HIERARCHICAL EXAMPLE.
Many examples of hierarchical addressing exists which reduces the amount of work needed in locating or in delivering,and one of such examples is the 'sorting of books in a library'.
Looking at a library having books kept randomly on any stack and shelf,it will make it difficult finding any book easily or locating any book of a specific genre.so,to avoid such problems, books are orderly sorted in a library and each book is given or has a unique identification number.
Books that has the same or related subject are kept in the same stack and books of the same genre are also kept together.
In a library,there are many stacks having different rows.
Take for an example; If one need to find a book on computer network,the user can search for the books in stacks of books that are related to Computer Science instead of searching the whole library for the book.
So,the hierarchical addressing saves lots of work and also time required for searching a specific book in the library.
