understand the GUID partitioning scheme. Don't forget, the speed of hardware development is always surprising. 1.5TB of hard drives are already on the market, 2TB or more of the capacity of the hard disk will soon become popular, EFI-based motherboards are also being sold. The GUID partitioning scheme will eventually become mainstream.As a section software,DiskgeniusThe GUID partition table is supported starting with version 3.1. This is the first partition software that supports GUID partition

The other is to test the other plate! is to use the exclusion method to find! If it is an array box, it will show the disc!

Cause of the task: because the newly purchased server needs to mount the disk to the operating system, in order to mount the disk first to partition the disk, then create the file system, and finally mount the disk to a directory on the operating system.The MBR (Master Boot Record) is a traditional partitioning mechanism that is applied to the vast majority of PC devices that use the BIOS.1.MBR supports 32bit and 64bit systems2.MBR limited number of supported partitions3.MBR only supports hard d

the execution of recursive algorithms. As shown in Figure 9-9-7, it is the recursive process of {50,10,90,30,70,40,80,60,20} in the quick sort process. Since our first keyword is 50, which is exactly the middle value of the sequence to be sorted, the recursive tree is balanced, and the performance is better at this time.In the optimal case, the partition is divided evenly every time, if you sort n keywords, the depth of the recursive tree is ⌊log 2n⌋+1 (⌊x⌋ represents the largest integer that i

T (n) ≤nt (1) + (log2n) xn= O (NLOGN) In other words, in the optimal case, the time complexity of the fast sorting algorithm is O (NLOGN). In the worst case, the sequence to be sorted is either positive or reverse, and each partition has only one sub-seq

If you need it, you can refer to the sup method to return the superscript string defined by the HTML sup tag attribute. The syntax is as follows: The Code is as follows: Str_object.sup () Tip: This method does not
