In RAM, parity is a type of built-in error-checking system.
After the 8 bits in a byte receive data, even parity works by adding to total number of 1s. If the number is odd, the parity bit is set to 1; if the number is even, the parity bit is set to 0. When the data is read back, the total is added up again and compared to the first total. If the parity bit is 1, the data is error-free, but if the total is odd and the parity is 0, the chip recognizes a problem and gets rid of the data.
Odd parity works in the same fashion, just the other way around.

Who was t Sigmund Freud?
Sigmund Freud was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst. He is known for his theories on the unconscious mind, such as the Oedipus complex and the id, ego, and superego. Freud's work has had a lasting impact on psychology and popular culture.
Why is Sigmund Freud known for?

Which method of disk writing does RAID 5 uses?
parity
Is parity used for servers?
Parity is an error detection method used to ensure integrity of DATA in Transmission or Storage applications. Parity Methods are used in Computing Machines whether it is a Server, Workstation or a Laptop.
Why parity method can't detect double error?
The parity method detects errors by adding an extra bit to ensure that the total number of 1s in a binary string is even (or odd, depending on the scheme). If two bits are flipped, the parity remains unchanged, making it impossible for the parity check to recognize that an error occurred. Consequently, the method can only detect an odd number of bit errors, failing to identify double errors that result in an even parity. Thus, while it can catch single errors, it is ineffective against double errors.
What is a fault tolerance measure known as disk striping with parity?
RAID-5 provides data redundancy by using parity. Parity is a calculated value used to reconstruct data after a failure. While data is being written to a RAID-5 volume, parity is calculated by doing an exclusive OR (XOR) procedure on the data. The resulting parity is then written to the volume.
What is the difference between parity and non-parity memory?
Non-parity memory is memory without parity. Parity memory is memory with extra bits, sometimes one, sometimes more, that accompany the word. These extra parity bits are generated to a known value, typically to make the total number of bits on that word even or odd. When the word is retrieved, the parity bits are compared against what they should be. If they are different, then one or more of the bits in the original word or in the parity bits must have changed. This is an error condition that can be trapped. In a multiple parity bit system, the calculation of the bits allows not only for the detection of a changed bit, but also for the identification of which bit changed. This is known as ECC parity, or Error-Correcting-Code. Often, you can detect and correct any one bit error, and you can detect, but not correct, any two bit error. Since random bits changes are rare, those that do occur are usually one bit errors, making ECC parity valuable for high reliability systems such as servers.
What is a Paribit?
Paribit is a combination of two words; Parity and Bit. In early nineties computing, a check digit or Parity Bit was assigned to a sequence of bits that were to be transmitted over a network. The parity bit was used for security and transmission verification purposes. It either made the entire sequence of bits, even or odd, depending on the checking mechanism being used. Transmissions today use a method called packets and does not employ the check digit method.
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?

How explain the terms even parity and odd parity Is one method bettrer than the other?
"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.
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.
