Lossless Compression: This compression method reduces file size without any loss of data. It preserves all the original information by finding patterns in the data and representing them more efficiently.
Lossy Compression: Unlike lossless compression, this method sacrifices some quality or details in order to achieve higher levels of compression. It discards certain less important parts of the original file.
Data Redundancy: Refers to unnecessary repetition or duplication of data within a file, which can be eliminated by compression methods.
