Disk caching improves hard-disk performance, but it does not do so by compressing files. Instead, disk caching works by temporarily storing frequently accessed data in faster, volatile memory (RAM), which allows for quicker access than retrieving the data directly from the slower hard disk drive (HDD). When data is read from the disk, it is kept in the cache, so that subsequent requests for that data can be serviced more quickly.

Compression may reduce the amount of data that needs to be written or read from the disk, but it can also add overhead in terms of processing time since the data must be compressed and decompressed. Therefore, the statement that disk caching improves performance by compressing files is incorrect.

Final Answer

False. Disk caching improves performance by storing frequently accessed data in faster memory, not by compressing files.
