Networks might use error-correcting codes instead of error detection to ensure data integrity and reliability, especially in environments where retransmitting data is costly or impractical, such as in real-time communications. Error-correcting codes allow the receiver to identify and correct errors without needing a retransmission, thus enhancing throughput and reducing latency. This capability is particularly valuable in applications like satellite communications or streaming media, where maintaining a continuous flow of data is crucial.
1)Time taken to error correcting is less than doing detection and retransmission. Bandwidth use will be less. 2) In detection and retransmission if back messaging occurs the bandwidth will be more

Used for error detection
switches and your mama.!! lol haha
Error-Correcting Code or EEC
Error-correcting code for long burst errors is so complex that it is a inefficient means of 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.

cyclic error-correcting codes
is the set of standard rules for data representation, signaling, authentication and error detection required to send information over a communications channel
Systematic error detection is the process of identifying and correcting consistent errors or biases in data collection, measurement, or analysis. This helps ensure the reliability and accuracy of results by addressing any recurring issues that may affect the validity of the findings. Common techniques for detecting systematic errors include using control groups, calibrating instruments, and conducting multiple trials.
hii frnds it provides framing error control, flow control and link management, error detection and correction
