Communication Networks   In this part of the assignment, the student must demonstrate their understanding of common  communication networks with suitable diagrams by answering the following topics:  1. James is working from home using a microcomputer, a DSL modem, and a telephone  connection to the internet. His company is connected to the Internet and has both  local area networks and a mainframe computer. List and discuss the different network  connections in this operation.  2. Emma is sitting in the lobby of her hotel. She is accessing her email using her laptop  connected to the wireless network available in the hotel. Identify and discuss  communication in this scenario.  3. With her new cell phone, Isabella has just taken a snapshot of the Sydney Opera  House. Same time, she decides to send this amazing snapshot to the email account of  her friend Lisa across the country. Analyse the scenario and discuss the  communication networks involved.    B. Network Architectures   In this part of the assignment, the student must demonstrate their understanding of network  architectures answering the following topics:   1. Reflect on the feedback for Part A and discuss how did it help you to accomplish the  tasks for the assignment Part B.  2. Identify and discuss two reasons for using layered protocols. Report one possible  disadvantage of using layered protocols.  3. Differentiate the OSI reference model and the TCP/IP protocol suite with a suitable  diagram. Which layers are missing from the TCP/IP protocol suite? Are they really  missing? Justify your answer.  4. Explain, why is flow control required at both data link and transport layers?  5. Report one other network model which exists besides the OSI model and TCP/IP  protocol suite.   6. Analyse wired and wireless mediums with suitable examples in terms of cost, speed,  expandability & distance, environment, and security.  References   Must consider at least eight current references (three for part A and five for part B). Must  follow the IEEE referencing style.      Assignment Instructions:   Do not use Wikipedia as a source or a reference   Make sure you properly reference any diagrams/ graphics used in the assignment.

Deepti · Accepted Answer

Part A
1. The network setup possible with the given components is wired network connection. Wired network requires modem, phone and PC. Network adaptor will be installed inside the PC. The modem sends and receives information over the phone. It is required to connect to the Internet [3]. 
Alternate method of connecting to the network is through wireless network. Wireless Network adaptor will be installed inside the PC so that the wired connection between the microcomputer and the DSL modem is not required. The microcomputer should have built-in wirless capabilities to accomplish this connection. 
2. Emma is using Wi-Fi network connection of the hotel. This communication allows long distances within carefully controlled environments. The protocol shall work within the hotel premise. Emma avails Internet connectivity through wireless router of the hotel which allows her wi-fi-laptop to interface with the Internet and access her email [1]. 
3. Isabella is using Wireless Wide Area Network (WWAN) which transmits small packages of information between devices like the snapshot. It uses mobile telecommunication cellular network technologies like LTE, CDPD or GSM to transfer data. The network covers large geographical area as that in star or mesh network. 
Wireless Internet Access Points are also used or communicating wirelessly using smart phones and computers as in this case. Isabella’s phone has the necessary built-in wireless capability to communicate the snapshot to her friend. This may use hot spot or mobile wireless network. Hotspot uses free Internet access at some charge from ISP. Mobile wireless network provides high-speed Internet connection within the network’s range [5].
Part-2
2. The reasons for using layered protocols [7] are
· Abstraction: The implementation details remain secure through separation of implementation and specification. Abstraction can change implementation as long as service interface is maintained. The layering techniques hides information which in turn improves overall performance. Right amount of abstraction allows only the information sufficient for achieving good performance. It is the network layer that concatenates set of links to form abstraction of end-to-end link. Transport layer builds abstraction of multiplexed and flow-controlled end-to-end link. Thus, every layer provides abstraction to the layer above. 
· Specialization: The layered protocol technique breaks up the complex problem into smaller pieces. Layers compose simple service to provide complex services. Networking protocols are represented in a stack with layers which reinforces division of specialization.
