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 else can I help you with?
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 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
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.
How is the value of a parity bit assigned?
Count the number of '1's in a binary value. If this number is odd, the parity bit is 1 - otherwise it's 0. RMS

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.
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?

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.
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

What does the math term parity mean?
Parity refers to whether an integer is odd or even.
