There are some dynamic applications that require server-side processing, while static applications will not require server-side processing at all.

How does a Web Application work?

Web applications require a web server to manage requests from the client, an application server to perform the requested tasks, and sometimes, a database to store information. Application server technologies range from ASP.NET, ASP and ColdFusion, to PHP and JSP.

Here is the flow of how the web application works:

• The user triggers a request to the web server over the Internet, through a web browser or the application’s user interface.

• The web server forwards this request to the appropriate web application server..

• The Web application server performs the requested task – such as querying a database or processing data – and then produces the results of the requested data.

• The web application server sends results to the web server with the requested information or processed data.

• The web server responds back to the client with the requested information which then appears on the user’s screen.

5. Benefits of web application (web application)

• Web applications run on multiple platforms regardless of operating system or device, as long as the browser is compatible.

• All users have access to the same version, which eliminates any compatibility issues.

• They are not installed on the hard drive, thus eliminating space constraints.

• They reduce piracy in subscription-based web applications (e.g., SaaS)

• They reduce costs for both businesses and end users, the reason: businesses do not need support and maintenance for these web applications, not to mention they also do not require high requirements on the end user’s computer to run. enforcement.

6. What is the difference between Website and Web app?

What is the difference between Website and Web application?

It is a fact that the boundary between website and web application is quite fragile. A news site – is an example, for the reader it is the website. But on the admin and editor side, it is a web application. Besides, some websites have the ability to provide search and comment functions for users, but are still just websites, not web apps.

The following is a (relative) comparison table distinguishing between websites and web apps for your reference:
