Aims

Computer networks have become an essential tool enabling users to obtain information and to co-operate on applications. This course unit aims to give an understanding of the principles of data communication and computer networks. It will cover the principle of network protocols, structures, standard and services mainly concentrating on wired networks but with a mention of wireless in places.

Learning Outcomes

On successful completion of this course unit you will:

Understand the characteristics and applications of various networking technologies. (A)
Understand how a collection of communication protocols co-operate and communicate to achieve the overall communication function. (A)
Have a working knowledge of at least one protocol at each of the main levels of the OSI seven layer reference model. (A)
Carry out network designs using appropriate hardware and software components to provide specified services for a given site. (B)
Be able to calculate message delays and throughput for a given application. (B)
Be able to specify the implementation of a simple protocol. (C)
Understand packet forwarding and the role of routing protocols. (A)
Understand error detection and recovery mechanisms. (A)
Understand how features such as flow control and quality of service are achieved. (A)
For given scenarios, demonstrate an understanding of 6, 7 and 8. (B)
Appreciate how internetworking demands changes in the operation of basic techniques. (A)
Be able to design and implement a program that allows client-server file transfer. (C)

Assessment of Learning outcomes

Learning outcomes 1, 2, 3, 4, 5, 7, 8, 9, 10 and 11 are assessed by examination Learning outcomes 6 and 12 are assessed in the laboratory.
