Key difference: The Internet is the massive global system that connects computer networks around the world together. Millions of private, public, academic, business, and government networks worldwide connect with each other over the internet to share massive amounts of information, resources and services. WWW stands for the World Wide Web. It is also sometimes known as W3. It is a system of linked hypertext documents that can be accessed via the Internet. WWW is also often referred to as the Web and is wrongly used as a synonym for the Internet.

The Internet is the massive global system that connects computer networks around the world together. Millions of private, public, academic, business, and government networks worldwide connect with each other over the internet to share massive amounts of information, resources and services. Internet is what we use to access web pages, send e-mails, listen to music or watch videos online. It hosts an extensive range of information, one that we generally take for granted today.

The Internet uses the standard Internet protocol suite (TCP/IP) to allow us to connect to the net. It has numerous information resources and services, such as the web pages of the World Wide Web (WWW), games, videos, images, e-mail, social networking, etc. It has even spawned new services such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). The Internet is currently being used by billions of people worldwide.

The Internet carries information from all streams; traditional, such as newspaper, book and other print publishing; and modern such as blogging and web feeds. It also enabled new forms of human interactions through, instant messaging, e-mail, Internet forums, and social networking. It has gained so much popularity that in fact almost all forms of business communication as well as personal happens online through e-mail, instant messaging and social networking. With phone calls and text messaging (SMS) coming is second.

WWW stands for the World Wide Web. It is also sometimes known as W3. It is a system of linked hypertext documents that can be accessed via the Internet. WWW is also often referred to as the Web and is wrongly used as a synonym for the Internet. The Internet and the WWW are quite different from each other. The hypertext documents, which in addition to text can also include images, videos, tables and other multimedia files can be viewed using web browsers such as IE, Chrome, Firefox, etc. The hypertext documents are often connected through a series of links, also known as hyperlinks. The pages can be navigated using these links. The documents are formatted in a markup language known as HTML (Hypertext Markup Language) and supports links to other documents.

The World Wide Web was originally a concept created by computer scientist Sir Tim Berners-Lee that allowed easy sharing of documents and other research. He was frustrated with having to access a variety of different serves in order to refer to other research and created the hypertext system known ENQUIRE to help make it easier to find the research he needed. The formal proposal for the World Wide Web was published on 2 November 1990 by Berners-Lee and computer scientist Robert Cailliau. The proposal defined using hypertext "to link and access information of various kinds as a web of nodes in which the user can browse at will.” Though originally, it was launched as a read-only web, it then slowly evolved to the web that allowed users to create and publish their own websites and this is the one we know now. The WWW uses client server architecture. It allows the client to access any documents that are stored in hypertext format on a server using an application, known as web browser. Though there is no clear distinction whether the www is actually required when trying to access a document, it is related to the internet where it is a norm to begin a website with www.

The World Wide Web is essentially one of the ways that information can be shared over the Internet. It is just one aspect of the Internet. The Internet is vaster than just the Web. The Web is basically just the web pages that we can access from the browser. Other than the Web, the Internet can also be used for e-mail, which relies on SMTP, Usenet news groups, instant messaging and FTP.
