Add up all the bits in a "word" - usually in 7 bits of an 8 but byte, and use the top bit in the byte to store the result. If there is an even number of bits set, the "parity bit" is 0, and if it is odd, the "parity bit" should be 1.
Electronic circuits can easily be made that generates this on say a COM port, that transmits one bit at a time and makes it possible to detect errors in the communication. It is also used in RAM memory - also to identify faulty memory chips. On disks they use more than 1 bit, and will here call it "ECC" - "Error Correction Circuitry". This is based on 3 bits that enables reconstructing the byte, not just detect an error.
Dense storage and fast transmission is always a trade-off with the correct stored data or data transmitted. Where the errors can be corrected without reducing capacity this is used.

Types of parity bits?
There are two types of parity bits.they are even and odd parity.
When parity detects an error what happens?
A parity error always causes the system to hault. On the screen, you see the error message parity error 1 (parity error on the motherboard) or parity error 2 (parity error on an expansion card)
What error occurs if the number of bits is not an odd number for odd parity or an even parity?
parity error
What is parity of authority and responsibility?
Parity of Authority and Responsibility?
what is meant by the terms odd parity even parity marking parity?
Odd parity and even parity are error detection schemes used in digital communication and computer memory. In odd parity, the number of bits set to '1' in a binary sequence is always odd, while in even parity, it is always even. Marking parity refers to a specific implementation of even parity where a binary '1' is added as a parity bit to ensure that the total number of '1's is even. These methods help identify errors in data transmission or storage by providing a simple means of checking integrity.
How are parity errors in memory detected?
Parity errors in memory are detected using a simple error-checking mechanism that involves an additional bit known as the parity bit. This bit is added to a group of bits (like a byte) to ensure that the total number of 1s is either even (even parity) or odd (odd parity). When data is read from memory, the system recalculates the parity and compares it to the stored parity bit; if there's a mismatch, a parity error is flagged, indicating that the data may be corrupted.
A problem with parity error indicates a problem with?
Parity error indicates bad memory. Parity checks compare the memory read with what was writen.
Which gate is used as parity checker?
It can be calculated via an XOR sum of the bits, yielding 0 for even parity and 1 for odd parity
What can occur in older SIMMs and only happens when a module's parity information doesn't match information in memory?
Parity Error
Parity in a sentence?
In high school football there is not always parity of skill levels among the teams. Parity means equal. It became evident that the skill level among the high school football team is not of parity.
How do you calculate parity?
Parity is calculated by determining whether the number of bits set to 1 in a binary representation is even or odd. For even parity, you add an extra bit to make the total number of 1s even, while for odd parity, you add a bit to ensure the total is odd. To calculate it, simply count the 1s in the binary string and use the appropriate rule based on the desired parity type. If the count is already even for even parity (or odd for odd parity), the parity bit is 0; otherwise, it is 1.
What is a difference between odd parity and even parity?
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
