Lossy compression:
A. Discards some detail in order to reduce file size✓ 答案
B. Keeps every bit of the original identical
C. Applies only to plain text files
D. Always produces a file larger than the original
解說
Lossy methods such as JPEG for images or MP3 for audio throw away information the ear or eye is unlikely to notice, giving a much smaller file. The original cannot be rebuilt exactly.
