A web application is a software program that runs on a web server and is accessed through a web browser over the internet. Unlike traditional desktop applications, web applications do not need to be installed on a user’s device. Instead, users can interact with them directly using browsers like Chrome, Firefox, or Edge.
Web applications are built using technologies such as HTML, CSS, and JavaScript for the front end (user interface), and languages like Python, Java, PHP, or Node.js for the back end (server-side logic). They rely on databases to store and manage data, and communicate with servers through HTTP/HTTPS protocols.
Common examples of web applications include online banking systems, e-commerce websites, social media platforms, and services. These applications are designed to be responsive, user-friendly, and accessible across different devices such as desktops, tablets, and smartphones.Overall, web applications play a crucial role in modern digital life by providing interactive, scalable, and easily accessible solutions for both businesses and users.
