What type of transmission is directed to a single destination device?

Unicast transmission is a method where data is sent from one specific sender to one specific receiver. This means that the communication is directed to a single destination device within a network. Unicast is essential for one-to-one communication, such as when a user sends an email or initiates a direct connection to a server. Since the information is aimed solely at that one device, it ensures that only the intended recipient processes the data, optimizing network efficiency and reducing unnecessary load on other devices in the network.

In contrast, broadcast transmission sends data to all devices on a network segment, meaning every device receives the information, which is not suitable when communication is meant for a single destination. Multicast, on the other hand, targets a specific group of devices rather than just one, allowing for more efficient data sharing among multiple receivers when necessary. Lastly, anycast also directs messages to any one of a group of devices, but the intended recipient is selected based on routing measures rather than being specifically predefined. This emphasizes the unique role of unicast in enabling direct communication between two distinct devices.
