WebError-correcting codes are used in lower-layer communication such as cellular network, high-speed fiber-optic communication and Wi-Fi, [11] [12] as well as for reliable storage in media such as flash memory, hard disk and RAM. [13] Error-correcting codes are usually distinguished between convolutional codes and block codes : Webconvolutional code allows the correction of widely scattered errors but is not able to correct highly concentrated errors. The Reed-Solomon algorithm is often used in NAND flash memory interfaces. Reed-Solomon codes are often used to handle NAND flash bit-flipping phenomenon. The Reed-Solomon Algorithm is therefore widely used
