Welcome

Welcome to the wonderful and fascinating world of computer networks!!!

This course will explore the fundamentals of computer networks. We shall study various aspects of data transfer from point A to point B in today’s Internet. We shall begin the course with a general overview of data networks and a discussion of protocols, and the TCP/IP protocol suite.

We shall then briefly study the key aspects of transmission, interfacing, link control and multiplexing. Important concepts of wide area networks (WAN) like circuit and packet switching, routing and congestion control will be studied. Finally, we shall look into the IP, TCP and Application layers of the protocol stack.

Overall, this course shall leave you with a broad overview of computer networks and a strong grasp over the fundamentals of computer data networks. We will briefly study certain key concepts of wireless networks and a few state-of-the-art wireless technologies as well. I shall walk you through the various layers of the TCP/IP model and familiarize you with the issues/concerns/importance of every layer. We shall take the bottom-up approach meaning that we shall begin at the lowest layer and work our way up the protocol stack.
