(For error control, a checksum is added to the transmitted data. The verification method widely used in computer networks is (1). When the network uses the CRC check method, the valid generator polynomial of the check code is (2), and the check code generated according to the generator polynomial has (3) bits, and its error detection capability is (4), which is adopted after receiving the error. The error correction method is (5).)
