Mechanism

Follow the mechanism step by step and distinguish what causes the change from what is merely observed.

This extension applies that lens specifically to Computer Parts and Their Jobs.

Computer Parts and Their Jobs

A computer system receives input, processes and stores data, then produces output. Keyboard, touchscreen and microphone are inputs; screens and speakers are outputs.

Core checkpoint: Classify a part by the job it performs, not by its shape.
