    Learning Objective

    1. Explain how four networking technologies—the Internet, the World Wide Web, intranets, and extranets—make data communication possible.

    In addition to using networks for information sharing within the organization, companies use networks to communicate and share information with those outside the organization. All this is made possible by data communication networks, which transmit digital data (numeric data, text, graphics, photos, video, and voice) from one computer to another using a variety of wired and wireless communication channels. Let’s take a closer look at the networking technologies that make possible all this electronic communication—in particular, the Internet (including the World Wide Web), intranets, and extranets.
