Checksum is an error detection method used by the TCP/IP protocol suite to detect errors in a block of data. Like LRC, checksum works on the entire data block. However, instead of using parity (like in the case of LRC), checksum uses addition, making it more reliable. A checksum is an error detection code, calculated …
Longitudinal Redundancy Check (LRC) is an error detection technique used by the TCP/IP protocol suite to detect errors in a block of data. Unlike Vertical Redundancy Check (VRC), which operates on a column-wise basis, LRC checks for errors horizontally across the entire block of data. In Longitudnal Redundancy Check (LRC), also called 2-dimensional parity, a …
Vertical Redundancy Check (VRC) is a simple error detection technique used in by the TCP/IP protocol suite to identify errors caused by the flipping of a single bit during network transmission. It is also known as parity check. Vertical Redundancy Check (VRC) adds a one bit to the data that to be sent. This bit …
Error detection and correction are techniques used in data communication to ensure the integrity and reliability of transmitted data. Suppose A is sending some data to B via some transmission media. This data may be corrupted during transmission. This simple means that a 0 bit may change to 1 or a 1 bit may change …
