What is Search Engine?

A search engine is a software system that helps users find information on the internet by discovering, indexing, and ranking web content. It uses automated programs called crawlers to scan websites, collect data, and store it in a searchable index. When a user enters a query, the search engine analyzes keywords, intent, and relevance to deliver results on a search engine results page. Modern search engines also use algorithms, artificial intelligence, and personalization to improve accuracy. They can return webpages, images, videos, maps, and news, helping people quickly access reliable information and navigate the vast online world every single day
