?How does the JPEG compression algorithm work, and what are the trade-offs between compression ratio and image quality

JPEG works by dividing an image into blocks, applying discrete cosine transform (DCT) to each block, quantizing the coefficients, and then applying entropy coding. Higher compression ratios result in more loss of image quality due to increased quantization. The trade-off lies in finding the right balance between compression and acceptable image quality.

?What is the role of keyframes in MPEG video compression, and how do they impact video playback and streaming

Keyframes (I-frames) are full video frames that serve as reference points for subsequent frames (P-frames and B-frames) in a video sequence. They play a crucial role in video compression by reducing data redundancy. In streaming, they allow for random access and faster playback initiation.
