What is the primary benefit of using a file system that implements journaling?
It increases the maximum size of files that can be stored
It maintains a log of file system changes to help recover from crashes
It compresses files to save disk space
It encrypts files for added security
The correct answer is 'It maintains a log of file system changes to help recover from crashes'. Journaling ensures that even in the event of a system crash or power failure, the file system can be restored to a consistent state by consulting the log. This reduces the risk of data corruption and loss. The other options, although related to file systems, do not accurately describe the primary benefit of journaling.
