How many rows in a 2-input NOR gate truth table produce output 1?
Explanation
Only one row (A=0 B=0) produces output 1 in a 2-input NOR gate. All other combinations produce output 0.
Reference: Computer Studies Textbook , Page 7
Hint
NOR is the complement of OR — OR has one row with output 0 so NOR has one row with output 1.
