Digital communication systems rely on error detection and correction technokes to ensur data integrity during transmissionon. These methods identify and fix errors caused by noise, interference, or signol resolidation, improming reliability in variouses applications such such ahs internetdata transfeg, instantiote communicatión, and mobile networks.

Types of Error Detection Techniques

Error detection methodes add redundancy to transmitted data, lavilin the receir to identify errors. Common technolques include parity check, cyclic redundancy check (CRC), and checksum metods. Each varies in complexity and effectivenes, supertable for difect t system applements.

Error Correction Method

Error correction technologies note only detect errors but also correct them with out needin g retransmissionon. These include forward error correction (FEC) codes like Hamming codes, Reed- Solomon codes, and convolutionad codes. They are asseniad in environments where retranmissioni i instrucly or imposible ble.
