What is the Web?
The World Wide Web, or simply Web, is a way of accessing information through the use of a medium called the Internet. The Internet is a huge network of networks, a networking infrastructure. Its purpose is to connect billions of devices together, all around the globe, so that they can communicate with one another. Information travels through the Internet in a rich variety of languages called protocols, which allow different devices to speak the same tongue in order to share content.
The Web is an information-sharing model, built on top of the Internet, which employs the Hypertext Transfer Protocol (HTTP) as a basis for data communication. The Web, therefore, is just one of the several different ways information can be exchanged over the Internet: e-mail, instant messaging, news groups, and so on, they all rely on different protocols.
