Web technology and the way it is used have certainly evolved over the last few years, and each evolution has brought about new tools and techniques relevant to recruiters. These evolutions have popularly been called Web 1.0, 2.0 and 3.0 in the media and now web 4.0 and Web 5.0.

 Let’s dive a little deeper and discover how the web evolved from its inception to what we know it now.

Web 1.0

Web 1.0 was the first stage of the World Wide Web revolution, usually referred to as the read-only web. This was how the Internet we know today started in the first place, where the websites were merely informational and comprised entirely static content; they were only linked together by hyperlinks and lacked any interactive content or design elements.

Moreover, this was the era when only text emails could be written and sent, one could not even upload or attach any images or pictures. Although, personal pages were quite common, consisting mainly of static pages hosted on ISP-run web servers, or on free web hosting services. Interestingly, it cost the user as per pages viewed. It had directories that enabled the user to retrieve a particular piece of information.

In a nutshell, Web 1.0 was a content delivery network (CDN) that enabled to showcase of the piece of information on websites where users passively receive information without being given the opportunity to post reviews, comments, and feedback. The content here was served from the server’s file system and the pages were built using Server Side Includes (SSI) or Common Gateway Interface(CGI). Interestingly, frames and tables were used to position and align the elements on a webpage back then!

According to Tim Berners-Lee the first implementation of the web, representing Web 1.0, could be considered as the “read-only web.” In other words, the early web allowed users to search for information and read it. There was very little in the way of user interaction or content contribution. […]

The first shopping cart applications, which most e-commerce website owners use in some shape or form, basically fall under the category of Web 1.0. The overall goal was to present products to potential customers, much as a catalog or a brochure does — only through a website retailers could also provide a method for anyone (anywhere in the world) to purchase (their) products.

Web 2.0

Web 2.0 was the second stage of the evolution of the web, also called the read-write web and it was the phase when websites grew in terms of user interaction. It was the period when websites became more focused on user-generated content, usability, and interoperability for end-users, leading them to become the – participative social web.

During Web 2.0, terms like blogs, social media, and video streaming gained popularity. This time period is also acknowledged for the ease with which music and video clips could be exchanged. It opened doors to podcasting, blogging, tagging, curating with RSS, social bookmarking, social networking, social media, web content voting, etc. It was the birthplace of Youtube, Wiki, Flickr, Facebook, and so on. Also, blogging became popular with the introduction of WordPress which started as a PHP & MySQL-led blogging platform and has now advanced to become a full content-managed system (CMS) that powers over a quarter of the web and e-Commerce completely revolutionized the way we shop.

Thus, Web 2.0 brought a fundamental shift where people were allowed to share their perspectives, opinions, thoughts, and experiences via a number of online tools and platforms. It brought us the concept – of ‘ Web as Platform ‘, where software applications are built upon the Web as opposed to upon the desktop. This was when websites began using web browser technologies such as AJAX and Javascript frameworks. This period continued to see the origin of APIs(Application Programming Interface) – a software intermediary that allows two applications to communicate with one another.

Web 3.0:
Web 3.0 is one of the modern and evolutionary topics associated with the following initiatives of web 2.0. Web 3.0 was first coined by John Mark of the New York Times and he suggested web 3.0 as the third generation of the web in 2006 [18]. Web 3.0 can be also stated as ―Executable Web‘‘.

The Basic idea of 3.0 is to define structure data and link them in order to more effective discovery, automation, integration, and reuse across various applications [6]. It is able to improve data management, support accessibility of mobile internet, stimulate creativity and innovation, encourage factors of globalization phenomena, enhance customers‘
satisfaction and help to organize collaboration on the social web.
Web 3.0 is also known as the semantic web. The semantic web was thought up by Tim Berners-Lee, inventor of the World Wide Web. A dedicated team at the World Wide Web consortium was working to improve, extend and standardize the system, languages publications and tools have already been developed

Are we there yet??

It seems we had everything we had wished for in Web 2.0, but it is way behind when it comes to intelligence. Perhaps a six-year-old child has/had better analytical abilities than existing search technologies! The keyword-based search of web 2.0 resulted in an information overload.

The following attributes are going to be a part of Web 3.0: Contextual Search

  • Tailor-made Search
  • Personalized Search
  • Evolution of 3D Web
  • Deductive Reasoning

Because we aren’t there yet (completely), developers and users have come up with a ‘cheap’ intermediate way of contextualizing the search problem.

What’s important to understand is that the nomenclature with which we describe should not be taken too seriously. Just because a website does not employ Web 2.0 features does not make it obsolete. After all, a small e-commerce website trying to sell niche products may not have any business need for users to submit content or to be able to interact with each other.

Web 4.0 – “Mobile Web”
The next step is not really a new version but is an alternate version of what we already have. We needed to adapt to its mobile surroundings. Web 4.0 connects all devices in the real and virtual world in real time.

Web 4.0 can be considered as an Ultra-Intelligent Electronic Agent, Symbiotic web and Ubiquitous web. Interaction between humans and machines in symbiosis was the motive behind the symbiotic web. It is powerful as the human brain. Progress in the development of telecommunication, advancement in nanotechnology in the world and controlled interfaces are using web 4.0. In simple words, machines would be clever in reading the contents of the web and react in the form of executing and deciding what to execute first to load the websites fast with superior quality and performance and build more
commanding interfaces.

Web 4.0 will be a read-write concurrency web. It ensures global transparency governance, distribution, participation, and collaboration in key communities such as industry, political, social and other communities. Web OS will be
such as a middleware which will start functioning like an operating system.

Web OS will be parallel to the human brain and implies a massive web of highly intelligent interaction

Web 5.0:
Web 5.0 is still an underground idea in progress and there is no exact definition of how it would be. Web 5.0 can be considered a Symbiotic web, decentralized i.e. it is not possible to have a Personal Server (PS) for any personal data or information stored on the net, and people try to get interconnected via Smart Communicator (SC), like Smartphones, Tablets or Personal Robots i.e. is represented as its own avatar inside the SC, that will be able to surf alone in the 3D Virtual world of the Symbiotic. The Symbiotic servers will be able to use a part of the “memory and calculation power” of each interconnected SC,
in order to calculate the billions and billions of needed data to build the 3D world and to
feed its Artificial Intelligence surf alone.

Currently, the Web is “emotionally” neutral: do not feel what the user perceives. The company Emotive Systems has created
neurotechnology through headphones that allow users to interact with content that meets their emotions or change in real-time facial expressions an “avatar.

Although Web  5.0 still is in developing mode and the true shape is still forming, the first signals are that Web 5.0 will be about a linked web which communicates with us as we communicate with each other (like a personal assistant). Web 4.0 5.0 is called a “symbiotic” web. This Web will be very powerful and fully executed.  

Web 5.0 will be about the (emotional) interaction between humans and computers. The interaction will become a daily habit for a lot of people based on neurotechnology. For the moment web is “emotionally” neutral, which means the web does not perceive the user’s feelings and emotions. This will change with web 5.0 – emotional web.   One example of this is www.wefeelfine.org, which maps the emotions of people. With headphones on, users will interact with content that interacts with their emotions or changes in facial recognition.
