It is - these days - typically the last (typically non-usable) address within a subnet after applying a mask to it. As stated below, if you had a 10.10.10.0/24 subnet/mask, then the following would be true: 10.10.10.0 = network (non-usable) 10.10.10.255 = network broadcast (usually non-usable) 10.10.10.1 - 254 = usable addresses within the subnet There is another type of broadcast, often called "all-nets" broadcast and back in the day, it could cause some securtiy issues, and that is the 255.255.255.255 address (a broadcast to all networks). Hope some of this helps. Broadcasting is an interesting little beast. It is - these days - typically the last (typically non-usable) address within a subnet after applying a mask to it.
