Some Unix systems run a kind of flush or update daemon, which calls the sync function on a regular basis. On some systems, the cron daemon does this, and on Linux it was handled by the pdflush daemon which was replaced by a new implementation and finally removed from the Linux kernel in 2012. [ 3 ]

[9] Classes include machines, networks and resources while types refer to the kind of object within a class, e.g., script or image resources.
