Unit description Unit description

This unit introduces basic data communication concepts, theory and practice within the context of the use of communication networks in organisations.

Topics include:

  • protocols and standards, including the OSI model
  • in-depth understanding of key protocols of the TCP/IP protocol suite
  • network switching and routing, including both intra-domain and inter-domain routing protocols
  • LAN and WAN topologies
  • wireless networking
  • network hardware, such as routers, modems, repeaters, switches and hubs
  • public telecommunication-based data services
  • the effect of telecommunications on society
  • the role of telecommunications within organisations
  • introduction to security and network management
  • organisational management of telecommunications
  • introduction to network design
  • regulatory frameworks

Practical work includes basic network configuration and protocol performance using specialised software.

This unit does not presume any knowledge of programming nor is there any programming work in the unit.

Learning Outcomes

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

  • ULO1: Explain the importance and the role of network protocols including why they are organised into protocol stacks and how protocol stacks function.
  • ULO2: Demonstrate an understanding of network addressing, routing of traffic between networks and the mechanisms that allow applications to co-exist and interact.
  • ULO4: Critically reflect on different major network technologies including wireless, backbone, wide area networks, and the Internet and, being aware of their properties, be able to evaluate different network designs.
  • ULO3: Differentiate among LAN components, describe addressing schemes at various layers and how they interact, techniques to resolve them, and in particular instances calculate addresses.
  • ULO5: Demonstrate technical networking proficiency including demonstrated ability to configure, construct, and document, and in simple cases, design networks, as well as the ability to perform traffic analysis on local area networks.
  • ULO6: Demonstrate an understanding of, and have an ability to develop plans for dealing with, issues regarding network security and management.
