3. Mathematics of cyclic redundancy checks - Wikipedia

   en.wikipedia.org/wiki/Mathematics_of_cyclic...

   All the well-known CRC generator polynomials of degree have two common hexadecimal representations. In both cases, the coefficient of x n {\displaystyle x^{n}} is omitted and understood to be 1. The msbit-first representation is a hexadecimal number with n {\displaystyle n} bits, the least significant bit of which is always 1.

4. Error detection and correction - Wikipedia

   en.wikipedia.org/wiki/Error_detection_and_correction

   A CRC has properties that make it well suited for detecting burst errors. CRCs are particularly easy to implement in hardware and are therefore commonly used in computer networks and storage devices such as hard disk drives. The parity bit can be seen as a special-case 1-bit CRC.

6. Error correction code - Wikipedia

   en.wikipedia.org/wiki/Error_correction_code

   Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.

7. Computer network engineering - Wikipedia

   en.wikipedia.org/wiki/Computer_network_engineering

   Computer network engineering is a technology discipline within engineering that deals with the design, implementation, and management of computer networks. These systems contain both physical components, such as routers , switches, cables, and some logical elements, such as protocols and network services .
