Final answer:
The hosts are part of a broadcast domain, which includes all devices that receive broadcast messages on the same local network segment.
Step-by-step explanation:
The hosts described in the question are part of a broadcast domain.
In a local network, a broadcast domain refers to the group of devices that can receive broadcast frames originating from any device within the same network segment. When a host sends a broadcast message, it is delivered to all other hosts on the local network, and they process this message.
These hosts are connected through a switch, which helps in directing the traffic within the same broadcast domain without passing it to another network. The management of broadcast traffic is essential in network design as it can affect the performance and security of the network.
