This subtopic delves into the foundational dichotomy of web development, exploring how client-side scripts execute in the user's browser to enhance interactivity, while server-side scripts run on the web server to handle core logic, data processing, and database interactions. Understanding these roles is crucial for developing secure, efficient, and dynamic websites, and underpins all modern web application architectures.

Key skills and knowledge for this topic

Clearly differentiate between code that runs in the browser and code that runs on the server.
Identify at least two examples of client-side technologies (e.g., JavaScript, HTML5 forms validation) and two of server-side technologies (e.g., PHP, ASP.NET).
Explain how the web server delivers static pages and invokes interpreters for dynamic content.
Award credit for linking the choice of technology to practical constraints like bandwidth, latency, and security.

Examiner Tips

Expert advice for maximising your marks

💡Always structure comparisons using a clear framework (e.g., where code runs, main purpose, security implications).
💡Use real-world analogies (like restaurant kitchen vs. table) to solidify understanding of the server-client relationship.
💡Practice tracing a request from URL entry to rendered page, explaining each step.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing JavaScript with Java or assuming all scripting is client-side.
Believing that client-side code is invisible to the user, thereby mishandling sensitive data.
Overlooking the stateless nature of HTTP and failing to explain session management.
