Instructor for the course EG-101 Computer Networks (Spring 2021) - It is a core course for all 1st year iMtech students. The main aim of this course is to make the students familiarise and understand how the heterogenous networks are interconnected and information flows from source to the destination. Further, this course delves into various protocols involved in transmitting packets efficiently from one end of the globe to the other end via internet. Towards this end, various network applications and their underlying protocols are discussed. Basics of socket programming enables students to understand the connection between application layer to transport layer for reliable delivery of data. State-of-the-art congestion and flow control algorithms for flow of information over the Internet are also taught. Existing routing algorithms concepts for information flow are covered. Medium access control protocols and how an information moves steps by step to reach the final destination is finally discussed.
