Bringing the TCP/IP model to life and why we must teach it

Duncan Maidens, Raspberry Pi Foundation

Description

Computer Networking still remains one of the 'difficult to teach' topics of the National Curriculum and is universally poorly understood. It is often presented as a series of disjointed facts linked to a model which are just definitions to memorise.

However the model provides the scaffolding to understanding networks and allow us to build up from the electrical signals that travel across the media, through two layers of addressing to the protocols needed by the applications we all use.

This session will use packet tracer to simulate data flow and illustrate the relationship between the TCP/IP model and the structure of the data in the frames, packets and segments. All the resources will be made available.

Relevant Key Stages: KS3, KS4
