Checking for errors in data transmission. A calculation is made on the data being sent and the results are sent along with it. The receiver then performs the same calculation and compares its results with those sent. If an error is detected the affected data can be deleted and retransmitted, the error can be corrected or concealed, or it can simply be reported.
The process of detecting erroneous digital information after data recovery in the receiver. Erroneous information usually results from transmission errors. Error detection exploits the properties of a code applied to the data in the transmitter. See also Error Correction.
A process used during file transfer to discover discrepancies between transmitted and received data. some file transfer programs only detect errors; others detect errors and then attempt to fix them in a process called error correction.
A set of techniques that can be used to detect errors in received data. Techniques that are applicable include parity checks involving parity bits, checksums or a Cyclic Redundancy Check.
A method that detects errors in received data by examining cyclic redundancy checks (CRC) or checksum.
Techniques used to identify errors in data transfers. See: check summation, cyclic redundancy check [CRC], parity check, longitudinal redundancy.
A technique for detecting when data is lost during transmission. This allows the software to recover lost data by notifying the transmitting computer that it needs to retransmit the data.
Checking for errors in data transmission. A calculation based on the data being sent; the results of the calculation are sent along with the data. The receiver then performs the same calculation and compares its results with those sent. If the receiver detects an error, it can be corrected, or it can simply be reported.
