Question
What logical operation does an OR gate perform?
Answer Options
- A) It produces a 1 at its output if any input is 1
- B) It produces a 0 at its output if all inputs are 1
- C) It produces a 0 at its output if some but not all inputs are 1
- D) It produces a 1 at its output if all inputs are 0
Correct Answer: A
Explanation
The OR gate is a fundamental Boolean logic element. It is used to perform the logic of ‘either/or’—if either input condition is true, the output condition is true. It is a critical component in digital decision-making circuits.
The logical operation of an OR gate is that it produces a 1 at its output if any input is 1. The only condition under which the output will be a ‘0’ is if all inputs are ‘0’. This type of logic is used when multiple conditions can trigger a single result, such as an alarm or a flag in a digital system.
