Casting in computer networks means transmitting data (stream of packets) over a network. Following are the different types of casting used in networking −Unicast transmissionBroadcast transmissionMulticast transmissionUnicast Transmission (One-to-One)In Unicast transmission, the data is transferred from a single sender (or a single source host) to a single receiver (or a single destination host).The network switches hear the MAC addresses of the devices on the networks to which they are connected. They can then forward packets only onto those networks containing devices with the connected MAC addresses. Unicast gradually becomes less efficient as more receivers need to see identical data.ExampleIn the ... Read More
