Today, the editor to share with you is about the introduction of linux system architecture, many people do not know much, today editor in order to let you know more about the linux system architecture, so to sum up the following content, let's look down. I'm sure you'll get something.

Generally speaking, the Linux system has four main parts:

Kernel, shell, file system, and applications. Together, the kernel, shell, and the file system form the basic operating system structure that allows users to run programs, manage files, and use the system.

Partial hierarchical diagram:

1. Linux kernel

The kernel is the core of the operating system, which has many basic functions. It is responsible for managing the process, memory, device drivers, files and network system of the system, and determines the performance and stability of the system.

The Linux kernel consists of the following parts: memory management, process management, device driver, file system and network management.

2. Linux shell

Shell is the user interface of the system, which provides an interface for users to interact with the kernel. It receives the command entered by the user and sends it to the kernel for execution. It is a command interpreter. In addition, shell programming language has many characteristics of ordinary programming language, and shell programs written in this programming language have the same effect as other application programs.

Currently, there are mainly the following versions of shell.

1.Bourne Shell: it was developed by Bell Labs.

2.BASH: GNU's Bourne Again Shell, the default shell on the GNU operating system, and most linux distributions use this shell.

3.Korn Shell: is a development of Bourne SHell and is compatible with Bourne Shell for most of the content.

4.C Shell: is the BSD version of SUN's Shell.

3. Linux file system

A file system is a method of organizing files on storage devices such as disks. Linux systems can support a variety of popular file systems, such as EXT2, EXT3, FAT, FAT32, VFAT and ISO9660.

4. Linux application

Standard Linux systems generally have a set of assemblies called applications, which include text editors, programming languages, X Window, office suites, Internet tools, and databases.

The above is about the details of linux system architecture, after reading it, do you have anything to gain? If you want to know more about it, welcome to the industry information!
