Class responsibility collaborator (CRC) model (Beck cunnheim 1989; Wilkinson 1995; Ambler 1995) is a way to collect and organize cards. A crc card consists of three parts: 1. First, a class similar to a realistic object; 2. specify the responsibilities that such a card should know or be responsible; 3. Identify other types that interact with each other in the process of implementing such duties as collabor

Redis has problems with data errors when it comes to network transmissions and RDB backups, so it uses data validation. Includes a validation algorithm that uses the CRC64. The CRC test principle is actually the addition of an R-bit binary test code (sequence) after a P-bit binary data sequence, thus constituting a binary sequence with a total length of n=p+r bits; There is a particular relationship between the code attached to the data sequence and t

When comparing files using the Beyond Compare file Comparison tool , it will have a save function to store the comparison session records, but in order to be more insured, the user's friends can also back up important comparison session records by saving the snapshot. CRC means the cyclic redundancy code check, is the use of division and the remainder of the principle of error detection, the following for you to share the Beyond compare save snapshot

The process of checking errors using CRC can be simply described as follows: the sender follows certain rules based on the K-bit binary code sequence to be transmittedGenerates an R-bit supervision code (CRC Code) for verification, which is attached to the original information.To form a new binary code sequence consisting of K + R bits and then sent out. At the receiving end, check the rules observed betwee

To check the communication reliability, You Need To 'check'. The verification is performed from the data itself. It relies on a certain form of mathematical conventions for inspection. The verification result is reliable or unreliable, if it is reliable, the data will be processed. If it is not reliable, it will be discarded for re-transmission or repair. The CRC code is composed of two parts. The first part is the Information Code, that is, the inf
