I will illustrate the concept of namespaces with a simple example:
When typical parents choose names for their children, they ensure that all the names are different. They don't want to call one name and get two answers!
But, they don't care if their children have the same names as children in other families.
The family is a namespace. When they call out a name, it's heard all over that 'space' but not in other 'spaces'.
