Definition: Data can frequently be compressed by removing redundant sections (such as silences in music) or converting repeating sequences like ffffff into 6f, which reduces that text to 33% of its original size.
There are two types of compression:
- Lossless - where the compressed data can be uncompressed to return an identical copy of the original.
- Lossy - where some quality is lost to achieve greater compression but the loss is not noticeable.
