CRC Algorithm in Computer Network Communication

This article has analyzed the insufficiency of the traditional teaching administration system, proposed that through inserts the way of regulation storeroom to realize in the procedure active database-based the teaching administration system, through the practical research showed that this system can provide the real-time, all-round service on own initiative, and active service mechanism is highly effective, feasible In this paper, it studies one of the error check cont rols of the communications of computers network . Cyclic Redundancy Check ( CRC ) . It introduces the principle of CRC, the algorithms of CRC, the algorithms analysis of CRC, the program of CRC and the functions & features of CRC. The algorithms of CRC need not to design circuit of hardware in addition. It improves the speed of the communications of computer s network an d checks the message correctly.
