Internet Has Several Services

-          WWW (World Wide Web)

-          Email

-          Chat

-          Online Payment

-          FTP (File Transfer Protocol)

-          Voice over Internet Protocol (VoIP) and IPTV.

-          Instant messaging and More…..

Among them WWW was the famous and mostly used service, so people thought that WWW as “The Internet”.

Before you learn about Web 2.0, you should know little about Web 1.0.

Web 1.0

It is a service which provides Collection Static Pages (Still pages which never changes its content) with stranded Hyper links (used to link the pages). It used HTML (HyperText Markup Language) to display the web pages such as Text, Images, Videos &…..

So when we had Web 1.0 we used the services separately

Eg : We used – Britannica Online to search about Countries & ……., and Chat with our friends   with Yahoo Massager , and E-mail a letter using Yahoo Mail.

But Web 2.0 Has Changed our lives.

Web 2.0 – (Known as Internet 2)

I would say it as “The Integrated Web  of Internet” – because Web 2.0 has interconnected web services to each other

The Main Technology / Part of Web 2.0 (Web 2.0 is built based on)

1. RIA – Rich Internet Application (Flash, Ajax)
2. SOA – Service Oriented Architecture
3. Social Web

RIA : It is based on “How to bring the user experience of the desktop in to the Web browser” (How  give the desktop feel to the browser)

Eg: Drag & Drop, Shortcut Keys, Graphics…….

SOA : It’s about “How do Web Applications Integrate With Other Applications”

Eg : Feeds (RSS), MashUps (Integrated Web Services), Youtube to facebook to twitter

Social Web : This Mostly Interact with the end user

Eg : Social Networking, Blogging, Wikis

“The term Web 2.0 is associated with web applications that facilitate participatory

1. Information sharing
2. Interoperability
3. User-centered design
4. Collaboration on the World Wide Web.

A Web 2.0 site allows users to interact and collaborate with each other in a social media dialogue as creators (prosumers) of user-generated content in a virtual community, in contrast to websites where users (consumers) are limited to the passive viewing of content that was created for them. Examples of Web 2.0 include social networking sites, blogs, wikis, video sharing sites, hosted services, web applications, mashups and folksonomies.” – Says Wikipedia.
