What's the difference between FMS and FMC? What's the difference between FMS (Flight management System), and FMC (Flight management computer)?

Can the flight management computer be thought of as what's manipulating the input information from the performance/navigation databases, and the FMS as being what actually provides the information?

I understand the information that's involved with the system, I'm just trying to define the difference based off an analogy of sorts.

The FMC is part of the FMS.


  The FMC is a computer system that uses a large data base to allow routes to be pre-programmed and fed into the system by means of a data loader.


The FMS encompasses:


  
  The Flight Management Computer (FMC)
  The Automatic Flight Control or Automatic Flight Guidance System (AFCS or AFGS)
  The Aircraft Navigation System
  An Electronic Flight Instrument System (EFIS) or equivalent electromechanical instrumentation.
