Without links the Web would simply not be a "web" but rather a huge collection of isolated individual pages. To connect the pages within a website, we create links. A link, also known as a hyperlink, is the path to another document, to another part of the same document, or to other media such as an image or a movie.
Links are usually displayed as colored and/or underlined text that looks different from the main body of text. As well as linking from text, you can link from an image or another object.
Clicking on a link opens up the corresponding document or web page in the browser window. Links can also open up documents such as PDF documents or they can perform a jump to another place within the same document.
When you hover your cursor over a link, the cursor changes to a pointed finger and the web address of the link appears in the status bar at the bottom of the browser window.
