1. The Internet & the WWW

The Internet is a vast collection of thousands of interconnected networks across the world, all of which use the TCP/IP protocol (transmission control protocol/Internet protocol). This common protocol acts as a global electronic language, allowing dissimilar computers to talk with each other easily. The Internet is used for many types of communication--text, graphics, email, audio, video, telephony, and television--by means of thousands of software applications or programs, the most popular and widely used of which is the Web browser. The Internet is the network. The World Wide Web is a network application.
