Course Description

This course only deals with one Information Network, the Internet. We will start by discussion social aspects of the Internet, i.e. its history and governance. We then look at engineering aspects of the Internet. Finally, we study how the technical infrastructure is used in services accessed by the end-user.

Course objectives

On completing this course, students

This course will not be providing students with an introduction to Internet resources. This is covered in LIS566.


There are no prerequisites for this course. However, students should have a curiosity of the Internet in general. They should think of themselves not only as users of the computer networks, but also as having a potential auxiliary rôle in the provision of network access to patrons.

Class structure

Classes will be held on Thursday between 18:40 and 21:00 in the computing lab of the Palmer School. The course will mostly be lecture-based. The instructor will try to make it as hands-on as possible, but on this particular topic the options are limited.

Here is a preliminary timetable and topictable:

An excellent comprehensive, but dated book is Tanenbaum (1996). It is style a bible on the general topic of computer networks. For the student's use, it is too advanced and it covers many a topic that we will not look at, because we concentrate on TCP/IP.

There are now many books that cover TCP/IP. An introductory treatment is Blank (2000). A similar level is Casad (2001). Groth (2001) and Govanus (1999) are more advanced treatments. Comer (2000) provides a comprehensive treatment of Internet protocols.

The instructor will make printed copies of his handouts available for students to scribble on during class.


The bulk of the assessment will be a series of mini-exams held at the start of each class, starting from the third class. Each mini exam will raise one or two factual questions on last week's class. These questions should be straightforward to answer from the material covered in the previous class. The avarage of all mini-exams will count for 75% of the final grade.

The remaining 25% will be based on an essay of about 1500 words maximum. Finding topic of the essay is up to the student. The topic is subject to approval by the instructor. Students are also advised to contact the instructor about the essay, he may have some advice on how to focus the topic properly and what primary sources to use.
