Error Detection Methods In Data Link Layer
many reasons such as noise, cross-talk etc., which may help data to get corrupted during transmission. The upper layers work on some generalized view of network architecture and are not aware of actual hardware data processing.Hence, the upper layers expect error-free transmission between the systems. Most of the applications would not function expectedly if they receive erroneous data. Applications such as voice and video may not be that affected and with some errors they may still function well. Data-link layer uses some error control mechanism to ensure that frames (data bit streams) are transmitted with certain level of accuracy. But to understand how errors is controlled, it is essential to know what types of errors may occur. Types of Errors There may be three types of errors: Single bit error In a frame, there is only one bit, anywhere though, which is corrupt. Multiple bits error Frame is received with more than one bits in corrupted state. Burst error Frame contains more than1 consecutive bits corrupted. Error control mechanism may involve two possible ways: Error detection Error correction Error Detection Errors in the received frames are detected by means of Parity Check and Cyclic Redundancy Check (CRC). In both cases, few extra bits are sent along with actual data to

remove this template message) In information theory and coding theory error detection and correction techniques with applications in computer science and telecommunication, error detection and correction or error control are error control in data link layer techniques that enable reliable delivery of digital data over unreliable communication channels. Many communication channels are subject to channel noise, and thus errors may be https://www.tutorialspoint.com/data_communication_computer_network/error_detection_and_correction.htm introduced during transmission from the source to a receiver. Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data in many cases.

Error correction is the detection of errors and reconstruction of the original, error-free data. History[edit] The modern development of error-correcting codes in 1947 is due to Richard W. Hamming.[1] A description of Hamming's code appeared in Claude Shannon's A Mathematical Theory of Communication[2] and was quickly generalized by Marcel J. E. Golay.[3] Introduction[edit] The general idea for achieving error detection and correction is to add some redu

ERRORCORRECTION & ERRORDETECTION Rutvi Shah 1 2. Data can be corrupted during transmission. For reliable communication, errors must be detected and corrected. Error detection and correction are implemented either at data link layer or the transport layer of the OSI model. Rutvi Shah 2 3. TYPES OF ERRORS Single bit error :- - Only one bit in the data unit has changed. Burst error :- - It means that two or more bits in the data unit has changed. Rutvi Shah 3 4. Single bit
