Understand the classification of Linux operating systems

Linux operating system is an open source, Unix-like operating system that is widely used in various types of computing devices. It was first launched in 1991 by Finnish programmer Linus Torvalds, and after years of development and refinement, it has now become one of the most popular operating systems in the world. However, due to the open source nature of Linux, there are many different kinds of Linux operating systems, each with different characteristics and uses. This article will explore several major classifications of Linux operating systems.

1. Linux Distribution (Distribution)

Linux distribution refers to the combination of Linux kernel, application software, package manager, documentation, etc. operating system together. Since the Linux kernel itself does not contain a user interface or other common applications, the importance of Linux distributions is that they provide a complete operating system environment for users to use.

There are many well-known Linux distributions on the market, such as Ubuntu, Fedora, Debian, CentOS, Arch, etc. Each distribution has its own characteristics and target user group. For example, Ubuntu focuses on desktop usability, while CentOS focuses more on server applications.

2. Server version and desktop version

The operating system based on the Linux kernel can be divided into server version and desktop version. The server version is aimed at users who build a server environment and usually provides more powerful network functions and stability. In contrast, the desktop version is mainly for individual users, providing more graphical user interface and convenient operating experience.

The more common server versions include CentOS, Ubuntu Server, etc., while the desktop versions include Ubuntu, Fedora, etc.

3. Embedded Linux

Embedded Linux refers to the Linux system that is embedded in various embedded devices. This kind of Linux system is usually cut into a compact version to save resources and improve performance. Embedded Linux is widely used in various smart devices, such as smartphones, smart TVs, smart home devices, etc.

Common embedded Linux systems include Android, OpenWrt, BusyBox, etc.

4. Real-time Linux

Real-time Linux is a Linux kernel version specially used for real-time systems, which can ensure that tasks are completed within a certain time range Completed in-house, with extremely high reliability and stability. Real-time Linux is widely used in industrial control, robotics, aerospace and other fields.

Common real-time Linux systems include RTLinux, Xenomai, etc.

In general, the Linux operating system has been widely used in different fields after years of development and growth. By understanding the different types of Linux operating systems, users can choose the most suitable version to use according to their own needs, thereby better utilizing its functions and advantages.
