Study Notes
Compression Methods
- There are two types of compression methods: Lossy and Lossless.
Lossy Compression
- Data is lost permanently during compression.
- The original file cannot be reconstructed after compression.
- The purpose is to reduce the file size.
Lossless Compression
- Data is not lost during compression.
- Decompression results in an identical file.
- The purpose is to reduce the file size while preserving the original data.
Test your knowledge on compression methods with this quiz focusing on the differences between lossy and lossless techniques. Explore how data is treated in each method and understand how compression impacts file sizes.
