Question

List at least 3 technologies that are provided by Web2 and select one of them to explain in detail.?

Answer 1

Communication and information technologies, hosted by web-based interfaces, which allow users to contribute, share, and collaborate with others via the Internet. The content generated by Web 2.0 technologies is always based on collaborative effort from their users, as opposed to the first generation Web applications that creates the content by individual sources.

Some technologies provided by Web2 are

The client-side (Web browser) technologies used in Web 2.0 development include Ajax and JavaScript frameworks. Ajax programming uses JavaScript and the Document Object Model (DOM) to update selected regions of the page area without undergoing a full page reload. To allow users to continue interacting with the page, communications such as data requests going to the server are separated from data coming back to the page.

1) Marketing

Web 2.0 is used by companies, non-profit organisations and governments for interactive marketing. A growing number of marketers are using Web 2.0 tools to collaborate with consumers on product development, customer service enhancement, product or service improvement and promotion. Companies can use Web 2.0 tools to improve collaboration with both its business partners and consumers. Among other things, company employees have created wikis Web sites that allow users to add, delete, and edit content to list answers to frequently asked questions about each product, and consumers have added significant contributions.

Another marketing Web 2.0 lure is to make sure consumers can use the online community to network among themselves on topics of their own choosing. Mainstream media usage of Web 2.0 is increasing. Saturating media hubs like The New York Times, PC Magazine and Business Week with links to popular new Web sites and services, is critical to achieving the threshold for mass adoption of those services.User web content can be used to gauge consumer satisfaction. In a recent article for Bank Technology News, Shane Kite describes how Citigroup's Global Transaction Services unit monitors social media outlets to address customer issues and improve products.

2) Education

Web 2.0 could allow for more collaborative education. For example, blogs give students a public space to interact with one another and the content of the class.Some studies suggest that Web 2.0 can increase the public's understanding of science, which could improve governments' policy decisions. A 2012 study by researchers at the University of Wisconsin-Madison notes that "...the internet could be a crucial tool in increasing the general public’s level of science literacy. This increase could then lead to better communication between researchers and the public, more substantive discussion, and more informed policy decision.

3) Criticism

Critics of the term claim that Web 2.0 does not represent a new version of the World Wide Web at all, but merely continues to use so-called Web 1.0 technologies and concepts.First, techniques such as Ajax do not replace underlying protocols like HTTP, but add a layer of abstraction on top of them. Second, many of the ideas of Web 2.0 were already featured in implementations on networked systems well before the term Web 2.0" emerged. Amazon.com, for instance, has allowed users to write reviews and consumer guides since its launch in 1995, in a form of self-publishing. Amazon also opened its API to outside developers in 2002.Previous developments also came from research in computer-supported collaborative learning and computer supported cooperative work (CSCW) and from established products like Lotus Notes and Lotus Domino all phenomena that preceded Web 2.0. Tim Berners-Lee, who developed the initial technologies of the Web, has been an outspoken critic of the term, while supporting many of the elements associated with it. In the environment where the Web originated, each workstation had a dedicated IP address and always-on connection to the Internet. Sharing a file or publishing a web page was as simple as moving the file into a shared folder.

4) Web APIs

Web 2.0 often uses machine-based interactions such as REST and SOAP. Servers often expose proprietary Application programming interfaces (API), but standard APIs (for example, for posting to a blog or notifying a blog update) have also come into use. Most communications through APIs involve XML or JSON payloads. REST APIs, through their use of self-descriptive messages and hypermedia as the engine of application state, should be self-describing once an entry URI is known. Web Services Description Language (WSDL) is the standard way of publishing a SOAP Application programming interface and there are a range of Web service specifications.
