What is the Causes of error parity check 2 on a HP motherboard i865pe?
The cause of this error is a defective driver for the video adapter. To resolve this problem, a new driver for the video adapter must be installed.
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 is simple parity check related to the two dimensional parity check?
The single parity check uses one redundant bit for the whole data unit. In a two dimensional parity check, original data bits are organized in a table of rows and columns. The parity bit is then calculated for each column and each row.
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 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.
Define the purpose of PARITY?
A bit, added to every 8 bits, as a basic data integrity check. The value of this 9th. bit is either chosen so that the total number of 1's is even (even parity) or odd (odd parity).A bit, added to every 8 bits, as a basic data integrity check.

State the purpose of the parity track devices?
A parity bit, or check bit, is a bit that is added to ensure that the number of bits with the value one in a set of bits is even or odd. Parity bits are used as the simplest form of error detecting code.
How do you generate a parity check matrix?
In order to generate the parity check matrix you must first have the generator matrix and the codeword to check and see if it is correct. 1. Place your generator in row reduction form 2. Get the basis vectors 3. Put the vectors together to get the parity check matrix 4. Check it b multiplying the codewords by the parity = 0 For an example: 2*4 Generator Matrix [1 0 1 1 0 1 1 0] Rank = 2...therefore the number of columns is 2...Rank + X = # of columns of the Generator matrix v1+v3+v4 = 0 v2+v3 = 0 v1 = -r1-r2 v2 = -r1 v3 = r1 v4 = r2 Parity = [-1 -1 -1 0 1 0 0 1]
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.
How do you convert a parity check polynomial to a parity check matrix?
h0 + h1x + h2x2 ..... 1xk = 1 hk hk-1 ...... h0 0 0 0 0 1 hk hk-1 ...... h0 0 0 0 0 1 hk hk-1 ...... h0 0
Two communicating devices are using a singlebit even parity check for error detection. The transmitter sends the bye 10101010 and because of channel noise the receiver gets the byte 10011010. Wil?
The receiver won't detect the error, as a parity check bit only detects inversion of an odd number of bits.
How a serial parity generator and checker works?
We check the weather the number of bits at the input are odd or even and assign the parity bit to 1 or 0. And we do the same to check weather the output is the same as the input. Now as the probability of 2 bits going wrong and we may be confident enough just by checking one bit .
