#####The WEB

In 1989, while researching at CERN, British scientist Tim Berners-Lee created the world wide web (www). This technology was invented to address the demand for automatic data sharing between scientists at universities and research establishments around the world<sup>[[1]]</sup>. The term _“WEB”_ is an acronym for _“World Wide Web”_, and it refers to the collection of all internet resources and users who use the hypertext transfer protocol (HTTP)<sup>[[2]]</sup>.
 
The web has progressed over time, with numerous versions, spanning from one (1.0), two (2.0) and the third version (3.0).![versions](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/sr42on699an99sjmq4kc.png) The third version, which is currently in the implementation phase, has seen low developers adoption; however, widespread adoption is only now beginning for users of this technology<sup>[[3]]</sup>.

You might be asking why there are several types and what do they all mean. As a result, this article will help by shedding more light on the various versions, the differences between web 2 and web 3.

#####Web 1.0 – Version 1.

The initial stage of the World Wide Web’s advancement is referred to as _“Web 1.0”_. In Web 1.0, there were just a few content creators, with vast majority of users being content users. Personal web sites were common, and they mostly consisted of static pages hosted on ISP-owned web servers, or on free web hosting services.  Advertisements on websites while surfing the internet were prohibited in Web 1.0. In addition, Web 1.0 is a content delivery network (CDN) that allows for the presentation of information on websites. Its pages were built using server side or Common Gateway Interface (CGI). It also charges the user based on the number of pages viewed. It had directories that allowed users to retrieve a specific piece of information.


It is worth of note that the major drawback with this version was it inability for users to interact with the web pages because they were static and the only form of interaction was through instant messenger (such as yahoo, AOL, etc.), and chat rooms. This version lasted between, 1989 – 2004. Due to the above limitations web 2.0 was developed

#####Web 2.0 – Version 2.
Web 2.0 refers to websites around the world that use user-generated content, usability, and interoperability for end users. Web 2.0 is also known as the participative social web. It does not refer to a change in any technological specification, but rather to a change in the way web sites are built and used. The transition is beneficial but it does not appear to be the case while the changes take place. Web 2.0 allows interaction and collaboration with one another in a social media dialogue as the creation of user-generated content in a virtual community. Web 2.0 is a more advanced version of Web 1.0.

Web 2.0 development takes advantage of web browser technologies such as AJAX and JavaScript frameworks. AJAX and JavaScript frameworks have recently gained popularity as a technique of constructing web 2.0 sites.

The Web 2.0 appears to be a welcome response to a web users demand to be more involved in what information is available to them.

#####Web 3.0 – Version 3.
Web 3.0 is a term that is used to describe many evolutions of web usage and interaction among several paths. In this, data is not owned but instead shared, where services show different views for the same web. It refers to the evolution of web utilization and interaction, which includes altering the web into a database. <sup>[[3]]</sup>




``Please note`` that W3 refers to www or world wide web, while web3 refers to the generation of the technology.
