Which message delivery option is used when all devices need to receive the same message simultaneously?
- duplex
- broadcast
- unicast
- multicast
| Explanation & Hint:
When all devices need to receive the same message simultaneously, the message would be delivered as a broadcast. Unicast delivery occurs when one source host sends a message to one destination host. The sending of the same message from a host to a group of destination hosts is multicast delivery. Duplex communications refers to the ability of the medium to carry messages in both directions. |
