Abstract
This concluding chapter presents the concepts in digital electronics and fundamental concepts in information and communication theory and showed that these seemingly diverse concepts have led to a new form of communicating, embodied by the Internet. It introduces the fundamental notions that define the transmission of digital information in communication systems. The integration of digital communication networks with the computer given birth to the global Internet. Examination of bandwidth and channel capacity of a transmission link or trunk suggested that bandwidth could be traded for noise in a transmission system. As popular as AM and FM are for analog transmission, so is pulse code modulation (PCM) for digital signaling. The fact that several pulses are needed to code each sample increases the bandwidth. PCM allows repeated noise-free regeneration of the original digital signal, which implies that a digital signal can be sent over large distances without deterioration. The World Wide Web is the leading information retrieval service of the Internet. Browser software such as Netscape Navigator and Internet Explorer allows users to view retrieved documents and Web pages from the Internet.
