Content Analysis ePortfolio Assignment ITECH1102 Networking and Security Content Analysis ePortfolio Assignment Overview This assignment has three major aims: · To help students gain a good understanding of all ITECH1102 theoretical and practical material. · To encourage students to use content analysis summaries to prepare for tests, examinations and to help their understanding of theoretical concepts. · To encourage students to conduct an independent investigation into networking related topics from books, the Internet and through practical investigation. Engagement with this assignment should help students to prepare for the laboratory test (10%) in week 7, the theory test (0%) in week 8 and the end of semester examination (60%). Timelines and Expectations Students are required to analyse the weekly lecture material of topics 1 to 8, based on the classification given in (a) and create concise content analysis summaries of the theoretical concepts contained in the course lecture slides. The content analysis for each topic should not exceed approximately four (4) A4 sides of the paper if those topics content were printed. In addition, students need to complete the selected questions from the problem sheet associated with each week from 1 to 8, based on the classification given in (b). The selected questions from the problem sheet are given in Appendix A. (a) Each student is required to submit the content from three topics. The specific topics depend on your surname: Surnames starting with A - G Topics 4, 6 & 8 Surnames starting with H - Z Topics 3, 5 & 7 (b) Each student is required to submit the solution to the questions (see Appendix A) from the problem sheet from three topics. The specific topics depend on your surname: Surnames starting with A - G Topics 3, 5 & 7 Surnames starting with H - Z Topics 4, 6 & 8 Where the lab content or information contained in technical articles from the Internet or books helps to fully describe the lecture slide content, discussion of such theoretical articles or discussion of the lab material should be included in the content analysis ePortfolio. Suggestions as to possible inclusions in your content analysis ePortfolio will appear in weekly Work Plan documents on Moodle. The ultimate aim of this assessment task is to help ITECH1102 students to fully comprehend the course material and hence help them to pass tests and the examination. Mahara ePortfolio Students are required to create their content analysis and problem sheet documentation as an ePortfolio in Mahara. Each week’s topic should be on a separate ePortfolio page in order to separate the content into logical sections. For Instance, if your surname starts with B, then your ePortfolio pages will be as follows: 1. ePortfolio problem sheet page for Topic 3 2. ePortfolio content analysis page for Topic 4 3. ePortfolio problem sheet page for Topic 5 4. ePortfolio content analysis page for Topic 6 5. ePortfolio problem sheet page for Topic 7 6. ePortfolio content analysis page for Topic 8 By the end of week 10 (due date) all students should submit their content analysis and problem sheet ePortfolio pages through Moodle for marking. All the steps required to create and submit the ePortfolio pages can be found at the following link: http://studyskills.federation.edu.au/technology/university-systems/mahara/ More guidelines on the use of Mahara ePortfolios is available in the Resources section of the ITECH1102 Moodle site. Learning Outcomes Assessed The following course learning outcomes are assessed by completing this assessment: · K1. Describe and explain the role and function of network connectivity in current computing. · K2. Describe and explain the principles of communication in networks. · K3. Describe the role and functionality of hardware and software entities that contribute to the network communications. · K4. Describe and explain the protocols and interactions that implement network communications. · K6. Describe fundamental aspects of cloud computing. · A1. Apply networking architecture knowledge to analyze the networking needs of business. Assessment Details All work submitted must be authored by the student submitting the work or where material from other sources is included it must be referenced using APA referencing. Students found to have plagiarised will be dealt with according to university regulations. Submission Students are required to submit their ePortfolio to Moodle by 5:00 pm on Friday 18th May 2018. Marking Guidelines Content precisely presented based on references for Content Analysis topics. 25 Marks Presentation (Layout, no grammatical errors and reads well etc.) for Content Analysis topics. 10 Marks Cited References in Content Analysis topics. 5 Marks Total marks for each Content Analysis ePortfolio Page 40 Marks Total marks for each Problem sheet ePortfolio Page with correction solution for each question. (Please note: All questions in Appendix A carries equal marks) 10 Marks In this assignment, each student will have to do three content analysis pages and three problem sheet pages. Based on this, the total marks for this assignment is 150 (= 40 x 3 + 10 x 3) and 15% Weighting for the course. The marks will be available in Moodle and in FDLMarks by the end of week 12 of the semester. Appendix A The following table list out the questions to be answered, in each problem sheet, for the topics from 3 to 8 Topic 3 Topic 4 Topic 5 Topic 6 Topic 7 Topic 8 Question 4 Question 5 Question 10 Question 5 Question 3 Question 5 Question 7 Question 7 Question 12 Question 8 Question 4 Question 8 Question 8 Question 19 Question 14 Question 14 Question 5 Question 9 Question 10 Question 20 Question 18 Question 15 Question 6 Question 10 CRICOS Provider No. 00103D Content Analysis ePortfolio Assignment.docx Page 1 of 3 CRICOS Provider No. 00103D Content Analysis ePortfolio Assignment.docx Page 2 of 3 Faculty of Science & Technology Networking and Security problems (Topic 3) Topic 3 Problems Describe the origins of the term Sneaker Net. Complete the following sentences with regard to networking roles: A Client is a …………………… of network services. A Server is a …………………… of network services. Describe the difference between Clients and Peers as the terms relate to networking. Describe why Peer to Peer networks are less than ideal for campus sized networks. Define the terms: IaaS SaaS Describe the differences between these three different cloud services mentioned in the lecture slides. You have just created an Application Layer client program that uses a new protocol (named ITECH1102) you have developed. Assuming it is a TCP/IP application show the structure of a Data Link frame. What is held in the first 12 bytes of the frame mentioned in the last question? Describe how the ping program works. Using LinuxLite and Wireshark, determine the size of all parts of a ping request frame. (Do this by capturing a ping packet that you generate from your Linux Lite machine).
