ELI5: Explain Like I'm 5

search engine

Search engines are like librarians for the web. They help you find things on the web by looking through all the websites and sending you the information you asked for. To use a search engine, you type in a few words that you are looking for and then click the search button. The search engine will then go and look through all the websites on the web and find the information you asked for. It will then put the most relevant results at the top and list the others below in order of importance.
