Description This subject is concerned with the principles and topics of fundamental importance to digital data communication, computer communication networks and telecommunications. The lower layers of the protocol structure (physical layer, data link layer and some aspects of the network layer) and the physical medium (hardware and transmission lines) are emphasized. An engineering approach will be taken to provide an insight to transmission and transmission media, communication techniques and transmission efficiency.

Learning Outcomes

On successful completion of this subject, students should be able to:
  1. Outline common data transmission concepts and techniques.
  2. Identify the concepts and physical mechanisms underlying data communication in telecommunication networks.
  3. Analyse the telephone network to identify the concepts and physical mechanisms underlying data communication.
  4. Evaluate the differences between circuit switching and packet switching, and explain how a data communication system can detect and correct channel errors in transmission.
