Explanation
Unicast is a type of data transmission where a message is sent from one sender to one receiver, each identified by a network address. Unicast is a one-to-one communication, as opposed to broadcast and multicast, which are one-to-many communications. Unicast is typically used for real-time data streams, such as video, audio, or online presentations, that are shared with a single user over the Internet. Unicast can also be used for email, file transfer, and other applications that require a specific recipient.
