, a symmetry property of physical quantities or processes under spatial inversion - Parity (mathematics), indicates whether a number is even or odd
- Parity functionParity functionIn Boolean algebra, a parity function is a Boolean function whose value is 1 if the input vector has an odd number of ones.The parity function is notable for its role in theoretical investigation of circuit complexity of Boolean functions.-Definition:...
, a Boolean function whose value is 1 if the input vector has an odd number of ones - Parity flagParity flagIn computer processors the parity flag indicates if the number of set bits is odd or even in the binary representation of the result of the last operation. It is normally a single bit in a processor status register....
in computing, indicates if the number of set bits is odd or even in the binary representation of the result of the last operation - Parity bitParity bitA parity bit is a bit that is added to ensure that the number of bits with the value one in a set of bits is even or odd. Parity bits are used as the simplest form of error detecting code....
in computing, sets the parity of transmitted data for the purpose of error detection - Parity fileParity fileParity files are files that are created to accompany data files, and are used to preserve data integrity and assist in data recovery. They are useful when data files are transmitted or stored on less-than-perfect media such as newsgroup messages, satellite transmission, or optical disk...

The prices of the goods between the countries would only reflect the exchange rates...
, in economics, the exchange rate required to equalise the purchasing power of different currencies - Interest rate parityInterest rate parityInterest rate parity is a no-arbitrage condition representing an equilibrium state under which investors will be indifferent to interest rates available on bank deposits in two countries. Two assumptions central to interest rate parity are capital mobility and perfect substitutability of domestic...
, in finance, the notion that the differential in interest rates between two countries is equal to the differential between the forward exchange rate and the spot exchange rate - Put–call parityPut–call parityIn financial mathematics, put–call parity defines a relationship between the price of a European call option and European put option in a frictionless market —both with the identical strike price and expiry, and the underlying being a liquid asset. In the absence of liquidity, the existence of a...
