Internet and web technologies are the technologies that are used to create and access the World Wide Web. This includes the Internet infrastructure, web browsers, web servers, and the languages and protocols that are used to create web pages, such as HTML, CSS, and JavaScript.
Board notes: AQA, Edexcel, and OCR all cover Internet and web technologies. Students should be able to explain how the Internet works and describe the key technologies that are used to create and access the web.
