What is a characteristic of multicast messages?
They are sent to a select group of hosts.
They are sent to all hosts on a network.
They must be acknowledged.
They are sent to a single destination.
Which statement is correct about network protocols?
Network protocols define the type of hardware that is used and how it is mounted in racks.
They define how messages are exchanged between the source and the destination.
They all function in the network access layer of TCP/IP.
They are only required for exchange of messages between devices on remote networks.
