Unicast, Multicast and Broadcast what does it mean ?

UNICAST= point to point comunication, one source one destination

Multicast= Group comunication (static or dynamic group), one to All Group defined. others which is not in group can't view a packets.

Braodcast= one To All, one source All destination,  for example television.

1) Unicasting means the communication between one host to specified one

2) Multicasting means the communication between one to some specified hosts

3) Broadcasting means the communication between one to all hosts

unicast =1 to1

multicast =1 to many

broadcast =1 to every

Hi,

In IP v4 the data can be sent from one host to other hosts in the following types:

1. Unicast: data sent from one host to one host in a subnet

2. Multicats: data sent from one to many hosts(not all) in a subnet

3. Broadcast: data sent from one host to all hosts in a subnet

In IP v6 the data can be sent from one host to other hosts in the following types:

1. Unicast: data sent from one host to one host in a subnet

2. Multicats: data sent from one to many hosts(not all) in a subnet

3. Anycast: data sent from one host to many hosts (not all and the nearest hosts) in a subnet

HTH

Best Regards,

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.

Unicasting is one to one communication

Multicasting is one to many communication

Broadcasting is one to all communication and there is no security

Unicast : Data send to a specific computer using MAC address or Ip address

Multicast : Data send to many computer using MAC address or Ip address from an network

Broadcast : Data send to all computer from a network
