Lossless Compression:-
In lossless compression, the redundant information contained in the data is removed.
Due to removal of such information, there is no loss of information. That's why it is called lossless compression.
It is also known as data compaction.If the data have been losslessy compressed, the original data can be recovered exactly from the compressed data.
It is very important that the reconstruction is identical to the text original, as very small differences can result in statements with very difficult meanings.
Lossy Compression:-
In this type of compression, there is a loss of information in controlled manner.
This process is not completely reversible. But the advantage of this type is higher compression ratios than the lossless compression.
The lossless compression is used for the digital data.
