Exploring the World Wide Web (WWW)
Lesson details
Learning outcome
I can explain how the components of the World Wide Web (WWW) work together to display web pages.
Key learning points
- The World Wide Web (WWW) relies on web browsers, web servers and web pages to deliver information and services.
- Explain how the internet uses packets to efficiently and reliably transmit data across networks.
- The HTTP protocol is used govern how data is exchanged between web browsers and servers.
- The HTTPS protocol provides secure communication between web browsers and servers.
Keywords
Web server - a networked computer that stores and provides web pages and other data on request
HTTP - Hypertext Transfer Protocol, a set of rules that allows data such as web pages to be sent and received across the WWW
HTTPS - the Hypertext Transfer Protocol Secure is a set of rules that allows data to be encrypted and exchanged securely via the WWW
Packet - a segment of data, usually part of a larger message
Common misconception
Data packets from a complete message always follow the same route to their destination. They are then put back together in the order they are received.
Data packets are split and will be sent using the most efficient route at the time which often changes. Packets include data parts so they can be reassembled at the destination as long as the order of the packets is identified before being sent.
Teacher tip
Help pupils visualise the process of breaking down a large amount of data into smaller packets by having them cut up and reassemble a printed image. They need to understand that the order of the packets should be determined by using a sequence number to help with reordering upon delivery.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
