Vertical redundancy check computer networks error handling and error checking
add 0 at the end of data block if
- no of 1's are even and parity is given 'even'.
add 1 at the end of data block if
-no of 1's are odd and parity is given 'even'
for 'odd' parity given do opposite of above.
for eg.
data block is 1100101 parity ='even';
no of 1's = 4;
case 1 matched so, add 0 at the end and
output to be sent will be
11001010.
eg.
if data block =1010100 parity is even
then,
no of 1's = 3
odd no of 1's and even parity
add 1 at the end
output will be
10101001.
