In LANs (Local Area Networks) and WANs (Wide Area Networks), routers and switches are the basic hardware components. Simple network switches have become ever more capable as technology and computing power has increased, so fundamental knowledge of the basic operations of switches is key to progress for the networking professional. WAN technologies provide connectivity across geographical areas, and are key to extending the reach of networks, and are also integral building block for the Internet as a whole. Though the industry certification is not formally part of this course, students undertaking this course will cover concepts and techniques which are consistent further progress towards the Cisco CCNA industry certification, should they wish to pursue it separately.

This course introduces virtual LANs as a tool to provide segmentation, flexibility and security of LANs. Link redundancy and aggregation are introduced to enhance the robustness of LANs. Network Address Translation is discussed as a method to conserve Internet Protocol Version 4 (ipv4) network address space. It also focuses on WAN technologies which span large geographic areas. After completion of this course, the students will be able to describe and select appropriate WAN technologies; handle switches; routers and wireless routers with confidence.

On successful completion of this course students will be able to:

1. Confidently design an operable LAN using network switches, and concepts such as VLANs, and layer 3 switching;
2. Implement a network incorporating switches and routers;
3. Analyse business requirements and choose appropriate WAN technologies;
4. Apply security measures to a network by programming switches and routers;
5. Describe the concepts of converged networks and the discuss the design issues and considerations;
6. Utilise techniques of network troubleshooting to identify problems in a network;
7. Relate how network documentation, network operations and network troubleshooting comprise critical components of a networking professional鈥檚 role;
8. Relate roles in network teams to the ACS Code of Ethics;
9. Recognise workflows and network team-based collaboration and how the network team interrelates with other areas of information technology, such as application development, IT management and others.
