Is the following statement true or false: A unicast flow is created by a transmitter alone.

The statement is false. In a unicast flow, the communication involves a one-to-one relationship between the transmitter and the receiver. This means that for a unicast flow to be created, it requires both the transmitter to send the data and the intended receiver to exist and be prepared to receive that data. Therefore, it is not accurate to say that a unicast flow is established solely by the action of the transmitter; both parties must be involved in the flow of communication for it to be established.

In a network configuration, the transmitter sends data specifically targeted to a single receiver’s address, and that receiver acknowledges and accepts this data flow. Without an active receiver ready to accept the unicast stream, the flow cannot be considered established. Hence, the correct understanding is that a unicast flow involves at least those two elements working together.
