How do dynamic web pages differ from static ones?

Dynamic web pages are generated in real-time and can change in response to user interaction, unlike static web pages.

In more detail, static web pages are pre-coded with fixed content that remains the same for every user and every visit. They are typically written in HTML and CSS, and the server sends the same response to every request. This means that the content of a static web page does not change unless a developer manually updates the code. Static web pages are simpler and quicker to develop, and they require less server resources. However, they offer a less personalised user experience and are less interactive.

On the other hand, dynamic web pages are generated on-the-fly based on user interaction or changes in data. They use server-side scripting languages like PHP, ASP.NET, or JSP, in addition to HTML and CSS. When a user requests a dynamic page, the server processes the script to generate and send a unique page to the user. This allows for a more interactive and personalised user experience. For example, a dynamic web page might display different content based on the user's location, the time of day, or the user's interaction with the page.

Dynamic web pages are more complex to develop and require more server resources than static pages. However, they offer a more engaging user experience and are essential for web applications, e-commerce sites, social media sites, and any site that requires user interaction or real-time updates.

In summary, the main difference between static and dynamic web pages lies in how and when they are generated. Static pages are pre-coded and remain the same for every user, while dynamic pages are generated in real-time and can change in response to user interaction or changes in data.
