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 is the error detection technique that can detect errors with only one bit?
(a) simple parity check (b) two-dimensional parity check (c) crc (d) checksum
How does longitudinal parity works?
Longitudinal parity, sometime it is also called longitudinal redundancy check or horizontal parity, tries to solve the main weakness of simple parity.The first step of this parity scheme involves grouping individual character together in a block, as fig given below 1.1fig.Each character (also called a row) in the block has its own parity bit. In addition, after a certain number of character are sent, a row of parity bits, or a block character check, is also sent. Each parity bit in this last row is a parity check for all the bits in the Colum above it. If one bit is altered in the Row 1, the parity bit at the end of row 1 signals an error. If two bits in Row 1 are flipped, the Row 1 parity check will not signal error, but two Colum parity checks will signal errors. By this way how longitudinal parity is able to detect more errors than simple parity.
What is a parity track?
It's a track (a section of a magnetic disk, or a section of any given storage device that emulates a magnetic disk that uses the the LBA/CHS[Cylinder, Head, Sector]) that the computing device dedicates to store parity data (data to aid in error verification/correction for data that is stored on the disk).
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 are RAID 1 and RAID 5?
Raid 1 suppports the Mirroring if any one hard disk faild one will get the copy of the data and fault tolerent. after replacing the hard disk you have to re create the mirroring. Raid 5 supports stripped with parity the data will be deviced into blocks and stored in all the drives with the parity information. if any one or two hard disks faild the data will be available.
What happens when parity memory detects an error?
A parity error always causes the system to halt.
When parity memory detects errors what happens?
A parity error always causes the system to halt.
What can occur in older SIMMs and only happens when a module's parity information doesn't match information in memory?
Parity Error
What error occurs if the number of bits is not an odd number for odd parity or an even parity?
parity error
Can you mix and match ECC and non-parity modules?
No. When adding new memory, you need to match what is already in your system. Parity modules have an extra chip that detects if data was correctly read or written by the memory module, depending on the type of error. However, a parity module will not correct the erro
A problem with parity error indicates a problem with?
Parity error indicates bad memory. Parity checks compare the memory read with what was writen.
What is error checking?
Checks for errors.
What type of system error will a memory parity error create?
an NMI error
What causes parity error?
The main causes of parity error are magnetic or electrostatic conditions. This will result mainly into corruption of the computer memory chips.
An error message reads parity error what is the cause?
RAM problem.
According to the OSI model which layer performs parity checking and error checking?
Data Link layer does the parity error checking Thanks, Samaresh
What do you mean by single bit error correction?
A special system of multiple parity bits (e.g. Hamming parity) that allows not only error detection but limited error correction.Ordinary single bit parity can detect reliably single bit errors.Hamming parity can correct single bit errors and detect reliably double bit errors.
