Web Application is a type of program which runs inside a Web Browser and helps the user or client to interact with the Web Server to perform the required tasks.

In simple words, any application which is running in a Web Browser (Google Chrome, Firefox, Safari, etc) is called a Web Application. The Web Application can be a simple calculator or a big E-commerce website.

Now that we have a basic understanding of Web App. It’s time to take a deep look at the working of it.

How does a Web Application Work

Every Web Application consists of two parts, which are the Front-End and Back-End of an Application.

Front-End is responsible for the overall looks of an Application. Without Front-End, it is not possible to use the application.

So, it is a part of a Web App that helps the user in interacting with the Program. Like – Button, Menu, Form, etc.

The languages which are used for creating a Front-End of a Web App are HTML, CSS, and JavaScript which are called Client-Side Scripting Languages.

On the other hand, Back-End is responsible for managing the Client requests and Database. Without Back-End, our application will not produce any result.

So, it is a part of a Web App that is responsible for doing all the calculations, automation, and making our application dynamic.

The languages which are used to create a Back-End of a Web App are PHP, Python, Ruby, Java, and many more. These types of languages are also called Server Side Scripting Languages.

So, the Web Applications that use Server or Server Side Scripting Languages are called Dynamic Web Apps.

On the other hand, the Web Apps that do not use Server or Server Side Scripting Languages are called Static Web Apps.

So, the Front-End and Back-End of a Web App interact with each other to produce the required result.

The interaction between Client and Server is performed in the following 5 steps:

  1. User or Client sends the query or request to a Web Server with the help of Web Browser.
  2. Web Server then forwards this query to the appropriate Web Application Server.
  3. Web App Server then executes the requested query, generates the output, and stores that output in the database.
  4. Then Web Application Server sends the generates output back to the Web Server.
  5. At last, the Web Server sends the output of the query as a result on the web browser or client.

Web Application vs Website

Since one website can contain multiple Web Apps. So, there is not much difference when it comes to a Web App and Website.

A Web Application is usually dynamic as it requires user interaction or input to process. On the other hand, a website is generally static as it doesn’t require any input from the client-side.

The working and development of a Web App is very complex and requires a good knowledge of the Front-End as well as Back-End.

On the other hand, working and developing a Website is quite easy and doesn’t require much knowledge as compared to Web App.

Websites are not much User Friendly or Engaging as compared to Web Applications.


There are several benefits of using a Web Application. Some of them are as follow:

  1. Since Web App is a Browser-Based Application. So, it is platform-independent and can run on any Operating System (Windows, Linux, OS X) or Device (PC, Mac, Mobile, Tablet).
  2. Web Applications are present in the Web Server. So, we don’t need to install the application on our computer and we can directly use it with the help of a Web Browser.
  3. From a developer perspective, Web Apps are comparatively Cheap. As we just have to create a single version of our Web App and it can run in all the Operating System and Hardware Devices.
  4. Since all the users use the same version of the Web App. So, it reduces the compatibility issues of an Application.
  5. With the help of Subscription-based Web Apps, Software Piracy can be controlled.


Some of the Best Examples of Web Applications are:

  1. Amazon
  2. YouTube
  3. Pinterest
  4. Netflix
  5. Google Analytics
  6. Forbes
  7. Twitter
  8. Dropbox
