[Linux System] concepts and systems of Linux Thanks to the original author: Vamei Source: http://www.cnblogs.com/vamei I have explained the basic concepts of Linux in this series of articles. The Linux operating system inherits from UNIX. An operating system is a set of software for controlling and using computers. UN

Linux Process Scheduling analysis and linux scheduling AnalysisOverview Multi-process scheduling is essential for the operating system. Some people say that process scheduling is the most important part of the operating system. I think this is an absolute saying, just as many people say that "a function is XX times more efficient than a function", it is out of the actual environment, these conclusions are o

displayed and Linux and an optional initial RAM disk (temporary root file system) are loaded into memory. When the image is loaded, the second stage of the bootloader gives control to the kernel image and the kernel can decompress and initialize it. During this phase, the second stage of the bootloader detects the system hardware, enumerates the system-linked hardware devices, mounts the root device, and then loads the necessary kernel modules. After

In the application of computer systems, Windows is not the only operating platform to be applied, in the field of desktop and server operating system gradually presented a variety of application trends, Linux is undoubtedly the most prominent, Linux is being more and more enterprises and individuals accept, and in the server, The development environment and desktop office area are widely used.Let's take a l

This section describes what happens when a Linux system boots and shuts down, and should be done correctly. If the correct procedure is not followed, the file may be corrupted or missing. Boot and Shutdown overview The process of turning on a computer and causing its operating system to be loaded is called booting. The name comes from a computer pulling itself up to its bootstraps, but the act itself slightly Stic.During startup, the computer first lo

1. Introduction The Linux kernel supports a large number of file system types, and currently it can read and write (or at least read) most file systems. Linux often coexists with Microsoft Windows in a system or hard Linux on the Windows9x/nt file system support is very good, conversely you want to be in Windows with Visual C + + programming while you can look at

Absrtact: This paper deeply analyzes the advanced hiding technologies of files, processes and modules in Linux environment, including: Linux can unload module programming technology, modify memory image directly to system call modification technology, through the virtual file system proc Hide specific process technology. Hidden technology is widely used in computer system security, especially in network att

Tags: cloud computingAfter you start learning Linux, don't think about it in the way that Windows works, because there are really big differences between them, such as the memory management mechanism, the process mechanism, and so on, so the idea of Windows is thrown away. It is essential for beginners to try to tap into the unique potential of Linux with a new concept.1 Be sure to get used to the command l

How to obtain the Linux kernel source codeHow to obtain the Linux kernel source code To download the Linux kernel, you must go to the official website. The website provides two types of file downloads: one is the complete Linux kernel, and the other is the incremental kernel patch. They are all tar archive packages. Un

I've always been using Ubuntu and Fedora as a starter system, but actually what I really want to recommend is arch, after the previous study, perhaps you have a general understanding of Linux, and now if you want to speed up your pace, maybe you can look at this article. If you ask why you are learning Linux, I can only answer just for funI've always been using Ubuntu and Fedora as a starter system, but act

1. Use the first Aid disk group for maintenanceThe first Aid disk group (also known as the Boot/root Disk group) is an essential tool for system administrators. It allows you to start and run a complete Linux system independently. In fact, there is a complete Linux system on the 2nd disk of the first aid disk group, including the root file system, while the 1th disk holds the bootable kernel. It is easy to

Hook Command (Mount)First, introduce the use of the Hook (Mount) command, the Mount command parameters are very many, here is the main point we want to use today.Command format: Mount [-t vfstype] [-O options] Device dirwhich1.-t vfstype Specifies the type of file system, which is not usually specified. Mount automatically selects the correct type. Common types are:Optical or optical Image: iso9660DOS FAT16 file system: MSDOSWindows 9x FAT32 file system: VFATWindows NT NTFS file system: NTFSMoun
