COMP2221 Networks
Module summary
The internet and other computer networks are an inescapable part of modern day life. Network devices form the physical infrastructure and network protocols define the means of communications. As trends in Computer Science are tending towards massively parallel computer systems it becomes more important that Computer Science practitioners have a solid foundation in network architecture, network programming and network security.This module introduces the protocols, hardware and architectures used in computer networks and will provide students with the opportunity to develop network application.Objectives
This module provides the fundamental understanding of network programming, network architecture and security consideration of network applications.
Learning outcomes
On successful completion of this module a student will have demonstrated the ability to:
1. describe the key components of a computer network.
2. design, implement and test network protocols and applications.
3. evaluate network protocols in terms of efficiency and security.
4. select appropriate network protocols for specific applications.
Syllabus
This module covers the following 3 topic areas:
- Network programming : design patterns and network protocols (TCP, UDP, DNS, DHCP, SMTP and POP3).
- Network architecture : local area networks, metropolitan area networks, wide area networks, OSI model.
- Network infrastructure : Ethernet, 802.11a/b/g/n, network devices (switches, routers and access points).
