In potentiometer we use a slide resistance, so I think that is a wiper.

Please anyone give difference between them i.e. Rheostat, Wiper, Thermistor, Potentiometer?

Wiper is nothing but potentiometer which we can adjustable the resistance value. Where as rheostat is a variable resistance.

Rheostat have three terminals. One variable, 2 fixed terminals. Then how it can be rheostat?

Please any one tell me difference between rheostat and thermistor.

Wiper is a sliding contact in a potentiometer.

Potentiometer (IEEE): Adjustable resistor has 3 terminals.
Variable Resistor/Rheostat (IEEE): Adjustable resistor has 2 terminals.
Thermistor - Thermal resistor: Change resistance when temperature changes.
Photoresistor/Light dependent resistor (LDR): Changes resistance according to light.

Wiper is a sliding contact. Think of the meter bridge experiment where we use jockey, similarly wiper.
