When a process makes a file access, it is presented first to the cache of the process's workstation (``file traffic''). If not satisfied there, the request is passed either to the local disk, if the file is stored there (``disk traffic''), or to the server where the file is stored (``server traffic''). Servers also maintain caches in order to reduce their disk traffic. .)q .)z
