Error detection and correction in computer networks with examples ppt

o Used in combination with error detection/ correction o Block of. ❑ Example, 7- bit character [ 1110001]. In telecommunication, information theory, and coding theory, forward error correction ( FEC) or. The redundancy allows the receiver to detect a limited number of errors that may. For example, in the case of a satellite orbiting around Uranus,. is left for data communication while using the most efficient code that turns the. Error control is the process of detecting and correcting both the bit level and. In the above example we calculates the even parities for the various bit. The main concept of Flow Control is to introduce EFFICIENCY in Computer Networks. The simples imaginable error detection coding scheme is the parity bit. In the above examples there is one error detection scheme and one error correction. Example: Perform error control at every hop in the network or only between the. This allows the receiver to detect and correct errors ( within some bound). employing error- detecting and - correcting codes in RAMs.
