What does bad checksum mean?

Checksum is a system by which a computer can verify the contents of a file against a known record, ensuring that the contents are correct and undamaged. A bad checksum error results when the file fails this check, meaning that some part of the data no longer corresponds to the original.

How is checksum used for error detection?

Error Detection in Computer Networks-.

Checksum-.

Step-01: If m bit checksum is used,the data unit to be transmitted is divided into segments of m bits.

Step-02: The data along with the checksum value is transmitted to the receiver.

Step-03: If m bit checksum is being used,the received data unit is divided into segments of m bits.

Checksum Example-.

What is checksum and how it works?

A checksum is the outcome of running an algorithm, called a cryptographic hash function, on a piece of data, usually a single file. Comparing the checksum that you generate from your version of the file, with the one provided by the source of the file, helps ensure that your copy of the file is genuine and error free.
