Normally, the process is in the System32 folder, if two csrss.exe processes (one in the Windows folder) or Windows 9X/Me processes appear in the above system, they are infected with a virus.

For Windows, the concepts of processes and threads are clearly defined, and the concept of a process corresponds to a running instance of a program (instance), while a thread is the smallest unit of execution of a program's code. This means that Windows is defined for processes and threads that are consistent with the process and threading concepts taught in the classic OS course.Provides Api,createthread (

When newcomers join the Go-miami group, they often want to learn the concurrency model. When I first started to hear about the go language, concurrency seemed to be a buzzword in the language. When I saw the video of Rob Pike's go concurrency mode, I thought I should learn the language.
In order to understand how to write more simple and error-prone concurrent programs through the Go language, we first need

When looking-a new process to run on a CPU, the kernel have to consider only the runnable processes(That's, the processes in the task_running state).Earlier Linux version put all runnable processes in the same list called Runqueue. Because it would be tooCostly to maintain the list ordered according to process priorities, the earlier schedulers were compelledTo s
critical section will be suspended and will continue until the thread enters the critical section. After the critical section is released, other threads can continue to seize it and use the atomic method to share resources.
The critical section contains two operation primitives: entercriticalsection (). The leavecriticalsection () in the critical section leaves the critical section.
after the entercriticalsection () Statement is executed, no matter what happens after the Code enters the cri

-- Differences among processes, sessions, and connections
-- ======================================
When using Oracle database, connection and session are one of the words we often encounter. At first glance it looks like one thing, but the fact is not. Zero,One or more sessions. Ah, why? Yes, that's right. This is also the reason we often misunderstand.Each session is independent of other sessions, even mult
Basic ConceptsHook is a platform for message processing in windows. Applications can set sub-processes on the platform to monitor messages in a specified window, the monitored window can be created by other processes. When a message arrives, process it before the target window processing function. The hook mechanism allows applications to intercept and process window messages or specific events. A hook is a

This article aims to introduce the differences between threads and processes. If you have any improper understanding, please kindly advise.
1. What is a process?A process is an instance of a program being executed, including the current value of the program counter, register, and variable.Processes are used to centralize resources. Multiple processes share physical memory, disks, printers, and other resour
Several methods for communication between processes:
In Windows, processes often need to exchange data for data communication. Common methods include:
Use memory ing filesShare memory through DLLUse sendmessage to send the wm_copydata message to another process.
Compared with the previous two complex implementations, wm_copydata is undoubtedly a cost-effective method.
The main purpose of a wm_copydata messa
A simple description of processes and threads.
In a twinkling of an eye, during the summer vacation, the school recruitment in 2015 is about to kick off the curtain. As a computer professional friend, I am often asked a question during the interview: What is the difference between processes and threads, today, I accidentally saw Ruan Yifeng's blog. He used a good analogy to explain them clearly and easily.
1. Linux processes sleep and wake up in Linux. processes that only wait for CPU time are called ready processes, which are placed in a running queue, the status flag of a ready process is TASK_RUNNING. Once a running process runs out of time slices, the scheduler in the Linux Kernel will deprive the process of control over the CPU and select a suitable process fr
Linux Process and thread clone create Java code www.2cto.com [B] Linux Process and thread creation are achieved through clone. the clone function is powerful and has many parameters. clone allows you to selectively inherit the resources of the parent process. You can share a virtual storage space with the parent process like vfork, this creates a thread, and you can not share it with the parent process. You can even choose to create a parent-child relationship between the Process and the parent
Nodejs solves the problem of how to share data among multiple processes in the cluster module, nodejscluster
Aforementioned
Nodejs added a cluster module after v0.6.x to implement multi-process. It uses the child_process module to create and manage processes and increase program performance on multi-core CPU machines. This article describes how to share data using the multi-thread created by the cluster mod
In linux, a process containing the specified file name is killed in batches. I am a Database Administrator (DBA) working in Red Hat 7.0 ). It is often necessary to Kill multiple processes at work. If these processes have common characteristics, you can Kill them with a command. For example, clear all remote connection processes of the Oracle database: www.2cto.co
