Chris works as an IT consultant and was talking with his friends about how the WWW network might be easy to attack because of its type. What type is the WWW network and what property this network has that explains it?

Answer:

1. WWW is a Erdős-Rényi network and because of that is highly robust against random node removal but vulnerable to targeted attacks.
2. WWW is a Snobbish network and because of that is vulnerable against random node removal but robust to targeted attacks. Chris is wrong.
3. WWW is a scale-free network and because of that is highly robust against random node removal and to targeted attacks. Chris is wrong.
4. WWW is a scale-free network and because of that is highly robust against random node removal but vulnerable to targeted attacks.
5. None of the above.
