Describe the difference between lossy and lossless compressions, and tell when each might be used.
What will be an ideal response?
? Lossy compression is generally used with data that a human consumes, such as an image, a
segment of video, or an audio file. The key idea is that the compression only needs to preserve details to the level of human perception. That is, a change is acceptable if humans cannot
detect the change.
? Lossless compression preserves the original data without any change. Thus, lossless
compression can be used for documents or in any situation where data must be preserved
exactly.
