Assume that we have a network with the following machines: 10.75.40.1 10.75.40.45 10.75.40.65 10.75.40.100 10.75.40.150 10.75.40.175 10.75.40.200 a) If these machines are connected via a hub and we transmit from one of these machines to the other, how many of these machines "see" the packets? (Give an exact number, and include the machine that initially sent the packet in your count, since it "sees" the packet too.)
