In computing, the File Alteration Monitor, also known as FAM and sgi_fam, provides a subsystem developed by Silicon Graphics for Unix-like operating systems. The FAM subsystem allows applications to watch certain files and be notified when they were modified. This greatly aids the applications, because before FAM existed, such applications would have to read the disk repeatedly to detect any changes: this resulted in high disk and CPU usage.
