Introduction: The Internet has transformed society, opening up communication channels never dreamed of by previous generations. This course introduces students to the structure, design, and operation of the Internet, beginning with the electronic and physical construction of networks and basic network protocols. It addresses personal safety online, how email and Web browsers work, and the design of simple Web pages. Along the way it explores the historical and societal implications of this new medium.


Optional / also recommended (on reserve in Young library):

      • How The Internet Works, by Preston Gralla: Contains detailed labeled diagrams of many internet-related topics.
      • Basics of Web Design by Terry Felke-Morris: Contains detailed information on web page design and specific aspects of HTML, aimed at beginners. The more advanced portions of this book will also be useful if you take CSC 105.
      • Web 101, by Wendy Lehnert and Richard Kopec, which was used for this course in previous semesters.

In addition to the texts above, Wikipedia usually contains accurate information focused on specific topics relating to the Internet.

Important !!! Announcement about Self Scheduled Exam: I have just  learnt that, self-scheduled exams are not available for the half-term classes. (I think in the past, it was possible to give at the end of the semester, but it seems this does not work well). So, the best thing we have is applying the final project for all. Also we can talk about the case in the next class (monday).

Announcement about Last Class: We have a class at Oct 26 (Wednesday).
