Virus or Worm? — TechKnowSurge

About this interactive

What you are doing: deciding, one description at a time, whether it is a virus or a worm. The one line that matters: both self-replicate, so speed and damage do not decide it — dependency does. A virus inserts its code into an existing file or program and does nothing until a person runs that file; it travels host to host inside the files people share. A worm carries its own code, needs no host to live in, and spreads across the network by itself, with no user action, often filling bandwidth as it multiplies. How to use it: ask whether it needs a host file and a human to run it. If yes, virus. If it spreads on its own as a standalone program, worm. A wrong answer resets your streak and shows the right bin.

What you'll learn

Tell a virus from a worm by the one line that separates them: a virus needs a host file and a user to run it, while a worm is a standalone program that spreads itself across the network
Explain that both self-replicate, so replication alone does not decide it — host dependency does
