Broadcast: transmitting a packet that will be received by every device on the network
Unicast: the sending of information packets to a single destination
Multicast: delivery of information to a group of destinations simultaneously using the most efficient strategy to deliver the messages over each link of the network only once and only create copies when the links to the destinations split.
Unicast ---> A transmission to a single interface card.
Multicast ---> A transmission to a group of interface cards on the network.
Broadcast ---> A transmission to all interface cards on the network.
Unicast: the messages goes to a single computer.
Broadcast: the message goes to all the computers in a network.
Multicast: the message goes to a group of computers (basically, those that have registered themselves to participate in the multicast group).

Unicast transmission is a commonly used term in the technology world. Unicast transmission is essentially the sending of messages to a single network destination, which is identified by an address.

they are: 1.unicast 2.broadcast 3.multicast
The difference is in the IP range. The multicast IP range is 224.0.0.0 - 239.255.255.255

unicast
In computer networking, "multicast" refers to the delivery of data to a group of destination computers simultaneously in a single transmission from the source creating copies automatically in other network elements, such as routers, only when the topology of the network requires it. There are several multicast protocols. RFC 1458 - Requirements for Multicast Protocols attempts to standardize these protocols. Generally the possible routing schemes fall into one of a three main addressing methodologies, unicast addressing, broadcast or multicast addressing, and anycast addressing. Unicast addressing sends data from a single source to a single destination. In anycast addressing datagrams from a single sender are routed to the topologically nearest node in a group of potential receivers all identified by the same destination address. The data has multiple POSSIBLE recipients, but only one recipient winds up getting it. In broadcast and multicast addressing, a single sender sends a single message to multiple recipients simultaneously. Broadcast differs from multicast in that under broadcast, ALL computers on the network get the data while under multicast, only those computers targeted to receive it. For diagrams illustrating this, see the Wikipedia article in the related links.
