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.

- 2Indexing: The search engine reads and analyzes the text, images, and keywords on discovered pages, storing them in vast centralized database indexes.
- 3Ranking & Serving Results: When you type a query (e.g. "CCC exam admit card 2026"), complex algorithms evaluate hundreds of factors (page relevance, domain authority, speed) and return the best matching search results on the SERP (Search Engine Results Page) in fractions of a second!
