Broadcast
With reference to Ethernet, a broadcast is defined as a packet that will be sent to all hosts in the broadcast domain (the area between routers/switches).A broadcast is addressed to a MAC of FF:FF:FF:FF:FF:FF, (equivalent to 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.
It appears from my quick readings that we have:
* Ethernet broadcast * Limited broadcast * Directed broadcast
It may be worth expanding each of these into their own subsection, especially as we are dealing with multiple subnets in our network.

pdf appears to be a reasonable overview.I've made a couple of changes to your original, revert them if need be.
