COMPUTER NETWORKING - 2021/2

Module Overview

Computer networks are an essential part of almost all corporate computing facilities and even most domestic ones.  Interoperability is the key – all components must conform to the same hardware and packet specifications in order that they can be interconnected successfully.  This module introduces essential concepts about all the computer networking layering levels with some emphasis on the routing algorithms and implementation of network sensing.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

·         Their understanding of the communication networks over the internet and the limitations involved by implementing the sensing and testing criteria.

·         Their ability to design an efficient means of computer networking considering all the pros and cons.

 

Thus, the summative assessment for this module consists of:

·         An individual coursework exercise and accompanying report. This assesses LO2, LO3, LO5 and LO6.

·         A 2 hour closed-book examination during the exam period. This will assess LO1, LO2, LO3, LO4 and LO6.

 

Formative assessment and feedback:

Formative feedback is provided as part of the feedback for the summative assessment as well as during the lab sessions.

Module aims

• This module provides a grounding in how computers are interconnected using a variety of networking components.  Then, it also shows how software protocols provide access to the network from higher-level applications. The student should also understand in how to sense the network and how the check the parameters involved in network communications.

Learning outcomes

Methods of Teaching / Learning

44 contact hours in weeks 1-11, consisting of:

• 2 hours of lectures per week


• 2 hours of labs per week

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
