Deep Dive: Virus vs Worm - The Critical Difference
Why the Distinction Matters
Understanding the difference between viruses and worms is crucial for GCSE exams:
VIRUS:
- Host dependency: MUST attach to a legitimate file or program
- User action required: Only spreads when user runs/opens the infected file
- Spread mechanism: User shares infected files via email, USB, downloads
- Analogy: Like biological viruses - need a host cell to survive and replicate
WORM:
- Standalone: Independent program - doesn't need a host file
- Self-replicating: Spreads automatically without user intervention
- Spread mechanism: Exploits network vulnerabilities to copy itself to other systems
- Analogy: Like an organism that crawls/wriggles between systems independently
