What type of transmission method does unicast represent?

Unicast is defined as a one-to-one transmission method, meaning data is sent from one sender to a single specific receiver. This is a fundamental concept in networking, particularly in scenarios where a dedicated connection is established for the transmission. When a device sends data to one particular address on the network, it ensures that only the intended recipient receives that data.

In contrast to unicast, broadcast refers to sending data to all devices on a network segment, while multicast involves sending data to multiple specific devices that have shown interest in receiving that data, but not all devices on the network. Understanding unicast is crucial in scenarios where individual communication channels are required, as it allows for more controlled data distribution without overwhelming the network with unnecessary traffic.
