A search engine is something that is designed to search for information on what we know as the World Wide Web. This information can consist of web pages, images and many other types of files. Some of the search engines can also mine through data that is available in newsgroups, databases and different kinds of open directories. Before we had these things known as search engines, there was just a complete and boring list of all web servers.
