In today's world, Web Technology may be simply characterized in a variety of descriptive ways by the user. However, many users are completely unaware of the fact that when the WWW was initially developed. The evolution of the Web requires starting the history from the beginning when it was presented first. In late 1989, Tim Berners-Lee introduced the Web. He considers the opportunities that what World Wide Web can bring in the era. Tim Berners- Lee introduced the World Wide Web which is expressed by three revolutions that are technically associated in three phases: the Web of Development (Web1.0), Web of People (Web2.0), and Web of Data (Web3.0).
The World Wide Web has gone through several stages of development during its existence. According to the ongoing evolution trend, the Web is currently slowly but steadily transitioning to a more data-centric phase in the framework of Web version 3.0.
The World Wide Web is a network of interconnected hypertext texts that may be accessed over the Internet. A browser is used to view internet sites that may contain the word, photographs, videos, and other forms of content, as well as to navigate amongst them using hyperlinks. Tim Berners-Lee, a British computer engineer, and previous CERN employee proposed what would ultimately become a World Wide Web on March 12, 1989. The 1989 proposal was intended for a more efficient CERN communication system, but Berners- Lee soon realized the notion could be used globally.
Berners- Lee and Belgian software engineer Robert Cailliau proposed utilizing hypertext in 1990 to "connect and retrieve information of various sorts as a web of links in which the user may browse at any moment." In this manner, the first web service was established and tested, and it was later confined to the World Wide Web.
Web 1.0 was the initial web implementation, and it ran from 1989 until 2005. It is defined as a network of information linkages. Tim Berners-Lee, the inventor of the World Wide Web, considers the Web to be "read-only". Web 1.0 relates to the earliest stage of the evolution of the World Wide Web. Previously, there were just a few content providers in Web 1.0, with the vast majority of users being content consumers. Individual web pages were prevalent, primarily consisting of static sites hosted on ISP-managed web servers or free web hosting providers.
Web 1.0 is a content delivery (CDN) that allows for the display of information on websites. It is appropriate as a personal blog. It compensates the user depending on the number of web pages seen. It has directories where users may search for specific information. It offers very little interactivity in which consumers may exchange information with one another, but it was not feasible to communicate with the website. The web's function was primarily passive. Web 1.0 techniques include HTML, HTTP, and URI, which are essential web protocols
Web 1.0 site includes these four essentials characteristics:
· They have material that can only be read.
· Create a web appearance and make their data available to everyone at any time.
· It contains static web pages and employs basic Html Language.
Major Limitations of Web 1.0
· Web 1.0 pages are only understandable by humans (web readers); they lack machine-compatible content.
· The webmaster is entirely responsible for keeping users up to date and managing the website's content.
· Lack of dynamic representation, i.e., only static information was available for acquisition and no online console was provided for executing dynamic events.
Web 2.0 is the second-gen of the internet. Dale Dougherty characterized it as a read-write web in 2004. The idea was born during a brainstorming session at a conference between O'Reilly and Media Live International. Web 2.0 technologies enable the gathering and management of enormous worldwide populations with mutual interests in social interactions.
Web 2.0 refers to websites throughout the world that emphasize user-generated content, accessibility, and connectivity for end-users. Web 2.0 is also known as the participatory social web. It does not relate to a change in any technological specifications, but rather to a change in the way Web sites are built and utilized. The transition is good, although it does not appear to be the case while the changes take place. Web 2.0 allows interaction and cooperation with one another in social media discourse as the creation of user-generated content in an online world. Web 2.0 is a more enhanced form of Web 1.0.
Web 2.0 site includes these characteristics:
Users can obtain and categorize information collectively when it is sorted freely.
· Dynamic content that reacts to human interaction.
· Through review and online discussion, the flow of information between both the webmaster and site visitors.
· APIs were created to facilitate self-use, such as by a software programmer.
· Web access raises concerns that range from the typical Number of internet users to a broader range of users.
Major limitations of Web 2.0
If a new technology fulfills the expectations of the general public, there is a probability that it will confront a slew of external repercussions that will suppress or restrict the flow of innovation in presenting achievements that are not achievable and will harm the effectiveness of the tech as a whole. There are some limitations of Web 2.0 below:
· Continuous iteration cycle of service changes and updates.
· Ethical concerns around the development and use of Web 2.0.
· Interconnectivity and knowledge exchange across community borders between platforms is currently restricted.
Web 3.0 is one of the most recent and evolving themes linked with the Web 2.0. Web 3.0 was invented by John Markoff of the New York Times in 2006, who proposed it as the third generation of the web. Web 3.0 is also known as the "executable Web." The core idea behind web 3.0 is to organize data and link it to improve search, automation, connection, and reuse across several applications. It is capable of improving data management, facilitating mobile internet access, simulating creativity and invention, encouraging globalization phenomenon, increasing consumer happiness, and assisting in the organization of interaction on the social web.
The Semantic Web (3.0) claims to establish "the world's information" in a more rational manner than Google can ever do with their current engine schema. This is especially true from the standpoint of machine conceptualization as opposed to human comprehension. The Semantic Web needs the use of a formal ontological language, such as OWL, to generate domain-specific theories that machines may use to reason about information and draw new conclusions, rather than merely matching keywords.
Web 3.0 site includes these characteristics
· Semantic Web
· Artificial Intelligence
· 3D Graphics
Major limitations of Web 3.0
Vastness: The World Wide Web is vast, with billions of pages. Data redundancy may occur because we have not yet eliminated all semantically redundant words.
Vagueness: This occurs from the vagueness of questions, of ideas represented by content producers, of matching query words to supplier terms, and of trying to merge disparate knowledge bases with covering somewhat distinct concepts.
Inconsistency: These are logical inconsistencies that will inevitably occur during the growth of powerful ontologies and when separate ontologies are combined.
Deceit: This occurs when the information's producer purposefully misleads the information's consumer.
