Digital World
The World Wide Web has become the world’s dominant information systems platform. It is the primary tool billions of people worldwide use to interact with the Internet. The Web was invented by Tim Berners-Lee at CERN in 1989 an idea for a database of hypertext links that would allow people to send data and communicate across a network. Opened to the public in 1991. It was conceived as a “universal linked information system”.
World-Wide Web (also called WWW or W3) is a hypertext-based information system. Any word in a hypertext document can be specified as a pointer to a different hypertext document where more information pertaining to that word can be found.
Refers to all the public websites or pages that users can access on their local computers and other devices through the internet. These pages and documents are interconnected by means of hyperlinks that users click on for information.
The World Wide Web is just one common area for information exchange, facilitated by global computer networks — or the Internet. You connect to this Internet to access the Web, but the Internet is just the connection between countless, separate servers, computers, and devices.
While the Internet has its roots in the 1960s, the World Wide Web was first accessed in 1991, once many of the kinks of networking on a global scale had been worked out.
Although they are intermingled and used together, they are certainly not the same. The Internet could exist without the Web, but the Web as we know it could not exist without the Internet. In simple terms, the Internet is the physical infrastructure on which services like the Web run.
What is WWW composed of?
There are three main ingredients that make up the world wide web. URL (uniform resource locator), which is the addressing scheme to find a document; HTTP (hypertext transfer protocol), which connects computers together; and HTML (hypertext markup language), which formats pages containing hypertext links

Internet Architecture Board (IAB): Oversees the technical and engineering development of the IETF and IRTF. Internet Corporation for Assigned Names and Numbers (ICANN): Coordinates the Internet’s systems of unique identifiers: IP addresses, Protocol-Parameter registries, and top-level domain space (DNS root zone).
Is the World Wide Web bigger than the Internet?
The World Wide Web, or web for short, are the pages you see when you’re at a device and you’re online. But the internet is the network of connected computers that the web works on, as well as what emails and files travel across.
How was the Internet before the World Wide Web?
The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.

How does WWW work step by step?
The domain name server returns an IP address for the server that hosts the Website. The browser requests the page from the Web server using the IP address specified by the domain name server. The Web server returns the page to the IP address specified by the browser requesting the page.
A domain is the name of a website, a URL is how to find a website and a website is what people see and interact with when they get there.
The first page of a website is called the homepage.
An IP address (Internet Protocol address) is a unique numerical marker assigned to every device connected to the Internet.
