What type of logic is shown in the below diagram?

Explanation:
The diagram shows a gate in the OR family with a small inversion bubble at the output. An OR gate alone outputs high whenever any input is high. Adding the bubble flips that output, so the result is high only when both inputs are low. That combination—an OR gate with an inverted output—is the NOR gate. It outputs 1 only when both inputs are 0. This distinct symbol (OR shape with a bubble) differentiates it from NAND or plain OR or AND.
