            Search Engine

            If you want any information on any topic for which you do not know the URL or

            address, you can get the information through a search engine.

            A search engine is a program that searches through the collection of web pages for
            particular information. It allows users to enter any keyword for which it displays a list

            of websites with related information.
            Many search engines use a program called spider

            to display a list of all web pages that contain the
            word or phrase you entered. A spider reads pages

            on websites in order to create a catalog or index
            of hits. A hit is any web page name that lists as a
            result of a search.

            Some popular search engines are Google, Bing, and Yahoo.
