What Is the Difference Between Unicast and Multicast?

Answer:

Unicast:

The term unicast is a transmission method it can send information from one station to another station. Unicast is one-to-one communication. It is used when private information is needed to send from one station to another station.

Examples:

File transfer and web surfing are examples of unicasts there is a need for a single service provider in unicast. If there is a need to send information from one station to multiple stations then send the multiple unicast packets, this is called multiple unicasting here all packets contain the address of the particular stations. Multiple unicasts use the maximum bandwidth of the network. In unicast the sender, the packets to one receiver while in multiple unicast senders send the three packets and each packet contains the specific address to the different receivers.

• It has only one sender and one recipient.
• Unicast is one-to-one communication.
• It uses more bandwidth than multicast.
• It is not used to stream media content.

Multicast:

In a computer network, multicast is a transmission method used to send information from one station to the interested stations. Multicast is one too many communications. It is a mixture of broadcast and unicast. In unicast it sends information to one station in broadcast sends information to all stations while in multicast sends the packets of information to the selected stations.

Example:

Multimedia delivery and forwarding emails are examples of multicast. In multicast, the sender creates a single packet to send to the group of interesting stations. In a large network, it’s very hard to use multicasting because the small network of the internet is enabled in multicast. UDP is used for transport protocol in multicast.

• One-to-many communication
• It is not used on a large network scale.
• Multicasting uses bandwidth efficiently.
• It has one transmitter and several receivers.
