To provide additional robustness, the four samples immediately following the EAV packets ( but not the SAV packets ) contain a cyclic redundancy check field, and a line count indicator.
22.
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 ).
23.
It is preferred to its predecessor, superframe, because it includes a cyclic redundancy check ( CRC ) and 4000 bit / s channel capacity for a data link circuit capability and operating condition.
24.
In case you're wondering, a cyclic redundancy check is a type of error-checking mechanism that Windows uses to make sure the file you're moving / copying is intact.
25.
Data fidelity is ensured by a 32-bit cyclic redundancy check in each compressed data block using the Koopman polynomial ( 0xEB31D82E ), which has a Hamming distance of from 4 to 114 kbits.
26.
To start with, the SCC included a hardware implementation of the cyclic redundancy check ( CRC ), which allowed it to check, flag and reject improper data without the support of the host computer.
27.
The standards allow for a full cyclic redundancy check to be performed across all bits transmitted in each frame, to detect if the circuit is losing bits ( information ), but this is not always used.
28.
However, some are of particularly widespread use because of either their simplicity or their suitability for detecting certain kinds of errors ( e . g ., the cyclic redundancy check's performance in detecting burst errors ).
29.
Four types of Check Values were allowed, the original XMODEM checksum, a slightly modified version of the cyclic redundancy check ( CRC ) used in XMODEM-CRC, or the CCITT CRC-16 or CRC-32.
30.
It may consist of a cyclic redundancy check ( CRC ) of the frame, obtained as the remainder of the division ( modulo 2 ) by the generator polynomial multiplied by the content of the header excluding the HCS field.
