7.	□	The MAC address, which is made up of two equal parts, is 6 bytes long.
8.	□	Multicast is a transmission from one node addressed to all other nodes on the network.
9.	□	In a bus network, information sent from a node travels along the backbone until it reaches its destination.
10.	□	In a star network, a hub performs all types of filtering and routing of traffic.
