Final answer:
Duplicates and overlays in computer systems often lead to data corruption, which is a significant safety issue, affecting data integrity and reliability. They do not contribute to improved performance, enhanced security, or a better user experience.
Step-by-step explanation:
When dealing with computer systems and technology, the issue of data corruption can arise from duplicates and overlays within a system. These duplicates can lead to the overwriting of valid data or the mismanagement of storage space, both of which can result in corrupted data sets. This is a significant safety issue when considering the integrity and reliability of data. It does not lead to enhanced security, improved performance, or a better user experience; in fact, it often results in the opposite. Ensuring that data management protocols are in place to prevent these issues is crucial in maintaining system integrity.
