Web search refers to the process of using a search engine to find information on the internet. Users enter keywords or phrases into a search box, and the search engine returns a list of relevant web pages, images, videos, or other content. Popular search engines include Google, Bing, and Yahoo. Search engines use algorithms to rank results based on relevance and quality. They index billions of web pages, allowing users to quickly access a vast amount of information. Web search is a fundamental tool for research, learning, and everyday inquiries in the digital age.
