Question

small explaination on parity check which clears the whole process in 5 lines at most

Answer 1

parity check is used to ensure whether the data sent is correctly received or not.There can be even parity or odd parity.If the no .of .ones in the data transmitted is even(even parity) then the no of ones in the received data also should be even(for an uncorrupted data) but if there is any corruption of data even parity may change to odd parity.Likethis,we can detect the corruptions using parity check.
