What is lossless compression?
|
Detailed explanation-1: -With lossless compression, every bit of data originally in a file remains after it is uncompressed, and all the information is restored. Lossy compression reduces a file by permanently eliminating certain information, especially redundant information.
Detailed explanation-2: -There are two methods of compression – lossy and lossless. Lossy reduces file size by permanently removing some of the original data. Lossless reduces file size by removing unnecessary metadata.
Detailed explanation-3: -Lossless compression works by removing redundant data. These algorithms can usually reduce the number of bits required to store or transmit the data while guaranteeing that the original data can be perfectly reconstructed.
