Module 3 - Web 2.0

Web 2.0 versus HTML

When looking at the Internet Communication Blink List page versus the HTML version there are a number of differences. These are as follows:

·       HTML version is much quicker to load up in a web browser

·       The layout of the web 2.0 version has a much more interactive look and feel

·       Web 2.0 version provides more images and allows them to be interactive

·       Web 2.0 Increases practical usage

·       Semantic tagging improves the navigation of web 2.0 version

From the list above you can see that the only downfall with web 2.0 is that it increases traffic due to a larger content volume and the page takes longer to load. Web 2.0 is not a product but a standard which can use tools such as Ajax to develop these web 2.0 standard pages. The main features web 2.0 provides over HTML as described by O’Reilly Media are:

 

·       It uses XHTML instead of HTML which allows it to cross the boundary of more than one web browser;

·       Features include dynamic display and interaction using the Document Object Model;

·       Data interchange and manipulation using XML which is a language to transfer data files;

·       asynchronous data retrieval using XMLHttpRequest;

·       JavaScript binding everything together.
