As its name suggests, the Internet is like an enormous net which holds and connects vast amounts of information.
Links are present on almost every page of the Internet.
A link is a word or a line of text which is distinguished from the rest of the page either by its color or underlining. Graphics and icons are becoming an increasingly common form of link. Any time your cursor switches from an arrow to a small hand, you know you're at a link. Performing this action is like opening a door into a new room, or web page. This is possible because the link connects two pages by referencing the new page's address.
