2. Distinguish between different LAN technologies and environments, including the characteristics of the equipment and protocols used to provide connectivity and services in a shared environment.
3. Be able to construct a simple Computer Communications Protocol to provide error free links catering for latency and error detection and correction.
4. Have an appreciation of the Internet, its core protocols and the services provided.
5. Explain the role of switching, forwarding and routing in the Internet.
6. Describe and justify the Client-server model for software applications
7. Develop simple communications applications using the Socket interface.
