What is one advantage of lossless compression?

1. Files can be compressed to a very small size

2. Files can be opened and recompressed repeatedly without data loss

3. Files are stripped of all unnecessary data

4. Files can be transported more quickly than a lossy file

The correct answer is: Files can be opened and recompressed repeatedly without data loss

One significant advantage of lossless compression is that files can be opened and recompressed repeatedly without any data loss. This type of compression reduces file size while preserving all the original data, allowing the files to maintain their integrity after being compressed. When a file is compressed using a lossless method, it can be restored to its exact original state without any degradation or missing information, making it ideal for applications where quality is critical, such as audio, video, and certain types of images. This is especially useful for professionals in fields like audiovisual production and graphic design, where maintaining the original fidelity of files is essential. In contrast, while some options may seem related to file management, they don't encapsulate the primary advantage of lossless compression in terms of data integrity. The first option suggests that files can be compressed to a very small size, which might be true, but lossless methods may not achieve as small a size as lossy algorithms. The third option discusses stripping unnecessary data, which is more characteristic of lossy compression rather than lossless. The last option regarding transport speed does not specifically address the core benefit of maintaining data integrity during repeated compression and decompression.
