1 1.2.3 I/O Resources
1 -------------------
1 
1 'F'
1      Number of major, or I/O-requiring, page faults that occurred while
1      the process was running.  These are faults where the page has
1      actually migrated out of primary memory.
1 
1 'R'
1      Number of minor, or recoverable, page faults.  These are pages that
1      are not valid (so they fault) but which have not yet been claimed
1      by other virtual pages.  Thus the data in the page is still valid
1      but the system tables must be updated.
1 
1 'W'
1      Number of times the process was swapped out of main memory.
1 
1 'c'
1      Number of times the process was context-switched involuntarily
1      (because the time slice expired).
1 
1 'w'
1      Number of times that the program was context-switched voluntarily,
1      for instance while waiting for an I/O operation to complete.
1 
1 'I'
1      Number of file system inputs by the process.
1 
1 'O'
1      Number of file system outputs by the process.
1 
1 'r'
1      Number of socket messages received by the process.
1 
1 's'
1      Number of socket messages sent by the process.
1 
1 'k'
1      Number of signals delivered to the process.
