An embedded system is a system capable of operating on flash devices, typically.  This generally includes non-volatile, solid state storage.  Embedded Systems typically do not communicate directly with the user, but they may.  Essentially, the operating system is on non-magnetic, non-volatile, static storage memory, as opposed to a HDD.
