What technology allows for the real-time delivery of audio and video data?

The technology that allows for the real-time delivery of audio and video data is streaming services. Streaming refers to a continuous flow of multimedia content delivered over the internet, enabling users to access content as it is being transmitted without the need to download the entire file first. This technology is essential for various applications, including watching videos, listening to music, and live broadcasting events.

While video conferencing can facilitate real-time communication via audio and video, it is typically used for interactive meetings rather than for delivering content to a broader audience. Podcasting focuses on pre-recorded audio content distributed for later consumption. Webcasting is similar to streaming but usually refers to a unidirectional transmission of media over the internet and may not always offer real-time interaction or content delivery. Hence, streaming services encapsulate the essence of real-time media delivery effectively.
