## What is: "parity" ‒Definiciones and concepts -

### 1. Concept of parity in the Wikipedia Encyclopedia

Parity codes are used in telecommunications to detect, and in some cases correct, errors in transmission. For them is added in origin an extra bit called parity bit to the n bits that form the original character.
This parity bit is determined so that the total number of bits 1 to transmit torque (torque parity code) or odd (odd parity code).
Par parity code
The parity bit will be a 0 if the total number of 1 to transmit torque.
Odd parity code
The parity bit will be a 1 if the total number of 1 is odd.
Normally the parity bit is added to the left of the original character.

### 2. Definition of parity

In telecommunications, parity refers to the process of introducing an additional bit (known as parity bit) at the beginning of a data transmission, something that helps find and fix mistakes.
For the economy, the parity tend to be a value that allows you to compare one currency with another. It speaks of parity of purchasing power, on the other hand, to refer to the total of the products and services generated in a region according to the value of the currency of a nation that is taken as a reference point.
