Error-Correcting Code or EEC
ECC- error-correcting code
The store-and-forward switching method is the one that provides the most thorough error checking. When this method is used, erroneous frames are discarded.
Synchronous
Checks for errors.
Vertical redundancy check (VRC)
Error checking, ie. checksum
Because in single stub method stub position has to be adjustible which create error......this is notin the case of double stub position method.........
Data Link layer does the parity error checking Thanks, Samaresh
In Excel 2007, on the Formulas ribbon, select the Error Checking option in the Formula Auditing section.

CRC is a method of checking one constant or value repeatedly to get the accurate answer(trial and error method), where as in the check sum it is not like the trial and error,since the answer got in CRC is more accurate when compared to check sum
A special system of multiple parity bits (e.g. Hamming parity) that allows not only error detection but limited error correction.Ordinary single bit parity can detect reliably single bit errors.Hamming parity can correct single bit errors and detect reliably double bit errors.
