SQL Server OS, thread scheduling adopts the cooperative mode instead of the preemption mode. This is because all the tasks in these databases are within the SandBox of SQL Server. SQL Server fully believes in its threads, so unless the thread voluntarily gives up the CPU, SQL Server OS will not forcibly deprive the CPU of the thread. In this way, although the Worker switchover is still performed through the Context Switch of Windows, this cooperation mode will greatly reduce the number of Conte

Analysis of selinux and Xinxing linuxselinux in Linux
Selinux is a program initiated by the US National Security Agency. It aims to reinforce the system to a level that can reach the military level. This also provides more powerful protection for Linux security.
The so-called DAC is autonomous access control, that is, in order to be able to share files with other users, each user can only change the permissions of other users of this file before using
MAC system provided in Linux kernel 2.6. For the currently available Linux security module, SELinux is the most comprehensive and fully tested. it was established based on 20 years of MAC research. SELinux combines multi-level security or an optional multi-class policy in a type forced server, and adopts the role-based access control concept. Most people who use SELinux-ready releases, such as Fedora, Red Hat Enterprise Linux (RHEL), Debian, or Gentoo. They enable SELinux in the kernel and prov

SELinux is a project launched by the National Security Agency to strengthen the system to a level that can reach the military. This also provides a stronger guarantee for Linux security.The so-called DAC, is the autonomous access control, that is, every user in order to be able to implement and other users to share files, before using ACLs, only by changing the permissions of other users of this file, but this method to the security of the system has
Address cycle mapping
Typically, the DMA support layer uses a 32-bit bus address. It is constrained by the DMA mask of the device
The PCI bus also supports 64-bit address mode. Dual address cycle (DAC)

First of all, does the sound quality of CD machine compare to computer?
This is not necessarily, although the CD machine in the appearance and the computer very different, but its structure is the same, the CPU in the computer is equivalent to the CD machine in the special operation of the chip; the CD-ROM in the computer is equivalent to the turntable system in the CDs machine; The Independent/integrated sound card in the computer is equivalent to the DAC

Resolution is usually defined as the number of bits, and the conversion with higher resolution can reduce quantization noise. 3, RMS: indicates a valid value or a valid DC value for the AC signal. For a sine wave, the RMS is 0.707 times times the peak value, or 0.354 times times the peak-value. 4, spurious-free dynamic range (SFDR): sine wave fin (for the ADC refers to the input sine wave, for ADC/

The concept of SELinux:Selinux[security Enhanced Linux (Secure hardened Linux)], is an implementation of a Mac that works in the kernel (Mandatory access control, mandatory access controls), The goal is to explicitly indicate which resources a process can access (files, network ports, and so on). The purpose of the mandatory access control system is to enhance the ability of the system to defend against 0-day attacks (exploits that exploit the vulnerabilities that have not been exposed).
