This is a voltage follower or buffer amplifier circuit, where the output is simply equal to the input. The advantage of this circuit is that the op-amp can provide current and power gain; the op-amp draws almost no current from the input. It provides a low output impedance to any circuit using the follower's output, which means the output will not sag under load. In this case the load is a 1 kΩ resistor; the op-amp provides all the current needed to drive the load without requiring any current from the input.
