). the greater the value, the lower the priority; Virtual size of VSZ process; Number of RS resident pages; TTY terminal ID. The question mark indicates that there is no end, that is, the system itself. STAT process status D Uninterruptible sleep (usually IO) R is running and can be crossed in the queue; S is in sleep state; T stop or be tracked; W enters the mem

I. Purpose of the experimentIn batch processing system, time-sharing system and real time system, the number of processes is generally larger than the number of processors, which results in each process competing for the processor. This requires the process scheduler to foll

Process switching and general execution of the systemFirst, the process of scheduling the three time:1. Interrupt processing (including clock interrupts, I/O interrupts, system calls, and exceptions), call schedule () directly, or call schedule () based on the need_resched tag when returning to the user state;2. Kernel thread can directly call schedule () for

When the Android system is started, "init =/init" is usually set in the kernel boot parameters. In this way, if the kernel is successfully mounted to the file system, the INIT program in the root directory is run first. What does this program do? We only have rfsc (readthe fucking source code )!! The INIT program source code is in system/CORE/init of Android offi

Through the reconstruction of the Hosting system, we can understand the HTTP request processing process in the ASP. NET Core pipeline [Up]: The pipeline is used to process the request, and the hostingcore It is called ASP. NET Core is a Web development platform, rather than a simple development framework, because it has a highly scalable request processing pipeli

Inittab file profiling [Inittab file format]: id: runlevels: action: process [Filter out rows starting with #: grep-v "^ #"/etc/inittab | more] Id: identifier, which is unique and can contain two digits or letters. Runlevels: indicates the running level. You can specify multiple runlevels. If this parameter is left blank, the value ranges from 0 ~ 6. Execute all running levels Action: Specifies the running status

The process itself thought of another way to do To modify the registry first: Hkey_local_machine\\system\\currentcontrolset\\service\\perfproc\\performance Under: Disable performance counters is changed to 0 Get the current process of the system and add it to the listbox: system.diagnostics.process[] Processoncompute

IntroductionProcess synchronization is an operating system level concept, in the context of multi-channel programs, there are different constraints, in order to coordinate this mutual restrictive relationship, the realization of resource sharing and process collaboration, so as to avoid conflicts between processes, the introduction of process synchronization.Crit

　　In general, viruses are hidden in the following three ways: 1, steal a single character change 2, the replacement system in the corresponding process name 3, the virus to run the required DLL file into the normal system process 　　Second, how to identify the virus process
