Web Application

A web application is a computer program that uses a web browser to perform a particular function. It is also called a web app. Web apps are present on many websites. A simple example is a contact form on a website.

A web application is a client-server program. It means that it has a client-side and a server-side. The term "client" here refers to the program the individual uses to run the application. It is part of the client-server environment, where many computers share information. For example, in the case of a database, the client is the program through which the user enters data. The server is the application that stores the information.

Benefits of web applications
A web application has many benefits, including:

• You don't need to install it on the hard drive, so it doesn't cause space limitations.
• It requires less support and maintenance from the business and lower technical requirements from the user's computer.
• A web application reduces costs for both the end-user and the business.
• Web applications are always up to date because updates are applied centrally.
• All users can access the same version so it eliminates any compatibility issues.
• You can access web applications anywhere with a web browser.
• As long as the browser is compatible, web applications can run on multiple platforms regardless of the operating system or device.
• Web applications discharge the developer of the responsibility of building a client that is compatible with a specific type of computer or a particular operating system.
• Web applications reduce software piracy in subscription-based web applications.

How a web application works:

• The user creates a request to the web server over the Internet through the application's user interface.
• The web server sends this request to the web application server.
• The web application server executes the requested task, then generates the results of the required data.
• The web application server sends those results back to the web server (requested information or processed data).
• The web server carries the requested information to the client (tablet, mobile device or desktop).
• The requested information appears on the user's display.
