Answer / deepak meshram
Publish/subscribe (or pub/sub) is an asynchronous messaging
paradigm where senders (publishers) of messages are not
programmed to send their messages to specific receivers
(subscribers). Rather, published messages are characterized
into classes, without knowledge of what (if any)
subscribers there may be. Subscribers express interest in
one or more classes, and only receive messages that are of
interest, without knowledge of what (if any) publishers
there are. This decoupling of publishers and subscribers
can allow for greater scalability and a more dynamic
network topology.
Pub/sub is a sibling of the Message Queue paradigm, and is
typically one part of a larger Message-Oriented Middleware
solution. Most messaging systems support in their API (e.g.
JMS) both the pub/sub and Message Queue models.

Answer / satyendra nath
publish and subscribe refers to 1 to n here we do have multicast and broad cast.
In TOPIC one message can be send to any number of subscribers who are interested on that particular message.
Multicast is in b/n publisher and known subscriber
Boardcast is in b/n publisher and many unknown subscribers
