Which streaming technique allows users to view a file before it is fully downloaded?

• A. Progressive download
• B. Random access streaming
• C. Real-time streaming
• D. Continuous streaming

Answer: (C)

The correct technique that allows users to view a file before it is fully downloaded is progressive download. This method starts playing the media file while it continues to download, enabling users to begin viewing or listening before the entire file has been transferred. Progressive download is particularly beneficial for users with slower internet connections, as it provides a smoother experience by buffering just enough content to maintain playback without interruptions. In contrast to the other options, random access streaming provides the ability to skip to different parts of a file without needing to download it sequentially, which can be advantageous for specific applications. Real-time streaming typically refers to data being sent and received concurrently, such as live broadcasts, where latency is a significant concern. Continuous streaming implies a steady flow of data without interruption, but it generally requires that the content is available for immediate playback, which may not allow for accessing or viewing until more content has been buffered.
