The best place to start is the “Web” of Web 3. The World Wide Web is not the Internet. Think of the Internet as the communication protocol that stores and sends digital information. What is the digital information? The web page itself ( media, hyperlink, and formatting) is the digital information that gets sent along the Internet. You can think of the Web as the layer that functions on top of the Internet (This “layer on top concept” will also be found in crypto protocols). You and I use the Internet to interact with the Web page. The Web page was made by a web designer on another computer somewhere else in the world. It was stored on a server and sent to your computer via the Internet. The versions of the web are not like software updates, but more like milestones to mark the evolution of Web pages.

TCP/IP

Web 0: ARPAnet

If you don’t care about how the internet was invented, then you can probably skip to Web 1.

We’re going to start the history of the Internet and the World Wide Web with the Cold War. The Soviet Union launched Sputnik in 1957, this beach ball sized satellite circled the earth and sent radio transmissions back to earth. Immediately afterward, the American government had two focused concerns: (1) Single points of failure - What if the Russians could attack a single weak point and bring down an entire infrastructure? (2) Domestic science and technology capacity - Are we producing enough scientist and technologists to ensure national security?

One significant single point of failure was the national telephone system. If the existing “circuit switching” model were compromised, it would disrupt the flow of information between military bases. In 1962, a scientist named Joseph Licklider proposed a solution to this problem: The “Intergalactic Computer Network” - computers that could talk to one another. Such a network would enable government leaders to communicate even if the Soviets destroyed the telephone system.

The US Department of Defense established the Advanced Research Projects Agency (ARPA) to manifest the proposal.

~~Historically, voice and data communications were based on methods of circuit switching, as exemplified in the traditional telephone network, wherein each telephone call is allocated a dedicated, end to end, electronic connection between the two communicating stations. The connection is established by switching systems that connected multiple intermediate call legs between these systems for the duration of the call.The traditional model of the circuit-switched telecommunication network was challenged in the early 1960s by ~~~~Paul Baran ~~at the RAND Corporation, who had been researching systems that could sustain operation during partial destruction, such as by nuclear war. He developed the theoretical model of distributed adaptive message block switching.~~[15] ~~However, the telecommunication establishment rejected the development in favor of existing models. ~~Donald Davies ~~at the United Kingdom's ~~National Physical Laboratory ~~(NPL) independently arrived at a similar concept in 1965. Packet Switching is the process by which a networking or telecommunications device accepts a packet and switches it to a telecommunications device that will take it closer to its destination. Packet switching allows data to be sent over the telecommunications network in short bursts or “packets” that contain sequence numbers so that they can be reassembled at the destination. Wide area network (WAN) devices called switches route packets from one point on a packet-switched network to another. Data within the same communication session might be routed over several different paths, depending on factors such as traffic congestion and switch availability.

Web 1: Read Only

If you already think of Web 1 as a content delivery network, then you can probably skip to Web 2.

In 1989 a physicist named Tim Berners-Lee submitted a vague but exciting proposal for an information management system. He proposed to build on the hypertext (text that was clickable and would bring the user to another page or file) technology. This existing technology allowed early adopters to create huge databases of interconnected information like the memex automated library. The result were static pages that was connected by hyperlinked text

Four Design Essentials of a Web 1.0 Site Include:

1. Static pages.
2. Content is served from the server’s file system.
3. Pages built using Server Side Includes or Common Gateway Interface (CGI).
4. Frames and Tables are used to position and align the elements on a page.

The era of web1 was roughly 1989 to 2004

Web 2

Five Major Features of Web 2.0:

1. Free sorting of information, permits users to retrieve and classify the information collectively.
2. Dynamic content that is responsive to user input.
3. Information flows between the site owner and site users using evaluation & online commenting.
4. Developed APIs to allow self-usage, such as by a software application.
5. Web access leads to concerns different, from the traditional Internet user base to a wider variety of users.

Web 3

Main features That can Help us Define Web 3.0:

1. Semantic Web 
   The succeeding evolution of the Web involves the Semantic Web. The semantic web improves web technologies in demand to create, share and connect content through search and analysis based on the capability to comprehend the meaning of words, rather than on keywords or numbers.
2. Artificial Intelligence 
   Combining this capability with natural language processing, in Web 3.0, computers can distinguish information like humans to provide faster and more relevant results. They become more intelligent to fulfill the requirements of users.
3. 3D Graphics 
   The three-dimensional design is being used widely in websites and services in Web 3.0. Museum guides, computer games, e-commerce, geospatial contexts, etc. are all examples that use 3D graphics.
4. Connectivity 
   With Web 3.0, information is more connected thanks to semantic metadata. As a result, the user experience evolves to another level of connectivity that leverages all the available information.
5. Ubiquity 
   Content is accessible by multiple applications, every device is connected to the web, and the services can be used everywhere.
6. DLT and Smart Contracts
   With the help of DLT, we can have a virtually impossible to hack database from which one can have value to their content and things they can own virtually, this is the technology that enables a trustless society by the integration of smart contracts which does not need to have a middle man to be a guarantor to make that contract occur on certain cause its based on data from that DLT. It’s a powerful tool that can make the world a far better place and generate more opportunities for everyone on the internet.
