Broadcast Address
On any subnet, when the entire host portion of an IP address is all binary ones, it is a broadcast to all of the computers on that segment.
On subnet 192.168.1.0, the IP address 192.168.1.255 is a broadcast. On the larger subnetwork 190.55.0.0; the IP address 190.55.255.255 is a broadcast.
If all the digits in the host identifier are binary ones, the address is a broadcast. If all the digits in the host identifier are binary zeros, the address is a subnet number.
