Linux system composition

In computer system applications, Windows is definitely not the only operating system platform to be used. In the field of desktop and server operating systems, Linux is undoubtedly the most eye-catching. Linux operating systems are accepted by more and more enterprises and individuals, and are widely used in servers, development environments, and desktop office fields. Last year, most of the Chinese operating systems were developed based on Linux.

Method/step

1. Linux system composition:

   The Linux operating system consists of the Linux kernel and various peripheral programs. Linux Kernel is a special software program used for core operations such as CPU and memory allocation, process adjustment, and device driver. It focuses on hardware. Peripheral programs include user instruction Resolvers, network service programs, graphic desktop programs, and other application-oriented software programs.

2. Linux Kernel:

   For the operating system, the kernel is as important as a human heart, and is the most critical component of the entire Linux operating system. It is no exaggeration to say that without the appearance of the Linux kernel, there will be no Linux operating system today.

   The Linux kernel was initially released in 1991 by Linus Torvalds, a Finnish college student, mainly using C language and a small part of assembly language.

   The official website of Linux kernel is http://www.kernel.org/from which you can download the source code of kernel files of various versions that have been released, because the Linux kernel is open source, so everyone can modify and compile the Linux Kernel on their own.

   The Linux logo is the little penguin named Tux.

3. Linux system peripheral Program

   Most of the peripheral programs that constitute the Linux system are open-source software from GNU projects or other organizations, such as the top famous C language compilation tool GCC, command parser program bash, and website service program httpd, therefore, the most accurate meaning of the Linux operating system is "GNU/Linux operating system"

   The GNU name is abbreviated as "GNU is Not UNIX. The goal is to write a large number of commercial software compatible with UNIX operating systems that can be freely transmitted and used to replace UNIX systems. GNU official site located at: http://www.gnu.org/

   Open-source software is open-source software. One of its most important features is open-source software. Everyone can obtain all the source code of open-source software. The emergence of open-source software poses a great challenge to traditional commercial software models (closed source code.

4. Release version of Linux

   Since the Linux kernel is also an open-source software, any company or even individual can package the Linux kernel and free software into a complete Linux operating system, various Linux Release versions have emerged, the kernel and software package they use are basically similar, but the specific operations and usage are slightly different.

   Mainstream Linux branches include 1. Red Hat Series 2. Suse Series 3. Debian Series

   Among them, the famous Ubuntu is a release version based on Debian, with a gorgeous desktop. Deepin Linux in depth in China is also a release version based on Ubuntu. If you are interested, Baidu can get more information.

   The Red Hat series Linux released by Red Hat has a wider enterprise user base and represents the fact standard of the Linux operating system. The most widely used Linux versions include:

   1. Red Hat Enterprise Edition is an official version launched by Red Hat for enterprise applications.

   2. The ora community edition is mainly designed for individual Desktop Users and maintained by the Fedora community.

   3. The CentOS community edition enterprise operating system is a Community edition Linux system reconstructed based on the source code components of Red Hat Enterprise Edition. It almost retains all functions of Red Hat Enterprise Edition. Because it can be downloaded for free, it has become the first choice for most network companies. Its official website is: http://www.centos.org/
