11. Lossy Compression

12. Decompression Reversion of compressed data Lossless data will be decompressed to its original form Lossy data will be decompressed to its near-original form

13. Color Synchronization Goal is to get colors to look the exact same on every monitor Prevalent in web pages Nearly impossible because of the different factors (monitor, web browser, surrounding light, OS)
