Question

How are the parts of a XOR are called?

A xor B = C

What is A and B called For Division it is:

A / B = C

A = divisor, B = dividend, C = quotient

For sums (and XOR is symmetric as the sum is) it is

A + B = C

summand for A and B, and sum for C

But I am missing a term for xor, how is it called and is there even one?

Sure you could go with operand or parameter or input or [...], but that is very generic, I would like to have a non-generic version.

Answer 1

As Soonts mentioned, the general name for thing operation thing would be an operand.

XOR being a logical or boolean operation, you could call it a logical / boolean operand. Often, they are also called input. Depending on usage, set or statement also works.
