Question: 1 / 485

What is the main characteristic of multicast transmission?

A message is delivered to all network devices

A message is sent to a specific device only

A message is delivered to a group of hosts

Multicast transmission is specifically designed to send a single message to a group of hosts that are interested in receiving that message, rather than broadcasting it widely to all devices on the network or directing it to just one specific device. This is particularly efficient for applications where a message, such as a video stream or a software update, needs to reach multiple recipients without the need for replication of the transmission for each individual recipient.

The essence of multicast is the ability to efficiently utilize bandwidth by allowing a sender to transmit a message just once to a designated group. This optimizes network resources and reduces unnecessary traffic. Thus, the main characteristic of multicast transmission is that it effectively delivers messages to a select group of hosts that have expressed interest in receiving them, facilitating resource sharing and better management of network traffic.
