Hi Doug,

1.FILE is GLOBAL because it refers to the ability of the user to read/write
files on the server host filesystem (where the filesystem permissions
  1) user@localhost   OK, not recommended
  2) 'user@localhost'  WRONG
  3) 'user'@'localhost'  OK, BEST

single quotes prevent any problem in case of special characters in the host
