Thermostat is a mechanical device that reacts to heat. As heat is applied the thermostat contracts and allows water to flow through the system. A thermistor is a thermal resistance sensor that also reacts to heat. There are two kinds, one is a negative coefficient and is a positive coefficient. As heat increases it changes the resistance value of the thermistor. That resistance value is transmitted to the computer and/or temperature gauge. Through computation the computer can can tell what temperature the engine is at to make decisions on how it should be run.
