What do we call a tool that helps computer users find web pages that match their search requests?

A tool that helps computer users find web pages that match their search requests is known as a search engine. Search engines operate by crawling the web and indexing content from various websites, allowing users to input keywords or queries. The search engine then analyzes this input and provides a list of relevant results based on its indexed information. This process involves complex algorithms that rank web pages according to various factors, such as relevance and authority.

A web browser, while essential for accessing and viewing web pages, does not perform the function of searching for content; it is primarily used for navigating the internet. A database refers to a structured collection of data that can be accessed and manipulated but is not inherently designed to search the web. A URL resolver is a component that translates domain names into IP addresses, enabling internet communication, but it does not facilitate content searching within web pages. Therefore, the correct identification of a tool that aids in finding web pages based on user queries is indeed a search engine.
