2. A malicious user learned how to substitute his address and
selected broadcast message, that forces each LAN computer to
answer by a message, that 1.6 times longer. How big amplifier
network is needed to shutup 10Mbit victim connection, if
a malicious user have only three dial-ups? Do you count this
actions as crime? And your police?
3. Make clear instructions, by following which even the most

3*. On Alpha Centaur planet three-fingered alphacentaurs lives.

program, just write alphacentaur multiplication table.
Luck!
