Q
What is the maximum number of errors that can be detected using two-dimensional parity check code?
AA. 4
BB. 5
CC. 3
DD. 2
Correct Answer:
C. C. 3
Explanation:
Two-dimensional parity check was introduced to overcome the problem in simple parity check code that it is able to find only odd numbers of errors. Two-dimensional parity arranges the code into columns and rows and add parity bits in each column and row to find errors up to 3.
