A computer network is a grouping of computing hardware and software devices linked together to facilitate communication and resource sharing among a wide range of users

Unit 2: Networking (L4)

Objective This coursework is designed in the form of set questions and design scenario. The tasks are divided into four sections, with section compromising several questions. The coursework should be submitted as one document in a report format.

LO1 Examine networking principles and their protocols

A computer network is a grouping of computing hardware and software devices linked together to facilitate communication and resource sharing among a wide range of users. Discuss the benefits and constraints of different network types and standards. There are several different types of network topologies, each with advantages and disadvantages. Explain the impact of network topology, communication and bandwidth requirements. To operate efficiently, the infrastructure of a network consists of devices that conform to well-known standards and protocols. Compare common networking principles and how protocols enable the effectiveness of networked systems. Considering a given scenario, identify the topology protocol selected for the efficient utilisation of a networking system.

LO2. Explain networking devices and operations

Considering the uses of switches, routers and other networking devices in the above scenario, discuss the operating principles of networking devices and server types used. At the same time, discuss the interdependence of terminal hardware in conjunction with relevant software in relation to application availability, Cost of ownership and other critical factors that can impact the network performance. Also, explore a range of server types and justify the selection of a server, considering the given scenario regarding cost and performance optimisation.

LO3. Design efficient networked systems

For a small business organisation, growth and success is considered as a major elements. There are several things that can enable in achieving efficient computer network. This has many benefits such as reducing unnecessary costs, raising your business outcome and increasing business efficiency. Design the network system based on the scenario given above. Also Test and evaluate the design to meet the requirements and analyse user feedback. Install and configure network services and applications of your choice. Design a maintenance schedule to support the networked system.

LO4. Implement and diagnose networked systems

Documentation is essential in troubleshooting networks in an effective and efficient manner. Troubleshooting will save the organisation time and money on the other hand .Therefore, before a technician can troubleshoot a network, proper documentation should exist, which will assist in finding the problem expeditiously. Implement a networked system based on a prepared design. Document and analyse test results against expected results. Recommend potential enhancements for the designed network systems. And finally, use critical reflection to evaluate own work and justify valid conclusions.
