Tim Berners-Lee created the World Wide Web in 1989 at CERN.[5]
The primary goal in the development of the Web was to fulfill the automated information-sharing needs of academics affiliated with institutions and various global organizations. Consequently, HTML was developed in 1993.[6]
Web 1.0 is described as the first paradigm wherein users could only view material and provide a small amount of information.[7] Core protocols of web 1.0 were HTTP, HTML and URI.[8]
Web 2.0, a term popularised by Dale Dougherty, then vice president of O'Reilly, during a 2004 conference with Media Live, marks a shift in internet usage, emphasizing interactivity.[9][10]
Web 2.0 introduced increased user engagement and communication. It evolved from the static, read-only nature of Web 1.0 and became an integrated network for engagement and communication. It is often referred to as a user-focused, read-write online network.[7]
In the realm of Web 2.0 environments, users now have access to a platform that encourages sharing activities such as creating music, files, images, and movies.[11] The architecture of Web 2.0 is often considered the "backbone of the internet," using standardized XML (Extensible Markup Language) tags to authorize information flow from independent platforms and online databases.[7]
Web 3.0, considered the third and current version of the web, was introduced in 2014. The concept envisions a complete redesign of the web. Key features include the integration of metadata, precise information delivery, and improved user experiences based on preferences, history, and interests.[citation needed]
Web 3.0 aims to turn the web into a sizable, organized database, providing more functionality than traditional search engines. Users can customize navigation based on their preferences, and the core ideas involve identifying data sources, connecting them for efficiency, and creating user profiles.[7]
This version is sometimes also known as Semantic Web.[12]
