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.

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

Attributes Developed
Appreciate how network protocols are layered and how they operate together to perform common communication functions;
Demonstrate a thorough understanding of the main protocols (TCP, IP, etc.);
Understand the main operational characteristics of Ethernet and wireless networks;
Be familiar with the use of the RFC protocol specifications;
Be familiar with the use of network analyser software.
Formulate arguments about network behaviour from an inspection of network packets

Attributes Developed

C - Cognitive/analytical

K - Subject knowledge

T - Transferable skills

P - Professional/Practical skills

Module content

The module content is divided into the following areas:

Introduction to Computer Networks; Local and Wide Area Networks
Layers and Protocols; ISO and TCP/IP models
Application Layer; Web services – the HTTP protocol
Transport Layer; Addressing
Network Layer; Routing
Link / Physical Layer; Data communications – Ethernet, WiFi, ADSL, Physical Addressing
The IP datagram protocol, the Address Resolution Protocol, PPP and DHCP
The TCP protocol – flow control and retransmission methods
Electronic mail and file transfer - SMTP, POP, IMAP and FTP.
Network monitoring and ethical issues of monitoring network traffic
An introduction to network security - methods, vulnerabilities and uses of encryption.

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


Students will be expected to spend a minimum of 2 hours per week on self-study in order to prepare, complete and reflect on lab exercises.

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.
