Using Search Engines and Surfing Websites (सर्च इंजन और वेबसाइट सर्फिंग)
With over 2 billion websites on the World Wide Web, finding specific information—such as a government job notification, syllabus PDF, or train schedule—would be impossible without an automated index.
A Search Engine is a specialized web-based software system designed to search, index, and retrieve information stored on the World Wide Web according to queries entered by users.
1. Popular Search Engines
Google (गुगल): The world's most dominant search engine (founded in 1998 by Larry Page and Sergey Brin). Handles over 90% of global searches.

Indexing: The search engine reads and analyzes the text, images, and keywords on discovered pages, storing them in vast centralized database indexes.
