|
|
Data will be loss to certain extend

|
Detailed explanation-1: -Which statements about lossy compression are FALSE?-Lossy compression is reversible.
Detailed explanation-2: -Which of the following is true about lossy compression? Lossy compression can compress data down to significantly less bits than lossless compression can.
Detailed explanation-3: -Which of the following is true of lossy and lossless compression techniques? Both lossy and lossless compression techniques will result in some information being lost from the original file. Neither lossy nor lossless compression can actually reduce the number of bits needed to represent a file.
Detailed explanation-4: -Lossy data compression permanently discards some of the original data. It exploits the fact that human beings cannot detect subtle differences in sounds and colours. Key data is retained and less important data is discarded when lossy data compression takes place.
