According to the OSI model which layer performs parity checking and error checking?
Data Link layer does the parity error checking Thanks, Samaresh
What is error checking?
Checks for errors.
What is parity checking used for?
Parity checking is used as a way to ensure data integrity and prevent errors, or detect them in the event they are occuring.
What error occurs if the number of bits is not an odd number for odd parity or an even parity?
parity error
What is meant by tree based parity check?
It is one of the type of parity checking methods. when the binary digits are formated as like the binary tree .Then calculate the parity from the root to each leaf node from left to right.
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.
Which bit is an extera bit attached to byte purposes of checking for accuracy?
It's called a parity bit.
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 has the author Alojz Neustadt written?

What has the author George Alessandria written?
George Alessandria has written: 'Violating purchasing power parity\\' -- subject(s): Purchasing power parity 'Inventories, lumpy trade, and large devaluations'
Which statements best describes redundancy checking?
Redundancy checking is a technique used to detect errors or errors in a data transmission. It involves adding extra bits to the data to create a checksum or parity. The receiver then checks for errors by recalculating the checksum or parity and comparing it to the received value. If they do not match, an error is detected.
What does the method known as parity do?
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.
