Internet: the backbone of the Web

The World Wide Web (WWW) is a vast sea of documents (web pages) that interconnect so that you can jump from one page to the next. It is a network of information resources. The Web relies on three mechanisms to make these resources readily available to the widest possible audience:

  1. A uniform naming scheme for locating resources on the Web, e.g., URL.
  2. Protocols for access to named resources over the Web, e.g., HTTP.
  3. Hypertext for easy navigation among resources, e.g., HTML.
