Course Aims and Objectives
The Internet is one of mankind's supreme achievements, certainly no less magnificant than the Great
Pyramid at Giza or the Apollo Space Program. In this module, we aim to introduce you to the Internet,
its architecture and features, and its main protocols. The Internet's protocols enable it to be used
for communications between distributed entities, and we will explore some of these in depth, seeking to
understand how they work, and why they take the form they do. In doing so,
we will draw on Shannon's Theory of Communication, itself an impressive achievement.
This module will provide an important foundation for the third-year module COMP315:
Technologies for e-Commerce.
To introduce networked computer systems in general, and the Internet in particular:
- The basic principles that govern their operation,
- The design and organisation principles of successful computer networks,and
- The key protocols and technologies that are used in the contemporary Internet.
Upon completing this module, you should:
- Understand the basic theoretical principles of computer communications networks
(eg the notion of bandwidth, Shannon's law, etc)
- Understand how the notion of layering and abstraction apply to the design of
computer communication networks
- Understand the structure and function of the OSI/ISO seven layer model of
- Understand the organisation of the Internet, and
how this organisation relates to the OSI seven layer model
- Understand the principles of the key protocols that govern the Internet.
While we will mention the OSI/ISO 7-Layer model, most of our focus will be on the simpler North American
This table presents the provisional structure for the course, and may change as the semester progresses.
We will be following a top-down approach
to the protocol stack, as presented in the text book by Kurose and Ross. Most other textbooks, including
Tanenbaum, follow a bottom-up approach.

I encourage you to visit the web-sites for these textbooks, and make use of the student resources
you find there.
- Coursework: 20 %
The coursework will consist of 2 programming assignments worth 10% each.
- Final Exam: 80 %
The exam will be 2 hours long. Calculators
will not be necessary and will not be permitted.
the exam consists of two parts:
Part A is multiple choice and accounts for 25% of your exam mark.
In part B, you will be asked to answer 3 questions out of 4. Each
question will be worth 25% of the total marks for the exam. Questions will include a mix of book-work and
problem-solving, as in last year's exam paper.
