WEB  APPLICATION

      A web application, or web app, is a software program that operates through a web browser, allowing users to access services, data, or tools without requiring installation on their local device. Unlike traditional desktop applications, web apps are accessed remotely via the internet and a web server.

Key characteristics of web applications:

  Browser-based access:

  Users interact with web applications directly through a web browser (e.g., Chrome,   Firefox, Safari), eliminating the need for software installation.

  Remote server storage:

  The application's code and data are stored on a remote server, which processes user requests and sends responses back to the browser.

  Platform independence:

  Web applications are generally compatible with various operating systems and devices, as long as a compatible web browser and internet connection are available.

  Dynamic and interactive:

  They are designed to be interactive, enabling users to input data, perform operations, and receive dynamic content updates.

 Examples:

  Common examples include online banking platforms, e-commerce stores, webmail services, online productivity suites (like Google Workspace or Microsoft 365), and social media platforms.

 How web applications work:

  Web applications typically involve a client-side (front-end) and a server-side (back-end). The client-side, built with technologies like HTML, CSS, and JavaScript, provides the user interface and handles user interactions within the browser. The server-side, which can use various programming languages and databases, processes data, manages application logic, and communicates with the client-side to deliver dynamic content.
