What is NOR Calculator?

NOR Calculator computes the bitwise NOR (NOT OR) operation — the inverse of OR. A bit in the output is 1 only when both corresponding input bits are 0; all other combinations produce 0. Like NAND, NOR is functionally complete and widely used in hardware design.

How to Use NOR Calculator

1

Select input base.

2

Enter two numbers.

3

The NOR result appears in all bases.

Common Use Cases

  • Designing NOR-gate based circuits.
  • Computing inverted OR bit patterns.
  • Verifying complement logic in digital design.

Example Input and Output

12 NOR 10 (decimal).

A=12, B=10
A: 12 (1100₂)
B: 10 (1010₂)
NOR result
NOR: 4294967281 (11111111111111111111111111110001₂)

Frequently Asked Questions

What is the difference between NOR and NAND?

NOR is the inverse of OR (both bits must be 0 for output 1). NAND is the inverse of AND (both bits must be 1 for output 0). Both are universally complete logic operations.
