Article Title: multi-process viewing and configuration management in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. This section describes not only process viewing, but also what other users are doing because Linux is a multi-user system, therefore, this section also involves multiple users. At the same time, Linux is a multi-process system that often

as a piece of memory in the process address range. Therefore, the process does not need to use file I/O operations,You only need a simple pointer operation to read and modify the file content.Win32 API allows multiple processes to access the same file ing object. Each process receives memory pointers in its own address space. By using these pointers, different processes can read or modify the file content,

It is believed that not only the operating system has the concept of processes and threads, but also the concept of processes and threads in Java, thread threads. Let me tell you the difference between a process and a thread from the point of view of the interview.Let's talk about some basic concepts:What is a computer resourceThe classic von Neumann structure abstracts the computer system into CPU + memory

IIS maximum number of worker processesIIS 6.0 allows the application pool to be configured as a Web garden. To understand the concept of a Web garden, imagine a scenario where you have an IIS 5.0 server and three Web sites, each Web site running the same application, and if IIS 5.0 can automatically follow a circular loop pattern to send requests sequentially to these functionally equivalent, In fact, separate Web sites, separating the load into three different

IIS 6.0 allows the application pool to be configured as a Web garden (Web Garden). To understand the concept of a Web garden, imagine a scenario where you have an IIS 5.0 server and three Web sites, each running the same application, and if IIS 5.0 is able to automatically send requests sequentially in a circular circular mode to these features equivalent, In fact, a separate Web site, which separates the load into three different processes, can form

Basic principle * * *: Normally, a program can only access its own data, and the other processes do not communicate, each process is a separate entity, processes do not need to collaborate between the task can be completed. But as the complexity of the problem increases, a process cannot do all the work, and there must be more than one process that works together to solve the problem faster, better, and mor

Generation and prevention of zombie processes, as well as the use of wait and waitpid In the fork ()/execve () process, assume that the parent process still exists at the end of the Child process, and the parent process fork () has not installed the sigchld signal processing function to call waitpid () when the sub-process ends and the signal is not explicitly ignored, the sub-process becomes a zombie and cannot end

From: Fan forumsMany computer users do not pay too much attention to the process concept. Many people think that they only know that the process can kill the program. As for which processes correspond to which processes, what processes should be killed, and what processes cannot kill these problems, they are rarely con

By using user-level top, ps, and other system tools and Linux kernel protection technologies, we can comprehensively protect the security of important system processes and user processes in Linux systems from the user/kernel levels. The Bell-LaPadula model of the classic information confidentiality security model points out that the process is of the entire computer system. By using user-level top, ps, and

In general, in an operating system, a process is an activity that runs a program on a computer to execute an instance. When we run a program instance, a process is started. The Unix operating system assigns a unique process identification number to each process. Each process has a UID assigned to all processes called by that user. Each process has a priority. The scheduler uses it to determine the next running process. This is what we call the managem

Welcome to the network security forum and interact with 3 million technical staff. The following article describes how to correctly identify illegal processes and how to attach manual anti-virus techniques, I saw the manual anti-virus techniques attached to the correct identification of illegal processes on the relevant website two days ago. I thought it was good and I would like to share it with you. Gener

A process is an execution program. Every time a program runs, a process is created for the operating system and corresponding resources are allocated. Processes can be divided into three categories:1. Interactive Process (I/O)2. batch processing process (CPU)3. REAL-TIME Processes) For an interactive process, generally the cpu time slice is very short, but the priority is high. The batch process occupies a

I'd like to write something about multiple processes and multithreading, and I really love them. But often want to write something about them, but always the psychological trouble, always can't move hands. Today, I finally made up my mind to write something, and then I can tinker with it anyway. Why do I need multiple processes (or multithreading) and why concurrency is required? This question may not be a

ProcessProcess ConceptsProcessProcess is an executing procedure, which is only an informal statement. The process is not just program code, the program code is called the text segment (code snippet), also includes the current activity, the value of the program counter (PC) and the contents of the processor register to represent. In addition, processes include process stack segments (temporary data, function parameters, local variables, addresses), and
