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.
- 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.

- 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.
- 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.
- 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.

Before starting, open the "Software" tool in Fedora Workstation, or other tools using the official repository. Select the "Add-ons" category in the selection bar. Then select "Fonts" within the category. You'll see the available fonts similar to the ones in the screenshot below: When you select a font, some details will appear. Depending on several scenarios, you may be able to preview some sample text for the font. Click the "Install" button to add it to your system. Depending on system speed and network bandwidth, this process may take some time to complete

How to use one network cable to connect two ubuntu hosts to the Internet 1. Prepare host A: ubuntu16.04 and host B: ubuntu16.042. Host A has two network cards, one is connected to the external network and the other is connected to host B. Use the iwconfig command to view all network cards on the host. As shown above, the network cards on the author's A host (laptop) are: wlp2s0: This is a wireless network card. enp1s0: Wired network card, the network card connected to host B. The rest has nothing to do with us, no need to care. 3. Configure the static IP of A. Edit the file #vim/etc/network/interfaces to configure a static IP address for interface enp1s0, as shown below (where #==========

Different CPU architectures mean that running DOS on the Raspberry Pi is not easy, but it is not much trouble. FreeDOS may be familiar to everyone. It is a complete, free and well-compatible operating system for DOS. It can run some older DOS games or commercial software, and can also develop embedded applications. As long as the program can run on MS-DOS, it can run on FreeDOS. As the initiator and project coordinator of FreeDOS, many users will ask me questions as an insider. The question I get asked most often is: "Can FreeDOS run on a Raspberry Pi?" This question is not surprising. After all, Linux runs very well on the Raspberry Pi
