Null pointer (sometimes written as NULL , nil , or None ), used in computer programming for an uninitialized, undefined, empty, or meaningless value. Null string, the unique string of length zero

Xenon If you don't know about anything in any language just see their documentation. https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/null#:~:text=null%20(C%23%20Reference)&text=The%20null%20keyword%20is%20a,except%20for%20nullable%20value%20types.

In C# null is to indicate that a reference isn't referencing an object in the heap memory. So it is pointing to nowhere. The possible issues that it can lead to are mostly handled by the Garbage Collector.
