Definitions. Error detection is the detection of errors caused by noise or other impairments during transmission from the transmitter to the receiver. Error correction is the detection of errors and reconstruction of the original, error-free data.

Which layer is responsible for error detection and correction?

Layer 2 of The OSI Model: Data Link Layer provides the functional and procedural means to transfer data between network entities and to detect and possibly correct errors that may occur in the physical layer.

How error detection and corrections is done?

7. How error detection and correction is done? Explanation: Error can be detected and corrected by adding additional information that is by adding redundancy bits. 8.
