Hello Ajaykumarmeher:
Hopefully I can explain Web 2.0 in layman's terms without deviating into the its technical aspects.
Web 2.0 is an idea that can be acquired inexpensively through the advancement of interactive software, whether you use someone's server (the means to get onto the internet with specific capabilities, or pay for your own server and create you own interactive site.)
The capabilities of Web 2.0 "makes you more productive - it makes the web faster through a program called AJAX - more accessible through RSS feeds allowing material to be published in more than one area at the same time in more than one format." (RSS feeds are important in publishing and news).
* It makes blogging publishing easier, allowing more optional use of such things as "widgets" that can be easily interfaced on your site in seconds for personal interaction at no expense, which normally required...a technical web master.
Web 2.0 gives you such options that facilitate what you wish to do with your site, while encouraging social interaction and options that can keep your people coming back to your sight because you have given them great reason to do so. -- (Similiar to the web master's programing of one stop shopping without the major expense.)
Widgets such as the following can easily be added with just a click of the mouse:
- A clock for your customers convienance.
- A Music Search Box.
- Health Search Box.
- A Polling Box for whatever you desire to poll.
- A live Weather report.
- The Top News of the Day or any top category subject you believe pertinent.
- A Yedda Widget allowing interaction as we are doing now.
Web 2.0 can help you to be "more productive" doing the things you love or the things you normally do on-line. ... like multiple shopping on Amazon.com or the ability for interaction in the area of book reviews.
Allows the capability for "personal interaction comments" to posts on blogs or the encouragement for social interaction like message boards.
For now, software toolkits and their use are inexpensive and cost effective for startups. A prime example is "Blogging Sites."
It allows for the feeling of "immediate gratification" because of the interaction options provided. --- Wikipedia is one example.
Bottom line is: these sites using Web 2.0 idea's have so many technologies available that both the owners of the sites benefit financially and from options that bring and keep traffic, as well as the surfers who now have more options that can be found at one site, making those sites of more value on both ends.
"It gives power to the people quickly and efficiently. Where as the former sites are the polar opposite." ... technically and individually more involved and a higher cost factor.
* It's the continued growth and improvement of the internet capabilities and its sites for more and better idea options through the willingness of individuals to participate along the way on both sides of the issue ... technical and participation.
A prime example for your review is TypePad.com, which provides all the technological program support and options, while providing a huge knowledge base written in easy to understand language with samples allowing one to create a professional looking blogging site ... cost effectively without a webmaster.
For the end result view of the above Web 2.0 capability visit the Jane Doe Chronicles at: www.janedoechronicles.typepad.com ... From nothing came easily, something of professional value.
Hope you will find this a good start in your non-technical understanding of what Web 2.0 is.
