Broadcast
With reference to Ethernet, a broadcast is defined as a packet that will be sent to all hosts on in the broadcast domain.A broadcast is addressed to a MAC of FF-FF-FF-FF-FF-FF, or a subnet mask of 255.255.255.255.
A broadcast domain is only able to be segregated by OSI layer 3 devices (routers), in effect if a host is on the same network/subnet it will receive any broadcast sent on that network. However, the boundary between layer 2 and 3 is blurred by VLAN Switches - which also separate broadcast domains.
Diagram 1: In this situation, server has sent a broadcast to the network. Each workstation receives a copy.
