Explain the difference between lossy and lossless data encoding.

• Lossy encoding sacrifices quality for smaller file sizes, while lossless encoding preserves all original data.

• Lossy encoding is always preferred for archiving data, while lossless encoding is not suitable for streaming.

• Lossy encoding is used for text files, while lossless encoding is for images.

• Lossy encoding retains all original data, while lossless encoding reduces file sizes.
