Journaled File System (JFS)

A Journaled File System (JFS) is a way computers manage and organize data on storage devices to ensure reliability and integrity. It uses a special log, or journal, to keep track of changes before they are fully written to the storage. This process helps prevent data corruption if the system crashes or loses power during updates. By meticulously recording actions beforehand, JFS ensures that the file system remains consistent and recoverable, making it a valuable tool for maintaining data integrity in various computing environments.
