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 is a parity bit added to a four bit word?
A computer word is NOT 4 bits.In computing terms the base unit is a "bit" which can be set to "0" or "1"Then a group of 4 bits is called a "nibble"2 nibbles or 8 bits is called a "bite"next comes a computer "word" which can be 16, 32 or 64 bits, depending on the width of the computer's registers.A parity bit is used as the simplest form of error detecting code, a parity bit, or check bit, is a bit ADDED to any string of binary code to ensure that the total number of 1-bits in the string is even or odd.
How do you type a check mark in word?
In the "menu" bar at the top of the screen, select "Insert"; then select "symbol"; under the "Font" box, select "Wingdings 2"; in the matrix select the "check mark"; then select "Select" at the bottom of the box and then select "Close" at the bottom of the box.

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]

How is an error corrected by using the Hamming code?
assume that u have received a code, you multiply it to parity check matrix and it results to syndrome, the syndrome identify you the error code from table look up which can be made by multiplying any probable error pattern in generator matrix.
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.
How do you know if you have simplified a polynomial correctly?
I suppose you mean factoring the polynomial. You can check by multiplying the factors - the result should be the original polynomial.

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.
