What is Null?
This was intended as a meme but is actually a good representation of what "Null" is. In C#, when you declare string s = "My shit"; it means that "s" is a reference to a memory location that holds the data "My shit". string s = null; means that the reference "s" exists but it's not pointing to any object, as in it holds nothing.

ELI5: What is Null?
Suppose I send you a letter and ask you a question. a) If you send me back the letter with nothing written on it --> empty string b) If you don't send anything back --> NULL EDIT: To incorporate what u/glutier said: In scenario a, I would be able to compare your answer with others (and maybe group you with others who have no opinion on the matter). Whereas in scenario B, I cannot assume anything about your response and therefore cannot compare you to anyone. More on reddit.com
