ENGR2881 Computer Networks

This topic introduces the fundamentals, standards, protocols and techniques for designing, building and managing computer networks. The topic will present the OSI model, data transmission protocols, circuit, packet and switching fundamentals, network topologies, network and data security, network design, optimisation, performance monitoring and measurement and an overview of the issues involved in the design and implementation of such systems. The topic will present the general principles of networked systems with contemporary examples such as web based multimedia content, portable and distributed computing, and how networked communications and devices are informing business practice.

This topic aims to:

• Introduce students to the fundamentals of the networked systems they use
• Illustrate the relationship between operating systems and network management
• Demonstrate the fundamentals of network security requirements
• Provide students with a working knowledge of network configuration and management
• Provide students with a good understanding of how networked systems work to facilitate the functionality of computing technologies
• Provide students with an opportunity to demonstrate an ability to design and implement network control and monitoring programs

1. Understand computer network terminology and topologies, functions and architectures of computer networks
2. Demonstrate the design and implementation of simple process and network level programs
3. Demonstrate an understanding of the various layers which make up networks and how they are used to form complex, reliable and secure communication mediums
4. Understand and be able to articulate the structure and function of the major types of networks in common use
5. Understand aspects of the internet, including various associated protocols IP, UDP, TCP, IP addressing, header fields and the operation of servers / clients
6. Appreciate the real-time nature of networked devices and communications and demonstrate an understanding of current and emerging methods for secure information transfer
