Module Title:Computer Networks 2
Language of Instruction:English
Credits: 5
NFQ Level:7
Module Delivered In 4 programme(s)
Teaching & Learning Strategies: The module will be delivered using lectures, tutorials and laboratory sessions to illustrate the concepts under study. The Institutes VLE will be used to evaluate the students understanding of these concepts at the end of each section using multiple choice questions. Self test question sheets will be issued to the students at the end of each section.
Module Aim: To provide a study of Local Area Networks (LANs) and Wide Area Networks (WANs) in an IPv6 environment. This module provides opportunities for students to gain the skills and hands-on experience needed to design and test enterprise LANs and WANs using copper, fibre and wireless media.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Terminate, test and perform energy budget calculations for fibre optic communication links
LO2 Configure and secure 802.11x wireless networks.
LO3 Configure, test and secure industry standard enterprise layer 2 and layer 3 devices in both IPv4 and IPv6 enviromnents.
LO4 Use industry standard tools to verify correct operation and/or fault find a network
