Difference between UniCast and Multicast

Unicast vs. Multicast

In computer networks, unicast refers to the transmission of information from a sender to a recipient. Thus, individual broadcasting concerns only two nodes of a network. The unique unicast receiver is identified by a unique address. In addition, multicasting refers to the transmission of information in a single transmission to a group of receivers. Multicasting is generally implemented as IP (Internet Protocol) multicasting.

What is unicast ??

With regard to computer networks, unicast refers to the transmission of information from a single sender to a single recipient. Unicast uses session-based IP delivery protocols, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). In unicast, each recipient or client connects to the server, consuming additional bandwidth. The client has a direct relationship with the server. For example, consider a situation in which you request the URL http://www.cnn.com from your computer. This request should only be received by the CNN server, otherwise the network will be filled with unwanted requests sent to other computers on the network. Unicast transmission is therefore essential for networks and is supported by Ethernet and IP networks. Http, smtp, telnet, ssh and pop3 are examples of unicast transmissions. Unicast is used when a private or unique resource is requested by a client. However, individual broadcasting is not suitable when transmitting information to a large number of customers, since the sender must establish separate connections with each recipient. This will consume computer resources in the sender and large bandwidth in the network.

What is multicast ??

As mentioned earlier, multicasting refers to the transmission of information to a group of receivers in a single transmission. In multicast, the source is required to transmit a data packet only once. Network nodes, such as routers, make the necessary copies of the transmitted data packet so that it can be received by multiple recipients. Intermediate routers send packets to recipients who have registered with to indicate their interest in receiving data from this particular sender. IP multicasting is one of the commonly used multicast implementations. In addition, the source does not need to know the addresses of the recipients it will multicast and there is no direct relationship between the sender and the recipients. Multicasting is not suitable for bulk data transfer and is generally not used widely on the Internet, since only small parts of the Internet are compatible with multicasting.

What is the difference between unicast and multicast ??

The main difference between unicast and multicast is the way they communicate with the receiver. In unicast, the information is transmitted to a single recipient by a single sender and the recipient maintains a direct relationship with it. In multicast, information is sent to multiple recipients in a single transmission, and there is no direct relationship between the senders and the recipients. Unicast is used when a private resource is requested by a client and is not suitable for transmitting information to a large number of clients because it consumes a large bandwidth of the network. Otherwise.
