Backward error correction is a technique used in data communication to improve the reliability of transmitted messages. In this method, the receiver checks for errors in the received data and, if any discrepancies are found, it requests the sender to retransmit the erroneous data. This approach allows for accurate recovery of the original message while minimizing the need for continuous error checking during transmission. By focusing on correcting errors after they occur, backward error correction enhances the overall efficiency of data communication systems.

What is the communication error correction?
Communication error correction refers to techniques used to detect and correct errors that occur during data transmission. These methods ensure that the information received is accurate and reliable, despite potential disturbances like noise or interference. Common error correction techniques include Forward Error Correction (FEC), where redundant data is added, and Automatic Repeat reQuest (ARQ), which requests retransmission of corrupted data. By employing these strategies, systems can maintain data integrity and improve overall communication reliability.

What is the difference between Error detection and error correction?
In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.
What is zero correction?
the correction which is made to get correct measurement after zero error
What is the purpose of a channel encoder and decoder in modern communication systems?
channel encoder inserts additional information to the transmitted bit stream to facilitate error detection and correction at the receiver. channel decoder is quite opposite to the channel encoder which transmits desired data after the error detection and correction .
Why does CD player register E23 on Pontiac sunfire?
E23 Communication Error: There is a vehicle/radio communication problem or an inter radio communication problem, Correction: Disconnect battery voltage to the radio and then reconnect after a few minutes.
What is the difference between error and correction?
Error refers to a mistake or deviation from accuracy, often resulting in incorrect information or outcomes. Correction, on the other hand, involves identifying and rectifying that error to align with the correct information or standards. Essentially, error highlights a problem, while correction is the process of addressing and resolving that problem. In summary, error indicates what is wrong, and correction provides a solution to fix it.
How do you calculate c correction in traverse?
To calculate the c correction in a traverse, you first determine the error of closure by comparing the computed coordinates of the traverse's starting and ending points. The c correction is then calculated by dividing the total error in the traverse by the total distance or the number of sides of the traverse, depending on the method used. This correction is then applied uniformly to each traverse leg to adjust the measured angles or distances, ensuring that the traverse closes accurately.
What is the simplest form of error correction?

What is the error correction mechanism?
Error correction mechanisms are techniques used in computer systems to detect and correct errors that may occur during data transmission or storage. These mechanisms typically involve adding redundant bits to the data to enable error detection and correction. Common error correction techniques include parity checks, checksums, and cyclic redundancy checks (CRC).
Why is error-correction code limited mostly to correcting errors one to three bits in length?
Error-correcting code for long burst errors is so complex that it is a inefficient means of error correction...
