There are three types of user interfaces in Linux: 1. Command line interface, a user interface based on text input. Users enter commands through the keyboard to operate the computer, which has high flexibility and speed; 2. Graphical user interface , a user interface that uses graphical elements and windows to interact, easy to use and learn; 3. Web user interface, a user interface built on the functions provided by a web server, can work on various platforms and devices, and Interact with many different services through an Internet connection.
The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.
Linux user interfaces are usually divided into the following three types:
1. Command line interface (CLI):
The command line interface is a A text input user interface where the user enters commands through the keyboard to operate the computer. CLIs generally offer greater flexibility and speed, and consume less system resources. The CLI is very useful for advanced users who are familiar with the command line.
2. Graphical User Interface (GUI):
A graphical user interface is a user interface that uses graphic elements (such as icons, buttons, and menus) to interact with windows. interface. A GUI is a user interface that is easy to use and learn, especially for users who are less familiar with command lines or programming languages.
3. Web user interface (Web UI):
The Web user interface is a user interface based on the functions provided by a Web server. It works across platforms and devices, and interacts with many different services over an Internet connection. Web interface is usually a common pattern for web applications, such as online editors, social media, email, e-commerce, etc.
The main difference between these three user interfaces is the way they interact with each other.
CLI requires users to remember a large number of commands and options, but CLI is more flexible and primitive, allowing for almost unlimited programming.
GUI emphasizes the user's intuitive feeling and visual effects, and is especially suitable for junior users who are inferior to CLI. However, in some cases, the graphical method cannot meet the needs of users.
The Web interface is an important part of the computerization process. It provides the interactivity of traditional GUI and a certain degree of programmability, while supporting most

Maintenance Mode in Linux: When and Why to Use ItApr 25, 2025 am 12:15 AMThe timing and reasons for using Linux maintenance mode: 1) When the system starts up, 2) When performing major system updates or upgrades, 3) When performing file system maintenance. Maintenance mode provides a safe and controlled environment, ensuring operational safety and efficiency, reducing impact on users, and enhancing system security.
Linux: Essential Commands and OperationsApr 24, 2025 am 12:20 AMIndispensable commands in Linux include: 1.ls: list directory contents; 2.cd: change working directory; 3.mkdir: create a new directory; 4.rm: delete file or directory; 5.cp: copy file or directory; 6.mv: move or rename file or directory. These commands help users manage files and systems efficiently by interacting with the kernel.
Linux Operations: Managing Files, Directories, and PermissionsApr 23, 2025 am 12:19 AMIn Linux, file and directory management uses ls, cd, mkdir, rm, cp, mv commands, and permission management uses chmod, chown, and chgrp commands. 1. File and directory management commands such as ls-l list detailed information, mkdir-p recursively create directories. 2. Permission management commands such as chmod755file set file permissions, chownuserfile changes file owner, and chgrpgroupfile changes file group. These commands are based on file system structure and user and group systems, and operate and control through system calls and metadata.

Linux: A Deep Dive into Its Fundamental PartsApr 21, 2025 am 12:03 AMThe core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.
Linux Architecture: Unveiling the 5 Basic ComponentsApr 20, 2025 am 12:04 AMThe five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.
Linux Operations: Utilizing the Maintenance ModeApr 19, 2025 am 12:08 AMLinux maintenance mode can be entered through the GRUB menu. The specific steps are: 1) Select the kernel in the GRUB menu and press 'e' to edit, 2) Add 'single' or '1' at the end of the 'linux' line, 3) Press Ctrl X to start. Maintenance mode provides a secure environment for tasks such as system repair, password reset and system upgrade.
Linux: How to Enter Recovery Mode (and Maintenance)Apr 18, 2025 am 12:05 AMThe steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.
