Learners are likely to be familiar with the NOT, AND, and OR logical operators from programming (and especially the Year 7 programming units). Through practice, learners can master the use of logical expressions in software, but it is a different story altogether to uncover the connection between logic and computing hardware.

This is the deeper goal of the lesson: to bridge the gap between logic and circuits, and to make explicit the direct link between them. 

This is the last step in the learners’ journey through the hierarchy of a computing system, from programs, to the hardware responsible for executing the programs, and now, to the fundamental components that comprise this hardware. 

This lesson is the fourth in a six session teaching unit provided by the National Centre for Computing Education.
