About This Topic

Web development is the work of building websites and web applications that run in a browser and communicate with servers over the internet. Beginner questions check the three front-end languages and their roles: HTML for structure, CSS for presentation and JavaScript for behaviour. You should be able to separate front-end, back-end and full-stack work, static from dynamic sites, and the client-server model from peer-to-peer. Expect items on URLs, domain names and DNS, what a browser engine does, browser developer tools for inspecting elements, the purpose of frameworks and version control with Git, and short definitions of terms such as the critical rendering path and CORS.

Below are 30 practice questions from a pool of 210 Introduction to Web Development MCQs, one of 17 topics in Web Development. Each shows the correct answer with an explanation; when you are ready, take a timed quiz to test recall under exam conditions.
