Final answer:
A streaming protocol transfers data in and out as a stream of bytes, with no block structure. Examples include RTSP and HTTP.
Step-by-step explanation:
A **streaming** protocol transfers data in and out as a stream of bytes, with no block structure. One example of a streaming protocol is the **Real-Time Streaming Protocol (RTSP)**, which is used for controlling the delivery of data with real-time properties, such as audio and video streaming.
Another example is the **Hypertext Transfer Protocol (HTTP)**, which is commonly used for streaming media over the internet. With HTTP streaming, the data is divided into small chunks and sent as a continuous stream.
In contrast, a **block protocol** transfers data in discrete blocks of fixed sizes, such as the Transmission Control Protocol (TCP), which is commonly used for reliable data transmission over the internet.
