What Does Error Control (EC) Mean?
Error control is the technique of detecting and correcting blocks of data during communication. In other words, it checks the reliability of characters both at the bit level and packet level. If proper error control is in place, transmitted and received data is ensured to be identical, as in many cases communication channels can be highly unreliable.
Techopedia Explains Error Control (EC)
Data can be corrupted while in transmission. In order to retain reliable communication, errors must be detected and corrected. Several error control protocols are available and make use of error detection and retransmission of corrected frames. Some of the common techniques used in error control is acknowledgements, timeouts and negative acknowledgements. In a network, two types of errors occur: single-bit errors and burst errors. With a single-bit error, only one bit of data is altered; in a burst error, two or more bits could be altered.
