Сharacteristics of Web 1.0, 2.0 & 3.0

Hi! Today I want to speak about such things as Web 1.0, 2.0 & 3.0. Here you will find some of their  characteristics.

Web 1.0 

Web 1.0 refers to the first stage of the World Wide Web evolution. Earlier, there were only few content creators in Web 1.0 with the huge majority of users who are consumers of content. Personal web pages were common, consisting mainly of static pages hosted on ISP-run web servers, or on free web hosting services.

Web 2.0   
The Internet is very much alive and kicking the first generation. Sites primarily gave information but with the rise of sites like Facebook and Amazon the web has become increasingly interactive. It's mostly the user produces the content without contributors. Meanwhile most people have become familiar with web 2.0 blogging, tagging, social networking and social bookmarking. It has paved the way to a next step in the development of the web, the step to the intelligent and omnipresent web 3.0. 

Web 3.0

Web 3.0 is not totally different from the web we know now. It is in many respects a continuation of existing techniques think of the so-called recommender systems that make a personal approach by a website. Possibly amazon has cleverly used this system for a long time now by offering their clients products that other people with the same interest bought before them and on last.fm you can listen online to music that caters  to your personal wishes by using smart systems. These sites are in a continuous learning process and they anticipate what their users like or dislike.

The Internet is a web full of appliances that communicate with each other by exchanging information as more and more everyday appliances are connected to the Internet.  So, now the Internet contains almost all your personal data.
