Data compression redirect
from Lossy
audio compression,
representation Compression can be either
lossy or losslesS
Lossy compress files by
removing some of the file to make it smaller
i.e JPEG
Lossless compression
reduces bits by identifying
and eliminating
statistical
redundancy.Lossless compression are one where by original file before and after
remains completely unchanged.ie Tiff
Lossy: Is generally more effective
but when
opening file it loses some data. This is most
noticeable in compressed pictures
Lossless= Is the most common method of
compression and loses none of the data
