The search engine is a tool that is used to find digital information. In the past search engines were only able to search the Internet. Today, search engines are able to search the Internet, pictures, videos, maps, documents, and many other things. The search engine is a very important component of the Internet. Without it, there would be millions of web pages, but no way to organize or find what you were looking for. People use search engines to find restaurants, research on topics, or even just for fun.
