Lossless and lossy are the two (2) universally known categories of
compression algorithms. Compare the two (2) categories of algorithms,
and determine the major advantages and disadvantages of each. Provide
one (1) example of a type of data for which each is best suited.
Thank you for the opportunity to help you with your question!
Lossless compression technique uses data compression algorithm that warranties the original (same) data to reconstructed from the data compressed. Thus, its useful when a user needs the compressed data to be the same after reconstruction.
data types that use lossless data compression
source codes and executable files
image file formats e.g. PNG
Lossy compression technique does not allow an identical data to be reconstructed after compression. Itr is useful in internet applications. For example, media streaming.
data types that use lossy data compression
Images eg MNG TIF
Lossy technique can produce a much smaller compressed data file compared to lossless technique
Lossless compression schemes are reversible so that the original
In practice, lossy data compression will also come to a point where compressing again does not work
Please let me know if you need any clarification. I'm always happy to answer your questions.
