Exact. In fact, for computers, it is even less important whether you use 220V or 110V plug. That's because all the components in your PC use direct current, with much lower voltage than 110V. You probably know the PSU (Power Supply Unit) in your PC, right? Well, what it does exactly is to take the 220V/110V electricity, rectify (make from alternate current to direct current), and then lower the voltage to values usable by the computer (+5V, -5V, +12V and +3.3V), which later may be converted to other voltages for each component (for example, the processor uses something around 1.5V).
So, no matter if the input is 110V or 220V, it will be converted either way to the same lower voltage, so the computer can really use it.
