We will concentrate on the part of the Internet known as the World Wide Web . The Web is made up of thousands of Web pages, each containing information about a particular topic. But anyone with access to the Internet can create a Web page, so you will need to be careful because the information on some Web pages might not be accurate. They're connected to one another by hyperlinks. A hyperlink could be a line of text, an icon, or a picture that you can click on with your computer mouse to go from one place on the Web to another.
Hyperlinks are easy to recognize.
Words or lines of text that are hyperlinks will usually appear in blue, although sometimes they are another color. Pictures are also frequently used as hyperlinks. The easiest way to tell if a line of text or a picture is a hyperlink is to move your computer mouse over it. By carefully watching the screen you will see your mouse pointer turn into a small hand. If you see the small hand appear, you'll know you found a hyperlink.
