Enter your Binary Data, choose an Parity Type (even or odd), and set the Parity Bit Position to get your Binary with Parity Bit — plus a breakdown of the Parity Bit Value, Original 1s Count, and Final 1s Count so you can see exactly how the error-detection bit was calculated.

A parity bit is an extra bit added to binary data to detect errors during transmission. It helps identify if any bits were corrupted or changed during data transfer by checking if the total number of 1s is even or odd.
Even parity adds a bit to make the total number of 1s even, while odd parity adds a bit to make the total number of 1s odd. The choice depends on the error detection system being used.
For 011101, count the 1s: there are four 1s. For even parity, add 0 (making it 0111010) to keep the total even. For odd parity, add 1 (making it 0111011) to make the total odd.
The parity bit can be appended (added to the right) or prepended (added to the left) of the binary sequence. The position depends on the communication protocol or system requirements being used.
Parity bits can only detect single-bit errors or odd numbers of errors. They cannot detect even numbers of errors (like 2, 4, 6 bit flips) and cannot correct any errors, only detect them.
Parity bits provide a simple and efficient method for error detection in digital communication and storage systems. They help ensure data integrity by identifying when corruption has occurred during transmission.
