Unicast

Unicast is a method of communication in networking where data is sent from one sender to one specific receiver. Think of it like mailing a letter to a single person — the message travels directly from the sender to that one recipient. This is different from broadcasting (sending to everyone) or multicasting (sending to a group). Unicast ensures that the information reaches only the intended device, making it efficient for private or targeted communication, such as sending an email or streaming a video directly to your computer.
