A simple paritycheck bit which is normally added at the end of the word changing a 7bit ASCII character to a byte cannot detect even numbers of errors For example two four six or eight errors cannot be detected in this way A better solution is to organize the characters in a table and create row and column parities known as 2DParity check The bit in the row parity is sent with the byte the column parity is sent as an extra byte a Compare parity code and 2D parity code in terms of error detection capabilities and overhead Also describe a scenario where singleparity error detection would fail but 2D parity error detection would succeed b Represent how the following errors can be detected from the given figure i An error at R3 C3 ii Two errors at R3 C4 and R3 C6 iii Three errors at R2 C4 R2 C5 and R3 C4 iv Four errors at R1 C2 R1 C6 R3 C2 and R3 C6
