These notes are completely for educational purposes and not for any commercial purpose. They are my understanding of Computer Networks which I have written in the form of tutorials. I have taken references from Wikipedia and my class notes. Also, I would recommend you to read Data Communications and Networking (4th Edition) by Behrouz A. Forouzan if you want deeper insights into the concepts of Computer Networks.
