 Internet Fundamental

Description:

The aim of this subject is to provide an overview of the Internet at a system level. In other words, the subject will provide an operational description of the Internet and its main components. The following topics will be covered: Internet evolution and current status, generic network infrastructure and configuration, layered communication architectures and protocols, access technologies, Internet security and management, case studies of Internet applications.

Students who successfully complete this subject will acquire the following competencies and abilities. In particular, students will be able to: 1. explain the Internet system functionality including the interrelationships between various components, 2. describe typical Internet networking solutions including access technologies, 3. explain peer to peer layered protocol architectures, 4. describe and understand the various issues and trade-offs associated with Internet security and management aspects; and 5. demonstrate appropriate practical skills in terms of typical Internet applications and their requirements. 

 Internet Technology

Description:

This subject introduces students to the fundamentals of computer communications. These fundamentals are then used to outline the Internet Architecture, and describe its key components. Following this, the operation of the World Wide Web (WWW) will be detailed. Topics covered include packet switching, switched networks, layered protocols, Local and Wide Area networks, WWW operation, network components (e.g., routers), access technologies (e.g., modems). Laboratory exercises will illustrate key computer communications concepts.

After successfully completing this subject, the student should be able to: 1. describe packet switching and switched network architectures; 2. identify key Internet components; 3. demonstrate an understanding of how internet component behaviours determine overall Internet performance; 4. explain how access devices, e.g., modems, transfer information; 4. demonstrate an understanding of the protocols, eg., http, which underpin the operation of the WWW; and 5. write reports on exercises undertaken.  

 Telecommunications Network

Description:

Space division switching. Single stage and multi-stage division switches. Efficiency and reliability considerations. Time division switching techniques. Routing. System considerations and routing strategies. Network topology and modelling. Applications of queuing theory in the study of telecommunication networks. Simulation techniques. Advanced telecommunication networks (ATM, B-ISDN, etc.).  

 Instrumentation & Measurements

Description:

The measurement of physical parameters, their translation to electrical quantities, transmission, recording, and analysis. Virtual instruments, process system modelling, output and translation to physical parameters. Emphasis is on design and synthesis using knowledge learnt during the course, applied to the solving of real world engineering problems. Specific topics to include transducers, data logging/acquisition, telemetry, industrial process controllers, automated laboratory instrumentation (including IEEE-488).
