A web application is a program that runs on a remote server and can be accessed through a web browser. Let’s explore the key aspects of web applications:

Definition:

A web application, also known as a web app, is application software that users access using a web browser.

Unlike traditional desktop applications that are installed locally on a user’s computer, web applications reside on a remote server and are accessed over the World Wide Web.

Users interact with web applications through their browsers, making them compatible with most standard computers and operating systems.

Characteristics:

Server-Side Execution: Web applications are executed on the server, not on the user’s device. The server processes requests and sends back the appropriate responses.

Client-Side Interaction: Users interact with web applications using their browsers. The browser renders the content and executes client-side scripts (such as JavaScript) to enhance interactivity.

Dynamic Content: Web apps can deliver dynamic content based on user input, database queries, or other external data sources.

Authentication: Many web applications require user authentication to access personalized features or secure data.

Examples: Webmail services, online shops (e-commerce), social media platforms, content management systems, and more.
