• User Interaction: It all starts when a user opens a web browser and enters a web address or clicks on a link to a specific web application.
• Sending a Request: The web browser sends a request to a web server. This request includes the URL (Uniform Resource Locator) of the web application.
• Web Server Processing: The web server, which hosts the web application, receives the request. It processes the request and determines what content or data needs to be retrieved or generated. This content can include web pages, images, videos, or any other information stored on the server.
• Server-Side Processing: If the web application is dynamic, it often involves server-side scripting. This means that server-side scripts, written in languages like PHP, Ruby on Rails, or Python, generate the necessary content. For example, if a user is logged in, the server will retrieve their personalized data from a database.
• Database Interaction: In many cases, web applications interact with a database to retrieve or update information. This could be user account data, product listings, messages, and more. The server communicates with the database to retrieve or store the relevant data.
• Response Generation: Once the server has processed the request and gathered the necessary data, it generates a response. This response is typically in the form of HTML (Hypertext Markup Language) for web pages, but it can also include CSS (Cascading Style Sheets) for styling and JavaScript for interactivity.
• Sending the Response: The server sends the response back to the user’s web browser, usually in the form of HTML, along with any associated resources like images or stylesheets.
• Client-Side Processing: The user’s web browser receives the response and processes it. It renders the web page and executes any JavaScript code for interactivity. This allows users to interact with the web application, submit forms, click buttons, and perform various actions.
• Displaying the Web Page: The final result is displayed on the user’s screen as a fully functional web page. Users can see the content, interact with the application, and get the information or services they are seeking.

Web applications can be designed to work seamlessly across different devices and web browsers. They offer users the convenience of accessing services or information from anywhere with an internet connection. The process of requesting, processing, and delivering information is at the core of how web applications function, making them an integral part of our digital lives.
