A broadcast network use to advertise the subnetmask of a particuler network

Agri Broadcast Network was created in 1972.

network layer

This is referred to as a broadcast storm.

10.56.176.0 is your network. 255.255.240.0 is your subnet mask. Valid broadcast addresses would be 10.56.176.255 (network broadcast) and 255.255.255.255 (general network broadcast). The general network broadcast would actually broadcast to every machine on the internet, but internet routers will block all traffic from it to prevent this. In effect if you use either 10.56.176.255 or 255.255.255.255, the result is broadcasting to all machines on your network.
