(b) Can host C access the world wide web (WWW server) simultaneously while host B access the Internet through the router? Explain. (c) Can host A access the world wide web (WWW server) simultaneously while host B access the Internet through the router? Explain. (5 marks) (d) What is the maximum size of the hub's table (in the number of entries) in this configuration? (5 marks) (e) When host A sends an ARP query to learn the data link address of the router, can host C hear it? Explain.
