Many people have encountered the server RAID5 hang out, often after a disk, the second disk also immediately hung up.
Reference: RAID 5 is also a data parity to ensure data security, but it is not a separate hard disk to store data parity bit, but to the data section of the check bit interaction on each hard disk. In this way, any hard drive that is damaged can reconstruct the corrupted data based on the p

Input and Output status: The configuration process uses an I/O device, such as a tape drive.
4. How the Process control block PCB is organized1gt. Linear table mode: Regardless of the state of the process, all PCBs are kept in the system area of the memory continuously. This approach applies to situations where the number of processes in the system is not large. 2> Index Table Method: This method is an improvement of
reflection:Maybe someone would ask Python not have two built-in functions exec and eval? They are also able to execute strings. Like what:
12345
exec("print(‘haha‘)")结果:haha
Why not just use them? Why bother using getattr,__import__ so hard?In fact, in the example above, the core topic around is how to use strings to drive different events, such as importing modules, calling functions, and so on, these are Python refle

JS design is an important factor for users to have a good experience on the web. However, many Web pages do not test JS.This is partly because JS is difficult to test. Interaction and logic are dependent on the user's interaction with the Web page, which is difficult.The JS framework also does not support simple unit testing. The to

Do you think it's just a CPU when you lift a phone processor? What, you always think so? Well, boy, it's naïve.
Have you heard of the "core M" processor in the PC field? The processor, which can be plugged into a tablet, laptop or computer, is not a single processor, but is called the "Soc" (on-chip system), and the more integrated mobile processor is naturally a member of the SOC.
What do you mean, SOC? You can think of it as a combination of chips packaged in a chip that would otherwise have
How to optimize the management of memory, improve the use of memory efficiency, as far as possible to improve the speed of operation is a concern for everyone. Here are 5 ways to improve the efficiency of memory usage and optimize memory management in the Windows operating system.

z60t doesn't offer a dedicated graphics card, just Intel's integrated multimedia accelerator, but with a fast processor and lots of ram you can still play a number of games, even newer ones, as long as they don't demand lots of polygon shading or include fast moving 3D objects that scale rapidly. I played a few demo games, one of which was a sports game named pro evolution soccer 5 and had no issues running the games.
