Networking is a fundamental part of today鈥檚 information technology landscape. Online communication, commerce and a myriad other services depend on robust underlying networks. Security is also a key component of every aspect of information technology and security in the network is often the first defence against security threats. Foundational knowledge and experience in computer networking is essential for IT professionals across a wide range of careers, especially in today鈥檚 world of mobile communication and distributed work. The course structure takes a top-down approach, starting at looking at network applications and then discovering the underlying principles and techniques.

The course provides students with an understanding of how wired and wireless networks function, and provides a working knowledge of network addressing, fundamental of wired and wireless networks. Starting with studying some common communications protocols critical to today's networked world, the course progressively introduces the underlying structure of the network that ultimately supports networked applications. Security is introduced, in the context of threats and techniques for their mitigation. This course will provide students with the knowledge and skills to design and implement a simple network.
