A broadcast is the transmission of a single message to all hosts (i.e., computers or other devices) on the network simultaneously. Broadcasting is supported on most local area networks (LANs) and is also supported by some fax systems. It is also a useful feature in e-mail systems. Multicasting differs from broadcasting in that it sends the message just to a select list of recipients rather than to every host on the network. Unicasting is sending a message to a single host. A broadcast address is a special type of networking address that is used for broadcasting. A broadcast domain is a logical area in a network that is reachable by a broadcast. The word broadcast originally meant scattering seed or fertilizer over a broad area rather than placing it in rows.
