Difference Between Web 1.0, Web 2.0, and Web 3.0

Web 1.0 was all about fetching and reading information. Web 2.0 is all about reading, writing, creating, and interacting with the end user. It was famously called the participative social web. Web 3.0 is the third generation of the World Wide Web, and is a vision of a decentralized web, which is currently a work in progress. It is all about reading, writing, and owning.

Let's dive deeper to know better about the features and need of Web 1.0, Web 2.0, and Web 3.0.

What is Web 1.0?  

Web 1.0 refers to the first stage of the World Wide Web evolution. Earlier, there were only a few content creators in Web 1.0 with a huge majority of users who are consumers of content. Personal web pages were common, consisting mainly of static pages hosted on ISP-run web servers, or free web hosting services. 

• Web 1.0 refers to the early phase of the web, roughly from 1991 to 2004. Advertisements were banned on websites while surfing the internet.
• Platforms like Ofoto allowed users to store, share, view, and print digital photos.
• Web 1.0 worked mainly as a content delivery network (CDN) used to display information on websites, including personal pages. Users were charged based on the number of pages they viewed, and directories helped them retrieve specific information.

Four Design Essentials of a Web 1.0 Site Include:

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

Features of the Web 1.0

• Easy to connect static pages with the system via hyperlinks
• Supports elements like frames and tables with HTML 3.2
• Also has graphics and a GIF button
• Less interaction between the user and the server
• You can send HTML forms via mail
• Provides only a one-way publishing medium

What is Web 2.0? 

In 1999, Darcy DiNucci coined the term "Web 2.0," which gained fame in 2004 at the First Web 2.0 conference (later Web 2.0 Summit) organized by Tim O'Reilly and Dale Dougherty. Web 2.0 is an enhanced version of Web 1.0, also known as the participative social web.

• Core Focus: Emphasizes user-generated content (e.g., blog posts, videos, reviews), usability (intuitive interfaces for all users), and interoperability (sites working seamlessly with each other via APIs and data sharing).
• Not Technical: Refers to changes in how web pages are designed and used, not technical specifications (e.g., shifting from static HTML pages to dynamic, user-editable platforms like wikis or social networks).
• Key Features: Enables interaction, collaboration, and social media dialogue in virtual communities (e.g., commenting, sharing, co-editing content in real time on platforms like YouTube, Wikipedia, or Facebook).
• Transition: Beneficial but gradual, without a clear moment of change (e.g., evolved through tools like blogs in the early 2000s, RSS feeds, and AJAX, improving engagement without a single "switch" event).

Web browser technologies are used in Web 2.0 development and it includes AJAX and JavaScript frameworks. Recently, AJAX and JavaScript frameworks have become very popular means of creating web 2.0 sites. 

Features of the Web 2.0 

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

Usage of Web 2.0

The social Web contains several online tools and platforms where people share their perspectives, opinions, thoughts, and experiences. Web 2.0 applications tend to interact much more with the end user. As such, the end-user is not only a user of the application but also a participant in these 8 tools mentioned below:

• Podcasting
• Blogging
• Tagging
• Curating with RSS
• Social bookmarking
• Social networking
• Social media
• Web content voting

What is Web 3.0?

Web 3.0 describes the evolution of web usage and interaction across multiple paths, upgrading the backend after Web 2.0's frontend focus.

• Backend Shift: Transforms the web into a readable/writable database; integrates Distributed Ledger Technology (DLT) like blockchain for decentralized, tamper-proof storage and transactions (e.g., Ethereum storing data across nodes instead of central servers).
• Smart Contracts: Self-executing code on blockchain that automates agreements based on user-defined conditions (e.g., a freelance payment releases only when work is verified, no intermediaries needed).
• Data Model: Users retain control/ownership of data via wallets or keys; platforms access it permissionally and compose customized views (e.g., one dataset powers a social feed, NFT marketplace, and analytics dashboard differently for each service).
• Contrast to Web 2.0: Web 2.0 enhanced user experience via frontend tools (AJAX for async updates, folksonomy tagging, social APIs); Web 3.0 rebuilds the infrastructure layer for decentralization, trustlessness, and programmable data flows.

The Semantic Web (Web 3.0) aims to organize the world’s information in a more meaningful way than current search engines. It focuses on machine understanding rather than human interpretation. To achieve this, it uses declarative ontological languages like OWL to create domain-specific ontologies, allowing machines to reason about data and draw new conclusions instead of just matching keywords. 

Web 3.0 is the latest and updated version of the web. Their are many different concepts and new things in this version if you wish to learn about the new frameworks and how to develop the website that use web 3.0 technology then you should checkout our full stack node course.

Features of the Web 3.0

• 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.
• 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.
• 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.
• 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.
• Ubiquity: Content is accessible by multiple applications, every device is connected to the web, and the services can be used everywhere.
• DLT and Smart Contracts: With the help of DLT, we can create a virtually impossible-to-hack database that gives real value to digital content and virtual ownership. This technology enables a trustless society by using smart contracts that work automatically without needing a middleman, relying only on data stored in the DLT. It is a powerful tool that can improve the world and create more opportunities for everyone on the internet.
