What is the destination used in an ethernet broadcast known as?

The destination used in an ethernet broadcast is known as the broadcast address. In Ethernet networking, when a frame is sent to the broadcast address, it is intended for all devices within the local network segment. The broadcast address is a specific address, typically represented as all binary 1’s in the host portion of the address (for IPv4, this is commonly 255.255.255.255 for a network).

Using the broadcast address allows a single packet to reach all devices on the same local area network (LAN) without needing to specify each device’s individual address. This is particularly useful for protocols that need to communicate the same message to multiple devices at once, such as ARP (Address Resolution Protocol) for discovering MAC addresses mapping to an IP address.

In contrast, the other options do not accurately describe the destination used for Ethernet broadcasts. An input address might suggest an address where data is sent but does not specifically refer to the mechanism of addressing all devices. The link address could relate to the MAC addressing scheme used in networking but does not imply a broadcast context. Similarly, the network address refers generally to an address denoting a specific network and is not synonymous with a broadcast address. Thus, the broadcast address stands out as the correct and specific
