Multicast
- (1) "Multicasting" refers to
sending
the same message or content to a select group whereas "broadcasting"
refers to
sending the same message or content to everyone connected to a network,
regardless of
who wants to see or hear it. An email related example of
multicasting is the e-mail "mailing list" (e-groups) where people sign
up to receive e-mail from everybody in the group (versus someone
sending the same email to everybody on the Internet.)
To receive a multicast, a client must have access to a multicast-enabled network. In contrast, an unicast is a one-to-one connection in which one client receives a distinct stream from a server.
