Web 1.0:

1. Static Web Pages: Web 1.0, also known as the “Static Web,” emerged in the early 1990s and was characterized by static web pages that displayed text, images, and hyperlinks but lacked interactivity and dynamic content.
2. Limited User Participation: In Web 1.0, the majority of content was created and published by website owners or developers, with limited opportunities for user participation or collaboration. Websites served primarily as one-way communication channels, with users consuming information passively.
3. Basic HTML: Web 1.0 relied on basic HTML (Hypertext Markup Language) for structuring and formatting web pages, along with simple graphics and multimedia elements.
4. Early Internet Adoption: Web 1.0 laid the groundwork for the widespread adoption of the internet, introducing users to the concept of browsing and accessing information online. However, it lacked the interactivity, user engagement, and dynamic content that would characterize later iterations of the web.

Web 2.0:

1. Dynamic and Interactive Content: Web 2.0, often referred to as the “Social Web” or “Read-Write Web,” emerged in the mid-2000s and introduced dynamic, interactive, and user-generated content. Websites became more interactive and responsive, allowing users to contribute content, share information, and collaborate with others.
2. User Participation and Collaboration: Web 2.0 empowered users to actively participate in content creation, curation, and sharing through social media platforms, blogs, wikis, and other collaborative tools. Social networking sites like Facebook, Twitter, and LinkedIn became ubiquitous, fostering online communities and social interactions.
3. Rich Internet Applications (RIAs): Web 2.0 introduced the concept of Rich Internet Applications (RIAs), which used technologies like AJAX (Asynchronous JavaScript and XML) to deliver responsive and interactive user experiences within web browsers. RIAs enabled features such as drag-and-drop, real-time updates, and multimedia streaming.
4. Personalization and Customization: Web 2.0 platforms offered personalized and customizable experiences tailored to individual user preferences and behavior. Algorithms and recommendation systems were used to deliver targeted content, recommendations, and advertisements based on user data and interactions.

Web 3.0:

1. Decentralization and Blockchain Technology: Web 3.0, also known as the “Decentralized Web” or “Semantic Web,” is the next phase of internet evolution characterized by decentralization, interoperability, and trustless transactions enabled by blockchain technology and decentralized protocols.
2. User Control and Ownership: Web 3.0 aims to give users greater control over their data, identity, and digital assets by leveraging decentralized technologies such as blockchain, smart contracts, and decentralized applications (DApps). Users have ownership of their data and can transact directly with others without relying on intermediaries.
3. Semantic Web and AI: Web 3.0 seeks to enhance the semantic understanding of web content through artificial intelligence (AI) and machine learning algorithms. This allows for more intelligent search engines, data integration, and automated decision-making based on contextually rich information.
4. Interoperability and Interconnectivity: Web 3.0 emphasizes interoperability and interconnectivity between different blockchain networks, protocols, and DApps, enabling seamless data exchange and communication across decentralized ecosystems. Standards such as decentralized identifiers (DIDs) and verifiable credentials facilitate trustless interactions and data portability.

In summary, while Web 1.0 introduced users to the concept of the internet, Web 2.0 revolutionized online interaction and collaboration through social media and dynamic content. Web 3.0 builds upon these advancements by embracing decentralization, user empowerment, and interoperability enabled by blockchain and decentralized technologies.
