 Aims To enable students to better understand, develop, design and improve analogue and digital communication systems, with an awareness of all the main factors involved, and evolution of technologies toward data communication network.
 Learning outcomes A. Identify and explain the nature of data and how it is stored and communicated. B. Interpret the limitations imposed on communication system performance and design by various factors.C. Explain how noise arises in communications systems and its effects upon communications system behavior and performance.D. Apply some of the methods to combat the adverse effects of noise in communications systems E. Explain why standard protocol architecture is needed in data communication and interpret the basic components in a communication network. F. Identify different topology and design basic routing algorithms applied in a data communication network.
 Method of teaching and learning This module will be delivered by a combination of formal lectures, tutorials and assignments.
