How Web Application Process?
Web applications operate using a client-server model. In this system, the client, often a web browser, sends a request to the server. The server processes this request, gathers the necessary data from a database, and returns a response. The client then takes this data and displays it as a web page, allowing the user to interact with the information. This process ensures that users can access and engage with dynamic content on websites in a smooth and efficient way.
Key Components of a Web Application
Client-Side: Normally this uses web standards languages including HTML, CSS, and Javascript. HTML is used to define the structure and content of web pages. CSS styles the pages, determining their appearance. JavaScript adds interactivity and dynamic behavior to the pages, making them more engaging for users.
Server-Side: Programming languages such as Python, Golang, Ruby, PHP, Java, and Node.js are used to handle the server-side logic. Web servers like Apache HTTP Server and Nginx manage incoming requests and responses. Databases such as MySQL, PostgreSQL, and MongoDB store and manage the data that web applications rely on.
