nor gate
LowTechnical
Definition
Meaning
A digital logic gate that outputs true only when all its inputs are false.
In computing and electronics, a fundamental building block of digital circuits that implements logical NOR (NOT OR) operation.

Examples
By CEFR Level
- A NOR gate is a type of electronic switch.
- The symbol for a NOR gate looks like an OR gate with a small circle.
- You can build any logical function using only NOR gates, making them functionally complete.
- The output of a two-input NOR gate is high only when both inputs are low.
- In the implemented circuit, the cascaded NOR gates produced the desired parity check functionality.
- De Morgan's theorem allows us to express an AND operation using only NOR gates.
Learning
Memory Aids
Mnemonic
NOR = NOT OR. Remember: it says NO to all OR conditions.
Conceptual Metaphor
A strict bouncer who only lets you in if NOBODY is on the list (all inputs false).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'ни ворота' – it's not about physical gates.
- The 'gate' here means логический элемент, not калитка.
Common Mistakes
- Writing as 'norgate' (should be two words or hyphenated: NOR-gate).
- Confusing with 'OR gate' or 'NOT gate'.

Frequently Asked Questions
Yes, NOR gates are functionally complete. You can construct AND, OR, NOT, and any other logic gate using only NOR gates.
An OR gate outputs true if ANY input is true. A NOR gate outputs true only if NO inputs are true (it's the inverse of OR).
In digital circuits like processors, memory cells, arithmetic logic units (ALUs), and basic logic trainers for education.
The term 'gate' comes from the idea that it controls the flow of digital signals, like a gate that opens or closes based on logical conditions.
