Computer Science for IGCSE & O level - Data Representation (Section 17 - No. 10)
Which statement describes the main trade-off when choosing between lossy and lossless compression techniques?
Lossy compression results in lower file sizes with no loss of data.
Lossless compression results in smaller file sizes, but may lose data.
Lossy compression offers higher compression ratios but may reduce quality.
Lossless compression techniques are always preferred over lossy techniques.
Vysvetlenie
Lossy compression provides better compression but with the risk of data loss and decreased quality, while lossless preserves data but compresses less effectively.
