A programmer is developing software for a social media platform. The programmer is planning to use compression when users send attachments to other users. Which of the following is a true statement about the use of compression?a. Lossy compression of an image file generally provides a greater reduction in transmission time than lossless compression does.b. Lossless compression of an image file will generally result in a file that is equal in size to the original filec. Lossless compression of picture files will generally save more space than lossy compression of picture files.d. Sound clips compressed with lossy compression for storage on the platform can be restored to their original quality when they are played.

An algorithm or formula is used by a programme to do compression to determine how much data should be compressed. For instance, an algorithm can represent a larger string of bits by breaking it down into a smaller string of 0s and 1s.

Lossless and lossy compression are the two options available. Because lossless compression algorithms don't compromise the integrity of the file, we can recreate the original data from the compressed version.

When a file is compressed using lossy methods, the data is deleted and not put back together again after decompression. In particular, data is irreversibly deleted, hence the name "irreversible compression" for this technique. Typically, this data loss is undetectable.
