Hello People, today I am going to list some networking concepts that are essential when we want to start into security. This is more like a personal blog, and I am no expert into networking, I am just trying to set bare minimum topics we should all have some idea to understand what actually happens behind the screen ( in networking ).

So the list will not be exhaustive, also not in order, but it will be more of essential topics we should learn, and read from various sources to understand the very fundamentals.
Also the list below is not a compilation but something what I thought to learn , so the list keeps getting populated as I discover new topics, any suggestions or changes are always welcome through comments or Social-channels.
