Text Analysis
Differences between the Internet and the World Wide Web Many people use the terms Internet and World Wide Web interchangeably, but in fact the two terms are not synonymous. The World Wide Web uses the HTTP [7] protocol, one of the languages spoken over the Internet, to transmit data. (译文) The Web is just one of the ways that information can be disseminated over the Internet. The Internet, not the Web, is also used for e-mail [8] , FTP [9] , newsgroup [10] and IM [11] . So the Web is just a portion of the Internet, albeit a large portion. The two terms should not be confused.
