parity error
There are two types of parity bits.they are even and odd parity.
P (parity)is the count of '1's in the last 8 bits of any binary number expressed as even or odd. Logic 0 for odd parity; logic 1 for even parity.-if a number contains three binary one bits, it has odd parity-if a number contains no one bits, it has even parity
A bit, added to every 8 bits, as a basic data integrity check. The value of this 9th. bit is either chosen so that the total number of 1's is even (even parity) or odd (odd parity).A bit, added to every 8 bits, as a basic data integrity check.

It can be calculated via an XOR sum of the bits, yielding 0 for even parity and 1 for odd parity
A parity bit, or check 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.
That's called a "parity violation", which indicates a bit error in the byte. That's the whole purpose of parity ... detecting bit errors, although in order to do it, you have to significantly increase the data load by adding an extra bit to every 7 or 8 bits in the end-user's business traffic.
in even parity number of 1s is even called even parityand or number of 1s is odd called odd parity anil kuntal anil kuntal you suck
it is called even / odd parity check
"Parity" refers to the number of 1s in a given binary number. Odd parity means there are an odd number of 1s and even parity means that there are an even number of 1s. Parity bits are often used as a crude means of error detection as digital data is transmitted and received. For example, 0b11010100 has 4 1s in it, therefore, it has even parity. Two devices exchanging data must be set to the same parity. If both are set (strapped) for odd parity, for example, then the sending device must ensure that the number of bits in each word has an odd number of 1s. Likewise, the receiving device must be set to ensure it only receives words with an odd number of 1s. An odd parity bit is defined as a bit in the word which can be set to ensure odd parity. If the word already has an odd number of 1s, then the parity bit is not set. If the word otherwise has an even number of 1s, the parity bit is set to ensure an odd number of 1s. The same is true for even parity settings. One way is not necessarily better than the other in theory but, in practice, should observe the convention for the system in question. Many (if not most) devices provide a connector pin that can be strapped to define either even or odd parity.
Priority: Counting number of ones (1s) in the unit of data, since 0 is zero.Example: a unit of data: 1001 (=0x09) where number of 1s is 2 making even parity.So, the parity bit - the most significant bit will be '0' - "even" which makes the byte 0000-1001 or 0x09.Add 1, makes 10 - or xxxx-1010 still 2 bits set, making also even parity 0x0a.Add 2, makes 11 - or 1000-1011 - 0x8bYou can make a simple transistor as a "gate" we call XOR. If one OR the other pin is raised, then raise pin out. If none or both are set, pin out is set low. The difference between OR and XOR is the result of both.But use the "overflow" 4th pin of an OR "gate", and use this as input to the next bit and you "ADD" binary.
The parity rules are: Odd + Odd = Even Even + Even = Even Odd + Even = Odd Even + Odd = Odd So the parity where one number is even is that of the other number. This means that you can go through a list of numbers and ignore all the even numbers. Every PAIR of odd numbers has even parity and by the previous paragraph, even parity can be ignored. So you can pair off odd numbers and ignore them.
