slides or in your speaker notes that came from these sources.

Instructions: This is an individual assignment. Use the blackboard to submit your word file with answers by 11:59 pm on the due date (no hard copies please). Late submissions will receive a zero grade. Start working on this early.     1.  Business case: Analyze the following business case and provide your recommendations. Big E. Bank  Nancy Smith is the director of network infrastructure for Big E. Bank (BEB). BEB has just purchased Ohio Bank (OB), a small regional bank that has 30 branches spread over Ohio. OB has a WAN connecting five cities, in which it has branches, to OB’s main headquarters in Columbus. It has a series of MANs in those cities (MAN is a “Metropolitan Area Network”, which usually spans a city), which in turn connect to the LANs in each of the branches. The OB network is adequate but uses very different data link, network and transport protocols than those used by BEB’s network. Smith’s task is to connect OB’s network with BEB’s network. She has several alternatives. Alternative A is to leave the two networks separate but install a few devices in OB’s headquarters to translate between the set of protocols used in the BEB network and those in the OB network so that messages can flow between the two networks. Alternative B is to replace all the WAN, MAN, and LAN network components in OB’s entire network so that OB uses the same protocols as BEB and the two can freely communicate. Alternative C is to replace the devices in OB’s WAN (and possibly the MANs) so that each city (or each branch, if the MANs are replaced as well) can communicate with the BEB network but leave the LANs in individual branches unchanged. In this case, the device connecting the MAN (or the branch) will translate between the OB protocols and the BEB protocols. Your job is to develop a short list of pros and cons for each alternative and make a recommendation.       2. What are the network applications? Give two examples.       3. What is packet switching, and why is packet switching relevant to the Internet?   4. Give a brief explanation of the layers in the ISO Open system Interconnection model.             5. Describe types of interferences and how to mitigate them.             6. Describe multi-mode and single-mode fiber and their limitations.

Pick a topic that is relevant to managing information security, cyber security/cyber awareness and explain why you chose that topic and how it is important to today’s modern world. This is an analytical and prescriptive assignment: You must identify a problem, and address the problem or challenge’s causes, implications and possible solutions. Must also include a title and reference page as well.

The Network Research Project (NRP) expectations are to explain the concepts you are learning as part of this Networking Fundamentals course.  This is not an extensive review of the topic areas, but instead a cursory exploration of any approved topic you find most interesting. You should consider the additional details below to guide you through completion of the NRP. Quality is valued over quantity, but quantity is necessary for a quality project submission.  It is estimated that 4 – 6 pages (not including the title page) would be necessary to address each Network Research Project (NRP) topic. Each Network Research Project (NRP) must have an Introduction.  The introduction should address the purpose of your project, and an overview of what you will convey to the reader.  It should summarize your research project in such a way that readers can rapidly become acquainted with the material.  Each NRP must also have a Conclusion.  The conclusion should summarize your findings in a succinct manner.  The conclusion will regurgitate key points of the research project for the reader.  The remaining format will be at your discretion.  It is suggested that you review the NRP details under each approved topic below, and outline the project accordingly.  You should maintain a consistent format throughout the entirety of the document. You should use proper grammar, terminology, and expand acronyms in each paragraph they are used. For example, the first time in a paragraph an acronym is used it should be expanded (e.g., University of Maryland Global Campus (UMGC)).  Thereafter, and as long as you are in the same paragraph, the acronym (e.g., UMGC) can be used. When starting a new paragraph, the rule begins anew.  Student should leverage Grammar Essentials to aid in their research submission. All sources must be cited using the APA 7th Edition. You will need to use multiple sources of information within the NRP. TestOut LabSim may be one of those sources. UMGC offers a Citing and Writing Portal that you should take advantage of.  Do not plagiarize any material or content.  The use of figures and diagrams is encouraged where appropriate. Summarize cloud concepts and their purposes. Types of services (SaaS, PaaS, IaaS) Define and describe each type of service. Compare and contrast these cloud services are related? Cloud delivery models (Private, Public, and Hybrid) Compare and contrast the cloud delivery models. Connectivity methods Provide further details on cloud connectivity methods. Security implications / considerations Describe security implications and considerations for organizations moving to the cloud. Describe the relationships between local and cloud resources

Please only take this assignment if you know SQL a little bit and can write these answers. Guidelines for the writer:  I know all the concepts but I don’t have time to write them, but I will be checking with a lot of detail and asking for revisions as needed because it’s a very important assignment(30% of my grade).  No copying of any kind. Please don’t include too many references(maybe just 1-2 per question) as this assignment is supposed to be based on an understanding of concepts and writing in your own words.  I can give you access to lectures if needed. The ideal way to approach this would be, studying the concept a little bit, maybe watching youtube videos, and writing the answers on your own.  Message if you have any questions Please address each question with a target of 600 – 750 words each question. Please cite all material referenced (no cutting/pasting of any kind). Questions: 1. Explain what the instructor means by Organize or Die by providing specific examples on how the progression of human learning has impacted societies and organizations throughout human history. Why might this philosophy be introduced in a database design course? 2. Explain the structure, characteristics, philosophy, and impact of proper error-handling by providing specific examples on how and when RAISERROR and THROW are used. 3. Explain the purpose, structure, and impact of the various SQL commands known as control of flow’ language with specific examples. 4. Explain the purpose, structure and impact of a synthetic transaction while referencing a specific example. 5. Explain the purpose, structure, and impact of the systematic process for designing relational databases with attention paid to the process and characteristics of each development phase.
