The rate of evolution in the VoIP market would surely make Darwin’s head spin and the latest entry into this market would probably blow his mind. The recently-launched Ribbit company bills itself as “Silicon Valley’s First Phone Company.” Like Skype, Ribbit’s system supports softphones, but unlike Skype Ribbit isn’t a closed system. An interesting issue is that being based on Flash/Flex technology no installation is required as it is completely Web-based - an interesting and potentially powerful advantage over Skype.

Web application, or webapp, in software engineering is an application which is accessed via Web over a network, like an intranet or the Internet. Also, it is a computer software application that has been coded in a browser-supported language (like ASP, HTML, Perl, PHP, etc.). It is reliant on a common web browser to enable the application to become executable.
Because of the ubiquity of a client, web applications have become very popular, sometimes they are called “a thin clientâ€. One other key reason for their popularity is the ability to update and maintain the Web applications without the need to distribute and install software on potentially thousands of client computers. Some of the most common Web applications are Webmail, online auctions, online retail sales, discussion boards, wikis, MMORPGs, Weblogs, and many other functions.

One major difference of web application use from traditional application use is the inherent delays in navigating from one web application page to another. These delays are typically caused by network traffic and computation. It takes more time to serve the pages to the browser if the web server is on a distant network and computing data (calculations, data-sorting, etc.) also prolongs the waiting time for web application users. Fortunately, there are some ways through which users can lessen the delays which specifically result from working on a public network:
• Control the infrastructure by making an intranet rather than using the public internet.
• Using smaller graphics and lesser pages can minimize page loading time.
• Reduces errors and overall task time by making navigation easier and clearer.

Knowing the difference between the application and the browser can greatly aid users in easy Web navigation. Always remember that the browser is the one which displays the data on each page and that a back button is normally found in it. This button, when clicked, re-displays the pages, but it does not mean that the current state of the application is being reversed. Likewise, clicking the Forward button is also not the same with having to do a Redo command on the application. Hence, users must be provided with links or toolbars and menus within the application to allow them to easily navigate according to the task they need to perform.

Web applications are normally more complicated than desktop applications and users can easily get lost in the huge amount of information displayed to them. Luckily, there are ways in which web applications can be structured to help easy navigation:
• Arrange information - Try linking all pages on the site to each other and provide links to important information on your site.
• Use navigational aids - A clear and consistent page design can help users track where they are and where they can go from their current location.
• Create a unique URL for each page - A unique URL for each page lessens the hassle of losing unsaved data caused by reloading pages.
• Use hypertext indexes and help systems - This can help users manage tasks by giving them quick access to information and help guides.

1. Provide a Query Interface - One of the basic functions of web applications is to provide users with an interface for inputting data. The data is termed as a “query” or a “request” because this user-defined data is used to ask or make a request from a service on the web server machine.
2. Transmit User-Defined Query - The user-data is sent to a web server once it is received.
3. Perform Server Side Processing - The web server processes the user-data which it has received through a “middleware”.
4. Massage Data - The user-defined request indicates how the data should be processed.
5. Transmit Query Results - The processed data is now sent back to the client
6. Perform Client Side Processing - The sent data is displayed to the user.
