RAID types are illustrated below.
In the following illustration, the following identifier is used:
A, B, C, D, E, and F-represent data blocks.
P1, p2, p3-indicates the parity information block
RAID 0
RAID 0 features:
At least two disks are required.
Distribution of data entries
No redundancy and optimal performance (no image or verification information is stored)
It cannot be used in scenarios with high data security requirements.
RAID 1
ultimately inherited from the abstract class: basevalidationattribute. The main function of this class is to provide abstract encapsulation of error messages and rules for the subclass.
Public abstract class basevalidationattribute: validationattribute
The following fields and methods are used:
1. ruleset: Rule Set. developers can set a rule set for the object to be verified. Different verification methods for a field or attribute can be e

3. Pre-increment/pre-increment operators: two operators borrowed from C. Example:
The Code is as follows:
Var iNum = 10;Console. log (++ iNum); // outpus 11 same as iNum = iNum + 1Console. log (iNum); // outpus 11Console. log (-- iNum); // outpus 10 same as iNum = i
machine, then the heart is to complete the shutdown, if the program can prevent the user shutdown, then is unfriendly program, so in Win7 simply do not allow the user program to prevent the system shutdown. So the return value of Wm_queryendsession here Ture or false is meaningless in Win7, just to be compatible with previous programs, in fact, the shutdown information received in Win7 wm_endsession is True anyway.2.

Why does Nima report an error in Chinese files? In fact, it's not your mistake but the encoding problem.① Encoding and decoding For the Chinese file encoding format is gbk, so under normal circumstances we use Pycharm for debugging is the uft-8 encoding format, so it will report
the value of $1 in the decoding phase, at this time, 1st Ori commands are still in the execution phase. Therefore, the result is not calculated by the 1st Ori commands. If you calculate this value, errors will inevitably occur. 5-1. This situation can be called data correlation between adjacent commands. For openmips, it can also be called data correlation in th
