Simulator: A software program impersonating a Hardware. Thus SIMULATING the scenarios faced in the original hardware.

Emulator: A Hardware (with or without software) impersonating another Hardware. Thus ELIMINATING the need for the original.

In my opinion, I think, Simulator is the machine which the function is same as Remote Tools that is to manage, views, or upgrading the system or the performance(s).
Emulator is a machine that shows the weaknesses, power, file systems, etc. and it can use to execute, ReWrite permission(s), mount, etc. of one whole full systems.

Emulator - It could replicate the entire system, Although we could use as another as similar system preferable.

Both are related to Tools. But Emulators are hardware tools which are copy of actual hardware. some emulators are on chip which will come along with hardware (Micro controller).
Simulators are software tools which will just check the functionality and does not give timing details as that of emulators
