The Internet is a group of networks tied together to form an infrastructure for communication.
The terms Internet and World Wide Web (WWW) are often used interchangeably, but they are quite different. The Internet, a massive public medium established in the mid-1960s, is an interconnected web of networks and computers that work together to provide worldwide communication. The World Wide Web, which uses Hypertext Transfer Protocol (HTTP), is just one of the services the Internet offers. Many other services are offered, such as e-mail, which uses Simple Mail Transfer Protocol (SMTP) for communication, and file transfer, which uses File Transfer Protocol (FTP). The Web is a method of accessing information through the Internet by using HTML hyperlinks. It uses Web servers, Web browsers, and Web pages to communicate information through the Internet network.
