4. VRC

5. Vertical Redundancy Check Vertical redundancy check (VRC) is an error-checking method. The other name for VRC is Parity Check.  Parity bits are a simple form of error detecting code . Parity Bit (PB) Even parity Odd Parity In this method, a redundant bit also called parity bit   

6. It can detect single bit error. It can detect burst error only if the number of error is odd. Performance of VRC

7. Sender 11100001 Transmission Error 10100001 Receiver Rejects this Data Sender 11100001 Transmission Error 10100101 Receiver Accepted this Data Conclusion – 1 PB can only detect an odd number of errors

8. The purpose of a parity bit is to provide a simple way to check for errors Simplest type of error detection. It provides high efficiency to detect errors. WHY WE USE VERTICAL REDUNDACY CHECK METHOD ? Only 1 parity bit is flipped it means the parity is in error.

9. Limitations of vertical redundancy check There are two conditions which can cause a parity checking mechanism to fail to detect errors properly. Parity Bit Corruption  Data Bit Corruption  Combination  Transmission Error 10100101 Receiver Accepted this Data Sender 11100001
