Namespace:

A namespace is a container which allows us to put the relevant classes, functions, objects etc. all together and helps us to make our programming better by allowing disambiguation of homonym items.

As per the rule of namespace we cannot assign same name to more than one class/function/namespace. For many modern computer/programming language a namespace is a context for identifiers.  Java uses this concept as package, C++ combines namespace and process names which is called as name mangling.
