The course will cover basic concepts of computer networking for students taking up computer science as their minor. The topics covered include the history and architecture of the Internet, popular applications, congestion control protocols, routing and switching, wireless networking. The course will also rouch upon some recent advances in the field of computer networking.
Textbooks: You may find the following textbooks useful to better understand the concepts taught in class, and for practice exercises. The course roughly follows the content structure of the textbook by Kurose and Ross.
