To display other types of information, such as sound and moving images, Internet Explorer needs other programs, or helper applications. To tell Internet Explorer which helper application to use for a given file type, select Preferences from the Options menu. Then select File Helpers from the Receiving Files heading. Web documents are written in Hypertext Markup Language. HTML tags are placed around the document text, to define its logical structure, include graphics, and link it to other documents.
Browsers use HTML tags to display documents properly.
To see the HTML tags in a Web document, select Source from the View menu. Think of a URL as you would a telephone number or an address that connects you to a person or place. The directory doesn't appear this time, and the file name is welcome.html The URL of your current document is displayed in the Address text box at the top of the Internet Explorer window. Type URLs exactly. Be very careful with punctuation and capitalization.
