World Wide Web
n. (abbr. web or WWW)
the massive collection of information and services accessible over the Internet through the Hypertext Transfer Protocol (HTTP)
the servers and network infrastructure used to store and deliver web-based information and services
World Wide Web is often used interchangeably with Internet. However, the Internet is the larger network on which the web resides. The web is commonly associated with browsers, such as Firefox, Internet Explorer, Netscape, and Opera. Because browsers often provide the ability to access information and services using other protocols, such as File Transfer Protocol (FTP) and Gopher, non-HTTP services are often considered to be part of the web.
