LAN data transmission fall into three classifications:
unicast, multicast, and broadcast.
In each type of transmission, a single packet is sent
to one or more nodes.
In a Unicast Transmission, a single packet is sent from the source to a destination
on a network. First, the source node addresses the packet by using the address
of the destination node. The package is then sent onto the network, and
finally, the network passes the packet to its destination.
A Multicast Transmission consists of a single data packet that is copies and
sent to a specific subset of nodes on the network. First, the source node
addresses the packet by using a multicast address. The packet is then sent into
the network, which makes copies of the packet and sends a copy to each node
that is part of the multicast address.
A Broadcast Transmission consists of a single data packet that is copied and
sent to all modes on the network. In these types of transmission, the source
node addresses the packet by using the makes copies of the packet and sends a
copy to every node on the network.
