How Do Search Engines operate?
Let us take an example of a librarian of the books library to understand the term quoted above.
Suppose there is a library of books in the university, college or in a school where different kinds of books containing poetry, science, medicines, marketing, management, computer networks, fine arts etc. are available for the students from a different discipline.
Whenever a student needs a book it will go to the librarian and demands for that specific book.
