In mathematics, a limit point of a set S in a topological space X is a point x that can be approximated by points of S in the sense that every neighbourhood of x with respect to the topology on X also contains a point of S other than x itself. Note that x does not have to be an element of S. This concept profitably generalizes the notion of a limit and is the underpinning of concepts such as closed set and topological closure. Indeed, a set is closed if and only if it contains all of its limit points, and the topological closure operation can be thought of as an operation that enriches a set by adding its limit points.

Unfortunately nobody can be told what the Null is…
Null is the value that we can not define. This is special value used in db that is given to the field when no value was assigned. In practical life we can consider it as no value. It is not zero, it is not letter or any other character this is something that can not be used.Null meaning & definition 6 of Null.

When a variable has no value, it considered to be Null. Having a Null value is different than having a value of 0, since 0 is an actual value. However, when used in a boolean test, both Null and zero result in a FALSE value. Programmers often use boolean tests to determine whether a variable has been given a value or not.
