Which of the following is true about lossless data compression? a) it is only useful for files being sent over the internet. b) the compressed data can be restored back to its original state c) once a file is compressed, it cannot be read by anyone else but you d) there only exists one lossless compression algorithm. e) this algorithm is used regardless of what kind of data is being compressed.

b) The compressed data can be restored back to its original state.

Explanation:

What does lossless data compression mean?

Lossless data compression means that eventhough the data is compressed but that only compresses the size of a file however it retains the quality ; the quality is not lost during compression.

It is viable for both images and audio files

So what it does is to efficiently convert the file into a right size.

However the files will only be half size of the original file which means it still retains a larger size as compared to the lossy compression which will almost be tenth size of the original file .

The files can also be reconstructed back to the original file.
