Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

____ compression means that the file is identical, bit for bit, to the original uncompressed file.

A	Lossy
B	Lossless
C	Compressed
D	File

Explanation:

Detailed explanation-1: -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-2: -Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy.

Detailed explanation-3: -Compressed data files occupy less disk space than uncompressed data files. Files compressed with ZCOMPRESSED occupy the least disk space. Compressed files may take more or less time to open and save, depending on the file size and system configuration. Extra time is needed to de-compress and compress the files.
