What is the difference between lossless and lossy compression techniques?
- Discards some data to achieve higher compression
- Only applicable to text data
- Preserves all original data during compression
- Reduces the size of data without any impact
Lossless compression preserves all original data during the compression process. It is commonly used for text and data where no loss of information is acceptable. In contrast, lossy compression sacrifices some data to achieve higher compression ratios, often used in multimedia applications where slight quality loss is acceptable.
