OverviewDescriptionComputer networks are now business critical in all modern organisations and business enterprises. They are important in everyday life. This subject introduces students to the fundamental issues in modern data communications and computer networks. This is essential knowledge for all users of IT, IT professionals and those who wish to specialise in computer networking. Students learn about the layered networking model and are introduced to networking devices and protocols. They learn how these are used in computer networks and in net-based application programs. The primary focus of this subject is Local Area Networks (LAN). Student practical work includes designing and building simple peer-to-peer networks and LANs that are connected to the Internet. The core set of protocols employed on the global Internet, TCP/IP, is studied.Subject objectivesUpon successful completion of this subject students should be able to:1. Explain the characteristics and functions of each layer of the OSI model in the network, and describe how data is moved across network, specifically, those relevant to the Internet Protocol.2. Describe and contrast the fundamentals of networking processes within and between networking hardware (packet forwarding with routers;frame forwarding of switches; media connections between routers, switches and PCs).3. Explain basic components of a Cisco router and a Cisco switch, and use Cisco IOS commands to complete configuration, management and troubleshooting tasks for: Basic router, switch and host TCP/IP configuration; & Enabling basic security on these devices.4. Apply VLSM Addressing to an Internet Protocol v4 (IPv4) Address given design criteria.5. Demonstrate proficiency in designing and implementing a hierarchical IPv4 and IPv6 addressing scheme.6. Recognise and make suitable choices for physical networking equipment and media, and build a small network.7. Demonstrate teamwork capability and communication skills.This subject also contributes specifically to the development of the following course intended learning outcomes:Identify, interpret and analyse stakeholder needs. (A.1)Establish priorities and goals (A.2)Apply systems thinking to understand complex system behaviour including interactions between components and with other systems (social, cultural, legislative, environmental, business etc.) (A.5)Identify and apply relevant problem solving methodologies (B.1)Design components, systems and/or processes to meet required specifications (B.2)Apply decision-making methodologies to evaluate solutions for efficiency, effectiveness and sustainability (B.4)Implement and test solutions (B.5)Demonstrate research skills (B.6)Evaluate model applicability, accuracy and limitations (C.3)Manage own time and processes effectively by prioritising competing demands to achieve personal goals (Manage self) (D.1)Identify and apply relevant project management methodologies (E.3)Teaching and learning strategiesNormal class contact time is comprised of 3 hours tutorial/laboratory session per week. In the laboratory a workshop approach is used which combines learning by doing small group and whole class discussion, web research, on-line activities, design activities, question and answer sessions, and on-line tests with immediate feedback. It is expected that students will need to spend an additional three hours in self-directed study for each lab session.As noted above, the workload for this subject will require students to exercise considerable diligence and to strive for efficient utilisation of class time and laboratory facilities. Accordingly, all computer activities which are not directly and expressly related to the curriculum are strictly prohibited in all networking labs. Any detected infringement will result in immediate expulsion from the laboratory.Content1: Exploring the Network· Networks and their Impact on our lives· Providing Network Resources ?
