Assessment: Due date: 05-May-2017TaskQuestion 1: Discuss the advantages and disadvantages of star, bus, and mesh physical topologies. Provide real examples of each type. (5 marks)Question 2:Explain encapsulation and decapsulation in a five layer TCP/IP protocolsuite. How does multiplexing and de-multiplexing differ fromencapsulation and decapsulation? (5 Marks)Question 3: Calculate the approximate bit rate and signal level(s) for a 6.8 MHz bandwidth system with a signal to noise ratio of 132. (5 Marks)Question 4:Explain why the OSI model is better than the TCP/IP model. Why hasn tit taken over from the TCP/IP model? Discuss the advantages anddisadvantages of both models. (5 Marks)Question 5: What is the total delay (latency) for a frame of size 5 million bits that is being sent on a link with 10 routers each having a queuing time of 3.5 s and a processing time of 1.8 s. The length of the link is 1900 km, the speed of light inside the link is 2.2 x 108 m/s, the link has a bandwidth of 8 Mbps. Which component(s) of the total delay is/are dominant? Which one(s) is/are negligible? (5 Marks)Question 6:According to RFC1939, a POP3 session is one of the following states:closed, authorization, transaction or update. Draw a diagram and explainto show these four states and how POP3 moves between them. (5 Marks)RationaleThisassessment consists of six questions assessing a basic understanding ofnetwork & data communication models, next generation IP andapplication layer paradigm. This assessment covers the followinglearning objectives: define and explain various Internet technologies;describe and analyse the role and importance of Internet technologies inthe modern world; and explain how different application layer servicessuch as client-server and peer-to-peer paradigms work in the Internet.Marking criteriaThefollowing guide will be used while assessing each component of thisassessment item. NB All your work must be cited (CSU APA), otherwise upto 100% of marks can be deducted.HDDICRPSFLIn depth synthesis of various Internet technologiesIndepth use of a good range of relevant literature to address thequestions. Clearly defines various internet technologies, with evidenceof synthesis of own research and prescribed reading in topics.Evidenceof using relevant literature to address the questions. Correctlydefines various internet technologies with evidence of synthesising someexternal readings and prescribed reading in topics.Useof some relevant literature to address the questions. Provides adefinition of various internet technologies. Mostly cited the prescribedtext. Synthesised concepts learned from topic readings.Limitedevidence of using relevant literature to address questions. Provides adefinition of various internet technologies but little evidence oflinkages or connections to topic readings.No clear definition or explanation when addressing questions. Little or no clear information provided.Evidence of applying own reseach to concepts of the role and importance of Internet technologies in the modern worldIndepth use of relevant literature to address the questions. Demonstratesa high level of information analysis of the role and importance ofinternet technologies in the modern world.Evidenceof using relevant literature to address the questions. Demonstrate agood level of information analysis of the role and importance ofinternet technologies in the modern world.Useof some relevant literature to address the questions. Demonstratesanalysis of information around the role and importance of internettechnologies in the modern world.Limitedevidence of using relevant literature to address questions. Provides adescription and some information around the importance of internettechnologies in the modern world without much analysis.No clear description or analysis provided to address the questions.Explain different application layer servicesNoerrors in the material presented, with an in-depth, clear,well-structured explanation of different application layer services.No errors in the material presented, with clear, well-structured explanation of different application layer services.Thematerial presented was generally clear and well-structured explanationof different application layer services with some omissions.Thematerial was generally presented in a clear manner, however some errorsor omission of information impedes understanding of what student istrying to explain in terms of different application layer services.Evidence that the student is unaware of the different application layer services.PresentationYourassessment should be submitted in either MS Word or PDF format (PDFusually preserves the formatting, MS Word may not). Please do not submityour assignment in any other format and also do not submit multiplecopies of the assessment. Please use A4 page size with Times New Roman /Ariel / Calibri font and use font size 11 or 12. The following shouldbe included as minimum requirements for the assessment.Imortant Note: All Questions must be more than 150 words. It should not have similarity more than 10% on Turnitin. Pictures should be with proper references and explanations. Document must be in APA format.Text Book and Reference Book:You must use the CSU APA referencing style for all cited material you have used inyourwork. You must use primary sources (ie Wikipedia is not acceptable,something you thought up yourself, because you think you know better, isalso unacceptable unless it has been published and peer reviewed -but it still needs to be cited).
