Broadcast

Broadcasting in networking means there is a single source that sends something to all other devices on the network, whether they want it or not. There are multiple types of broadcast traffic. For example, on layer two we can send an Ethernet broadcast if we set the destination MAC address to FF:FF:FF:FF:FF:FF. On layer three, we can send a broadcast by setting the destination to 255.255.255.255 or by using the broadcast address of the specific subnet.
