Computer Networks

This unit provides a foundation in the principles of data communications, network transmission technologies, and network protocols. It familiarises students with the basic design considerations and communication challenges involved in local area networks (LANs), wide area networks (WANs), and the Internet. Throughout the course, students will develop practical skills in identifying and troubleshooting data communication, switching and routing issues across all layers of a network.




Content includes: fundamental concepts of data communications and networking; industry standards; communication media; data communication principles and protocols; network architectures; standard interfaces and transmission techniques; data integrity and security; LAN technologies; data link control; IP addressing and subnetting; routing protocols such as RIP; switching technologies and virtual LANs (VLANs); and the design and implementation of networks using industry-standard equipment, including Cisco routers and switches.

Learning Outcomes

On successful completion of this unit, students will be able to:

1. Apply a range of technologies to address data communication and networking challenges;
2. Demonstrate an understanding of data communication and network protocols, as well as network and information security threats and countermeasures;
3. Design subnetted networks that meet specific business requirements;
4. Implement and troubleshoot networks using industry standard technologies like CISCO routers and switches, and;
5. Participate in an academic community through reflective and critical engagement in academic texts and understanding of principles of academic integrity.
