<human>:  Explain the difference between a web browser and a search engine.
<bot>: The primary difference between a web browser and a search engine is the purpose they serve. A web browser is designed to display webpages on the Internet, while a search engine is designed to interact with databases and return results. A web browser retrieves the webpages, interprets the code, and displays them, while a search engine searches the databases for the information requested by the user. Through its search results, a search engine provides a summary of the webpages that are most relevant to the query.
