Error detection and correction mechanisms are essential for reliable data transmission from "summary" of Data Communications and Networking by Behrouz A. Forouzan
Error detection and correction mechanisms play a crucial role in ensuring the reliability of data transmission. When data is transmitted over a network, errors can occur due to various reasons such as noise, interference, or hardware malfunctions. Without error detection and correction mechanisms in place, these errors can lead to corrupted data being received at the destination. Error detection techniques help identify when errors have occurred during transmission. One common method is using checksums, which involve adding extra bits to the data being transmitted to create a sum that can be verified at the receiving end. If the checksum does not match the received data, i...
