Moving on to web 2.0, it is now gaining more popularity among web development community. Web 2.0 makes the user experience with any web page richer and faster.
Many think web 2.0 as a new standard or protocol, which is yet to come. But the reality is Web 2.0 is the implementation of latest technologies to evolve highly user-friendly web applications. Using advanced rich Internet applications or RIA such as Ajax, Adobe Flex etc., users can feel a new level of Internet experience. Ajax stands for Asynchronous JavaScript and XML. Ajax technology combines the power of JavaScript and XML to produce highly user friendly web pages.
A user who uses a web page developed using these technologies is able to complete a specific task with less time than using a web application developed using traditional technologies and avoids frequent calls to server. The turn around time is usually less for applications developed using web 2.0 concept. This is because almost everything is done on the client side only. This means that users don’t have to wait for the response from server side on every action completed resulting in saving lot of time.
Web 3.0 is a new and modern era of web. In this part of article, I’ll discuss about the main aspects of Web 3.0 and the main differences between Web 2.0 and Web 3.0
While many people are still trying to find out what is Web 2.0, scientists and major IT companies are discussing what will be the third generation of the Web.
The Web 3.0, also known as Web Semantics, it will be capable of analyzing and connecting all the information available on the internet. The web pages will be prepared to be read by people but also by machines, eventually we will stop searching by keywords, internet will be a place of data (data that writes data) instead of a place of documents.
For this to happen it will be important the combination of programming languages and technologies like RDF (Resource Description Framework), OML (Ontology Web Language) and XML (extensible Markup Language), this combination will allow the machines to analyze, understand and use all the information available on the web.
t will take some years for the Web 3.0 to be implemented, browsers will have to be improved, it will be necessary more complex databases, it will be almost like a second level of information, underneath the web, the boundary between desktop and web will be broken. The Web 3.0 will have more mathematics and engineering, the great majority of web sites will be web services.
There are some companies investing in web semantics standards like Yahoo, companies like Polar Rose are improving a method for image searching, Microsoft and Google are going towards 3D technologies. Nobody knows exactly how will Web 3.0 look like, but one thing is certain, it will happen.
It is in course a radical change in the way we create and use the internet, the Web 2.0 took the internet to a different level, today it is a platform of collective intelligence. Web 3.0 will be the materialization of the web as an intelligent agent.
