How caching enhances file system performance?

Caching enhances file system performance by storing frequently accessed data in a faster storage medium, such as RAM, which reduces the time required to retrieve files. By keeping copies of popular files or data blocks readily available, the system minimizes disk I/O operations, which are typically slower. This leads to quicker access times and improved overall system responsiveness, particularly for repetitive tasks. Additionally, caching can reduce wear on physical storage devices by lowering the number of read/write operations.
