First, the hard diskThe function of a hard disk is quite simple but important, and it is responsible for recording the various data required by the system. The hard disk record data has two aspects, one is the hardware aspect storage principle and the structure, on the other hand is the software aspect data and the file system. The main behavior of a hard
C ++ hardware information to obtain the hard disk serial number and the hard disk serial number
This section describes how to obtain the serial number of a hard disk, not the serial number of a hard disk partition. The core is throughDeviceIoControlInterface to obtain the ve
|--------------------------------------------------------------Although the use of Linux fedora distribution for more than a year, but in fact, there are many details of the knowledge is not careful to think about, such as hardware devices in the Linux/dev directory under some naming rules.First look at the hard drives that we touch the most:now the mainstream hard disk according to the interface can be ca

Disk space utilization is (n-1)/nRAID50: Combines the disks first into RAID5, and then the combined RAID5 Group is synthesized RAID0650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/39/54/wKiom1O4zeWC7bOvAAFAg9dhsA0435.jpg "title=" R50.png "alt=" Wkiom1o4zewc7bovaafag9dhsa0435.jpg "/>RAID50 will have the following characteristics:1, because of the reason of RAID5, so need at least 6 disks to combine into RAID5
program in Linux, and viewing the source will find that the command is to send some IOCTL commands to the disk. But notice that since you can get it, you can set it, so be careful when using this command. Of course, we just want to get a view of the hard disk information, so there is no damage to the hard disk and system. Typically, the-I or-I (uppercase i) opti
U disk appears big and small problem, many times we can through some measures and software to solve, but if there is a hardware failure, many people do not know how to deal with, hardware failures generally appear in the poor quality U disk, because the main board of the U disk
In software encryption protection technology, a common protection method is license authorization based on hardware fingerprint. This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program.
Hardware fingerprint encryption means that after a user obtains and installs the software for free,
How to view hardware information in Windows system with commands, how DOS commands to view hard disk and memory/cpu information? The most direct is: Start → run →cmd open a command prompt, under which you can enter systeminfo execution to see almost all the system information you want to know, even the installed network card and its IP on the machine.
Problem Description: How to view the number of memory
How did you pull the USB stick after you used the U disk? is not a lot of people are directly pulled out, and then put away the next time to use it? The consequences of this do not think there may be damage to the file, or directly to the damage to the U disk, in fact, is very possible. Small knitting today to teach you a way, let this practice become formalized. In fact, U

Optimization of database hardwareHow do I select a CPU?Would you prefer a faster single-core CPU or a higher number of cores?
MySQL has some work that only uses single-core CPUs
MySQL does not support CPU cores more and more faster
Recommendation: mysql5.5 Use a server that does not exceed 32 cores. It is also recommended that the single core frequency be faster CPU.Disk IO optimizationIntroduction to Common RAID levelsRAID0: Also become a stripe, that is, to link multiple disks into

How to view cpu, memory, hard disk, and other hardware information in linux
Note: in Linux, you can view detailed information about each cpu in/proc/cpuinfo. However, for dual-core CPUs, two CPUs are displayed in cpuinfo. It is often mistaken for two single-core CPUs.
