These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- The TCP/IP model has four layers, each responsible for a different aspect of network communication.
- Common network protocols operate at specific layers and serve defined purposes in data transmission.
Keywords
Layers - a level in a model that describes how data is transmitted across a network
TCP/IP model - a conceptual four layer model and set of protocols for internet communications
Common misconception
Students may think protocols like HTTP or FTP operate at all layers, or that TCP and IP are the only protocols in the model.
Specific protocols perform unique functions at dedicated TCP/IP layers.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.
