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.
