The reason why the web application is being used the most in today's time is that it can be used on many platforms because it is not an operating system based but a web browser program.

What is Web Application?

Web application is a software or program that we can access using any web browser and in simple words, it is also like computer software or application but it runs on the web server so that it can be used in our system. There is no need for extra space to do this.

If we talk about web application, then the best examples are Facebook, YouTube, twitter etc., which are used by everyone and if we talk about designing a web application in this way, then scripting language is used for this, in which server Languages ​​like PHP and ASP are used as side scripting, and JavaScript and HTML are used for similar client-side scripting.

How does web application work?

Web applications are usually coded in the language the browser supports, such as JavaScript and HTML, because the language itself depends on the browser to make the program workable. And these are dynamic applications that require server-side processing while others are completely static and never require any processing on the server.

Apart from this, the web application requires a web server to manage the requests received from the client and to perform these requests or requested tasks, an application server and sometimes a database is needed to store the information. In which application server technology is used from ASP.NET, ASP and ColdFusion to PHP and Node.JS.

In this way, see how a web application processes, some steps are given below, from which you will be able to understand its function better.

Step 1. The user first triggers a request to the web server through the user interface of the web browser or application on the internet.

Step 2. Now the web server forwards this request to a suitable web application server.

Step 3. Now the web application works as per the request of the server like querying the data or processing the data and then generating the result or result of the requested data.

Step 4. Now the web application server sends the result to the web server along with the requested information or processing data.

Step 5. The web server then responds to the client with the requested information which is then visible on the user's screen.
