Computer Science / Unit 1 CS 0011 short lesson, about 20 seconds
Programs Are Stored Like Data
Captions available
The idea
A computer stores its programs in memory alongside the data those programs use — so improving a program means changing stored instructions, never rebuilding the machine.
In practice
An overnight phone update rewrites instructions; the hardware under them never moves.
Where people slip
This storage choice is what makes computers reprogrammable at all.
