Networking by Kunal Kushwaha
I just completed the networking video by Kunal I was very surprised by what a detailed video is that I learned from basics.
His video was very beginner friendly and his teaching style was also good.
I learned many topics from his video: the OSI model, the history of networking, CSA, protocols, etc.
