longitudinal redundancy การใช้

• Checksum schemes include parity bits, check digits, and longitudinal redundancy checks.
• The receiving terminal replies with CL ACK1, or CL ERR if the longitudinal redundancy check indicates a transmission error.
• In longitudinal redundancy checking and cyclic redundancy checking, block check characters are computed for, and added to, each message block transmitted.
• The adjective " transverse " is most often used when it is used in combination with additional error control coding, such as a longitudinal redundancy check.
• International standard "'ISO 1155 "'states that a longitudinal redundancy check for a sequence of bytes may be computed in software by the following algorithm:
• For USASCII, this is a one character longitudinal redundancy check ( LRC ); for Transcode and EBCDIC, the check sum is a two character cyclic redundancy check ( CRC ).
