Question 1 of 10
What is the output of a 2-input OR gate if both inputs are 0?
In an OR gate, the output is 0 only when all inputs are 0.
Question 2 of 10
What is the Boolean expression for a 3-input OR gate?
The OR operation is represented by the '+' symbol in Boolean algebra.
Question 3 of 10
If the inputs of a 2-input OR gate are A=1 and B=0, what is the output Y?
The output of an OR gate is 1 if at least one input is 1.
Question 4 of 10
How many different input combinations are possible for a 3-input OR gate?
With 3 inputs, each having 2 possibilities (0 or 1), the total combinations are 2^3 = 8.
Question 5 of 10
When does a 2-input OR gate produce a low output?
An OR gate's output is low (0) only when all its inputs are low (0).
Question 6 of 10
What logic operation does an OR gate perform?
An OR gate performs the logical OR operation, returning true (1) if at least one input is true (1).
Question 7 of 10
Which of the following gate types is the inverse of an OR gate?
A NOR gate is the combination of a NOT gate and an OR gate, inverting the output of an OR gate.
Question 8 of 10
If input A = 1, B = 1, and C = 0, what is the output Y of a 3-input OR gate?
Since at least one input is high, the output of the OR gate is 1.
Question 9 of 10
What is the defining characteristic of an OR gate's operation?
The output is high if at least one input is high (1).
Question 10 of 10
The truth table for an OR gate defines the relationship between:
A truth table maps all possible input combinations to their corresponding output values.
