The idea
ASCII assigns each keyboard character a unique binary code — seven bits covering 128 characters, extended to eight — standardized so machines of every brand can exchange text.
In practice
A capital letter and its lowercase twin carry different codes on every computer in the room.
Where people slip
Standardization across machines is the entire point.
