When you search from your phone or computer, a simplified view of a webpage appears in your browser. This process involves clients and servers: clients are devices like your smartphone or laptop, while servers store website and app data. When a client makes a request, the server sends a copy of the webpage to the client’s device, displaying it in the browser or app. Just like physical objects, web pages have their own languages, structures, and behaviors, requiring specific programming languages to create and optimize them.
