Today, the increasing use of the Internet among businesses and individuals is affecting the way businesses operate. This will lead to the widespread adoption of web applications as companies move from traditional models to cloud-based and grid models. Web applications provide businesses with the ability to organize activities, increase efficiency, and reduce costs. So what is a web application? What is the difference between a website and a web app? Please read this article to answer the question.




1. What is a web application?

A web application is a computer program using a website browser and web technology to perform tasks over the Internet.

2. Overall

Millions of enterprises use the Internet as a media social to save money. It allows businesses to communicate with the target market and make transactions quickly and safely. However, these activities are effective when enterprises can capture and store all the essential data and have facilities to process all information, then proceed to present the results for users.

A web application uses a combination of server-side scripts (PHP and ASP) to handle information storage and retrieval, and client-side scripts (HTML and JavaScript) to show user information. This allows users to communicate with enterprises by online forms, content management systems, shopping carts, and so on. Otherwise, apps also allow employees to create a document, share information, collaborate on projects, and work with common documents regardless of places or devices.

3. How does web application work?

Web applications are typically coded by language by browser-supported like JavaScript and HTML so these languages are based on browsers to render execution programs. Some dynamic apps require processing on the server-side while static applications need absolutely no server-side processing. The web application requires a web 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 web applications work:

  • The user activates the request to the web server over the Internet, through the web browser or the user interface of the application.
  • The Web server forwards this request to the appropriate web application server.
  • The Web application server performs the requested task - such as querying the database or processing data - and then produces the results of the requested data.
  • The web application server sends the results to the webserver with the requested information or processed data.
  • The web server responds to the client with the requested information which then appears on the user's screen.

4. Web application’s examples


Web applications include online forms, shopping carts, word processors, spreadsheets, video and photo editing, file conversion, file scanning, and email programs like Gmail, Yahoo, and AOL. Common applications are Google Apps and Microsoft 365.

Google Apps for Work have Gmail, Google Docs, Google Spreadsheet, online storage, and so on. Other functions are sharing information and online calendars. This allows all the members in a group access to the same version of the document at the same time. 

5. The benefits of web applications

  • 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 restrictions.
  • They reduce piracy in subscription-based web applications (eg SaaS)
  • They reduce costs for both the enterprise and the end-user, the reason: the business does not need support and maintenance for these web applications, not to mention they do not require a high requirement on the end-user computer to have executable.

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

In fact, the boundary of a website and web application is fragile. A new site -https://hachinet.com/blogs is an instance, to readers, it is a website. But on the admin and editor’s side, it is a web application. Besides, some websites have the ability to provide search and comment for users, still a website, not a web app.


Currently, the increase in using the Internet in companies and individuals have taken a toll on business activities. This led to the widespread adoption of web applications when the company moved from the traditional model to the cloud-based model and the grid pattern (grid). Web applications provide businesses the ability to streamline the operations, increase efficiency, and reduce costs. 

Online apps like email clients, word processors, spreadsheets, and other programs all have the ability to offer the same function as the desktop version of the software. However, they have the advantage of being able to work on multiple platforms, have a wider reach, and are easily accessible anytime, anywhere.
