Two-dimensional parity checks can be limited in their ability to detect errors, as they may fail to identify certain types of errors, such as two bits being flipped in the same row and column, which can result in undetected corrupt data. Additionally, the method adds extra overhead in terms of storage and processing, as it requires additional bits for both row and column parity. This can lead to increased complexity in both implementation and error correction. Finally, it does not provide error correction capabilities, only error detection, necessitating a more robust method for actual data recovery.

How is CRC superior to the two dimensional parity check?
Cyclic Redundancy Check (CRC) is superior to two-dimensional parity checks because it provides stronger error detection capabilities, allowing for the detection of multiple bit errors and burst errors, which two-dimensional parity checks may miss. CRC utilizes polynomial division to generate a checksum, ensuring that the data integrity can be verified more effectively. Additionally, CRC can be implemented with relatively low computational overhead, making it suitable for high-speed applications. In contrast, two-dimensional parity checks are limited to detecting only single-bit errors or even pairs of errors, making them less reliable for complex error patterns.

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.
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 the simple parity check related to the two-dimensional parity check?
The simple parity check adds a single parity bit to a data set to ensure that the total number of 1-bits is even or odd, which helps in detecting single-bit errors. The two-dimensional parity check expands on this concept by organizing the data into a grid, where each row and column has its own parity bit. This allows for the detection of errors in both rows and columns, enabling the identification of the specific location of a single-bit error. Thus, while both methods are designed for error detection, the two-dimensional parity check provides a more robust mechanism.

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.
Types of parity bits?

Why would you expect a CRC to detect more errors than a parity bit?
If there are two errors in a character, the parity may still be OK as two wrongs make one right, in this example. However such an error will not escape the CRC check as it is far more sophisticated and such a false positive is almost impossible to happen
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.
