When you tell your computer to bring you the Tutorial from the SFU Faculty of Education's server, that's what it does. It's important to understand that navigating the Internet involves nothing more than telling a computer where to find the file you want. The World Wide Web, aka the web, is made up of websites . Webpages are just ordinary computer files with a few tags added to tell your computer how to display the content. The magic of the web is hypertext , also called linked text .
Links can be text or images, and can be anywhere on a page.
Text that's linked is usually underlined and of a different color . But links can be almost invisible. Sometimes the file you've requested isn't on our server, but on one in, say, Australia. The computer can still retrieve that file, but it may take a second or two longer.
