In contrast, desktop applications usually require users to download and install updates manually, which can be time-consuming and inconvenient.

How Web-Based Applications Work

Web-based applications follow a client-server architecture. When a user interacts with a web-based application, the web browser acts as the client, sending requests to the server hosting the application. The server processes the requests, retrieves data from databases or external APIs, performs necessary calculations or operations, and sends the response back to the client.

Web-based applications utilize a combination of front-end and back-end technologies. The front-end, also known as the client-side, comprises HTML, CSS, and JavaScript, which are responsible for rendering the application interface and handling user interactions. The back-end, or server-side, involves technologies such as server-side scripting languages (e.g., Python, PHP), databases (e.g., MySQL, PostgreSQL), and web servers (e.g., Apache, Nginx) to handle data processing, storage, and application logic.
