Web Evolution

Web Evolution is the phases through which the web, the Internet server system for supporting specially formatted documents, has developed. Web documents are formatted in a markup language called HyperText Markup Language (HTML) that supports links to other documents, graphics, audio, and video files. Thus far, the web has undergone three phases.

Web 1.0

Web 1.0 was the first stage of the evolution. It ran roughly from 1990 to 2005 and was about open protocols that were decentralized and community-governed. Most of the value accrued to the edges of the network. There were only a few content creators in Web 1.0, the majority of users were consumers of content. Static, personal web pages hosted on ISP-run web servers or by free web hosting services were common. Content was served from the server’s file system. Advertisements on websites were banned. Users used online digital photography websites to store, share, view, and print digital pictures. In this stage, the web was a content delivery network for showcasing pieces of information on websites. It costs users per pages viewed and relied on directories for users to retrieve a particular piece of information.

Web 2.0

Web 2.0 encapsulates the current worldwide interoperability of the participative social web. The height of Web 2 ran roughly from 2005 to 2020. It works via siloed, centralized services run by corporations, such as ICANN, and most of the value goes to Google, Apple, Amazon, and Facebook. Web 2.0 is not technologically different from Web 1.0; it is an enhanced version. Web 2.0 refers to the 21st-century Internet applications that transformed the digital era following the dot-com bubble. Its web browser technologies include AJAX and JavaScript frameworks. It permits the collective retrieval and classification of information and dynamic, user-responsive content which flows between the site owner and site users often through evaluation and online commenting. Web 2.0 is characterized by many online tools, platforms, and applications that encourage end-user interaction, such as podcasting, blogging, tagging, RSS curating, social bookmarking, networking, media, and content voting.

Web 3.0

Web 3.0 began in 2021 and refers to the novel development of the backend of the web, as opposed to Web 2.0, which focuses on the frontend. The web3 era combines the decentralized, community-governed ethos of web 1.0 with the modern functionality of web 2. Web 3 is the internet owned by the builders and users and orchestrated with tokens. Data may not be owned but shared. Web 3 has been called the "Semantic Web," because it necessitates the use of a declarative ontological language to produce domain-specific ontologies that machines can use to reason about information and make new conclusions, not simply match keywords. In Web 3.0, computers should be able to distinguish information to provide faster, more relevant results. The 3D design is also part of 3.0 websites and services. Information will be more connected due to semantic metadata, content will be accessible by multiple applications, and with IoT, every device can become connected to the web. Web3 research focuses on provable security, cryptography, and privacy; consensus and optimization of decentralised algorithms; cryptoeconomics and game theory; networking; and behavioral economics.
