Paper 1
Revise: Binary Data ConversionThe reason comes from the computer’s hardware. Its processing circuits contain transistors, electronic components that act as tiny switches. For representing data, a switch has two states: on and off.
When explaining why computers use binary, link the hardware to the representation: transistors act as switches with two states, which can be represented by 0 and 1.
