Graphic RAID 0, RAID 1, RAID 5, RAID 10 RAID (Redundant Array of Independent Disk Independent Redundant Disk Array) technology was proposed by the University of California at Berkeley in 1987, initially to combine small cheap disks to replace large expensive disks, at the same time, we hope that when the disk fails, data access will not be damaged and a certain level of data protection technology will be de

For example, there is a variable $ aarray (12.1, 10, string); to convert it into an array (12.1,

to one parity message, RAID 5 has a higher disk space utilization than RAID 1 and a relatively low storage cost.4.Raid 10 is a raid 0 with Raid1 parity implements stripe set mirroring, so it inherits the RAID0 's fast and RAID1 security. We know that RAID 1 is a redundant backup array here, while RAID 0 is responsible for reading and writing the data array. In

don't need to care about how internal implementation is implemented. We just need to set the relationship between objects in advance, and then tell UnityContainer what I need when necessary, unityContainer will send us what we need directly. (These metaphors may be incorrect, but they are the best one I can think) Use code to achieve object Association Registration: First, let's look at a simple example:View sourceprint? 01 public interface IClass 02 {
