Error Detection and Correction

Error control mechanism may involve Error detection and correction When data is sent from one device to another, the system cannot guarantee that the data received by the device is identical to the data sent by the other device. An error occurs when the message received at the receiver's end differs from the message transmitted. Many factors, including noise, cross-talk, and others, can cause data to be damaged during transmission. The upper layers are unaware of actual hardware data processing and work on a generalized…
