Now, we will go through performance of checksum error detection – Now, we have a clear about what a checksum is. Till now, we have seen different examples of checksum error detection technique. Thus, if the noise modifies the data in such a way that the vertically placed bits cancel each other and the calculated checksum is equal to the received checksum, such errors cannot be detected. ![]() The error is not detected in the received message. But, since the checksum is calculated to be same in both. Thus, there is a mismatch in the received code word. Then, we will first the divide the data into chunks of 2 digits. Suppose sender wants to send the data 713093 to receiver. Here, we will divide the data into different chunks of 2 digits. Then, use it to detect error during transfer.Ĭode word: Data bits appended with checksum. At first, we will see how to calculate checksum using decimal digits. Now, we will see about checksum error detection technique using decimal digits. Now, taking the compliment of the result(1111), we will get 0000. So, after receiving result, the result will be divided into chunks of 4 bit. Also, data were divided into 4 bits chunk. ![]() In previous example, the sender sent 011100110101.
