Computer viruses are referred to living viruses as they both have similar effects.
Explanation:
While living viruses invade cells and cause harmful effects on the body, computer viruses basically do the same thing. Computer viruses are a malicious code that inserts itself into a computer. It's designed to spread to one computer to another, just like a living virus.
Similarities:
- Spreads from one host to another.
- They both alter/harm the host.
- Both can replicate itself.
Differences:
- A computer virus is manmade, while living viruses aren't.
- A computer virus needs to be removed manually through an app or software while living viruses are almost curable medicine.
- A computer virus effects machines and software while living viruses only infect living organisms.
