Detailed explanation-1: -Data compression can dramatically decrease the amount of storage a file takes up. For example, in a 2:1 compression ratio, a 20 megabyte (MB) file takes up 10 MB of space. As a result of compression, administrators spend less money and less time on storage.

Detailed explanation-2: -Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size. Fundamentally, it involves re-encoding information using fewer bits than the original representation.

Detailed explanation-3: -A) To compress something by pressing it very hardly (B) To minimize the time taken for a file to be downloaded (C) To reduce the size of data to save space (D) To convert one file to another Answer Correct option is C.

Detailed explanation-4: -Lossy compression reduces an image file size by permanently removing less critical information, particularly redundant data. Lossy compression can significantly reduce file size, but it can also reduce image quality to the point of distortion, especially if the image is overly compressed.
