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.

dimensional analysis is very simple method for convert the one system of units into another system of units. And we can check the correctness of the equations. We can show the relations between physical phenomenal quantitatively.VALI
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
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.
