Computer Science / Unit 11 CS 0619 short lesson, about 20 seconds
Virus and Worm
Captions available
The idea
A virus propagates by arranging to have itself executed — infecting stored documents or code, typically with a user's help — while a worm replicates itself across a network without user intervention.
In practice
One spreads through a school's shared files and habits; the other walks the network alone.
Where people slip
The user's role is the dividing line.
