A
search engine is a software system designed to carry out web searches, allowing users to search for information on the World Wide Web.
Examples of Search Engines:
- Google: The most widely used search engine globally, known for its powerful algorithms and extensive indexing.
- Bing: Microsoft's search engine, integrated into Windows and Microsoft products.
- Yahoo!: One of the early pioneers in web searching and directory services.
- DuckDuckGo: A privacy-focused search engine that doesn't track user activity.
- Baidu: The leading search engine in China.
- Yandex: The most popular search engine in Russia.
How Search Engines Work:
- Crawling: Automated bots (called crawlers or spiders) browse the web to discover new and updated pages.
- Indexing: The content found during crawling is analyzed and stored in a massive database (index).
- Ranking: When a user enters a query, the search engine uses algorithms to rank the most relevant results.
- Displaying: The ranked results are displayed as Search Engine Results Pages (SERPs).
