What technique can be used to compress both video and audio data?

1. JPEG

2. MPEG

3. MP3

4. AVI

The correct answer is: MPEG

MPEG, which stands for Moving Picture Experts Group, is a widely used standard for compressing both video and audio data. This technique enables significant reductions in file size while maintaining acceptable quality levels, making it particularly useful for streaming and storage. MPEG utilizes various compression methods that allow it to efficiently encode video and audio together, ensuring synchronization and optimizing performance across different platforms and devices. JPEG, while effective for compressing still images, does not handle audio or video data; therefore, it is not suitable for this purpose. MP3 is specifically designed for audio compression and cannot compress video data. AVI is a multimedia container format that can hold various types of video and audio codecs but does not inherently compress them itself; it relies on other encoding standards for compression. Therefore, MPEG is the best choice for compressing both video and audio data in an integrated manner.
