lossless compression

lossless compression读音音标

lossless compression意思解释

释义

无损压缩；

英英释义

Lossless data compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data. By contrast, lossy data compression, permits reconstruction only of an approximation of the original data, though this usually allows for improved compression rates (and therefore smaller sized files).
