Of course the arrangement of ones and zeros is complex but it is in that way that the information is able to be transferred from computer to computer. But luckily, you don't need to know anything about how this all works. All the interpretation of the binary code is done by the software you use. The Internet is made up of a vast number of computers linked to each other, mostly over telephone lines, but also by fibre optics, microwaves and even satellites. No one knows how many users of the Internet there are in the world.
Estimates vary widely.
And people use the Internet for many different purposes. Although the terms World Wide Web and Internet are often used interchangeably, the World Wide Web is only one part of what makes up the Internet. Other parts include gopher and usenet. To access the World Wide Web, your computer needs browser software like Netscape Navigator or Microsoft Internet Explorer. For example, Microsoft's Internet Explorer has an additional email component called Outlook Express.
