The Location field contains the address of each page being viewed. Each page on the web has its own unique URL that identifies its location. Like an address, the URL tells Navigator where to find the page. The protocol tells Navigator which transfer method to use to get the page. Pages typically have filenames that end with an .htm or .html extension.
Navigator loads the page into the browser window and remembers the location of the original page.
This way, if the page's contents change, you can update the page in the browser window by clicking the Reload button in the Navigation toolbar. Most of the information on the World Wide Web is organized in pages that are linked to each other. Pages are located on different computers that are connected to the Internet. When you tell Navigator that you want to look at a particular page, it sends a request for that page to the other computers on the Internet. The network of computers passes the request to the computer storing the page that you want to see.
