What CS 372 is about

The theme of CS 372 is “How Computer Networks Work”.  We will begin with an overview of the basic concepts of networking technologies.  We will then delve deeper into these concepts by exploring networking functionality at each of the layers of the Internet Protocol Stack.  Along the way, we will learn about the hardware and software that enable network communication, the protocols that control network communication, and some of the applications that make it possible for the general public to use and enjoy the Internet.

Computer networking is complicated.  There is an enormous body of knowledge that encompasses multiple areas of specialization.  We will attempt to handle the complexity by concentrating on theory, abstractions, and general concepts, and then using a few example technologies to illustrate the concepts.  In addition, we will have some hands-on lab experience to reinforce the concepts.

CS 372 is an introduction to computer networking.  As such, it is mostly theoretical, with some hands-on lab and programming work.  It offers an overview of several aspects of networking (breadth), with details about a few networking technologies (depth).  It can be a first step in earning certification in networking.

CS 372 is not a network administration course.  It is not a certification course in any area of specialization.  Additional courses are required in order to qualify for a CNA/CNE.

The university catalog description for CS 372 is:

"Computer network principles, fundamental networking concepts, packet-switching and circuit switching, TCP/IP protocol layers, reliable data transfer, congestion control, flow control, packet forwarding and routing, MAC addressing, multiple access techniques."

The prerequisites for this course are CS 261 and CS 271 or equivalents.
