In Linux, "X11" refers to "X Window System", which is a graphical window management system; "X11" was born in Unix and OpenVMS, and is the standard for establishing graphical user interfaces in the traditional Unix environment. Toolkits and protocols, and the graphical management interface under the Linux operating system are also developed based on the X11 runtime library.

What is x11 in Linux
X11 is also called the X Window system, which is a graphical window management system. It was born in Unix and OpenVMS and is a standard toolkit and protocol for building graphical user interfaces in the traditional Unix environment.
The graphical management interface (GNOME, KDE) under the Linux operating system is also developed based on the X11 runtime library.
X Window System (X Window System, also often called X11 or X) is a software window system displayed in bitmap mode. Originally developed as research at MIT in 1984, it has since become an operating protocol for standardized software toolkits and display architectures used by operating systems such as UNIX, UNIX-like, and OpenVMS. The X Window System uses software tools and architectural protocols to create graphical user interfaces for operating systems, and has since gradually expanded to apply to a variety of other operating systems. Almost all operating systems now support and use X. More importantly, today's well-known desktop environments-GNOME and KDE are also built on the X Window System.
X Window System is referred to as X, or X11, or X-Windows. It is called X because X is located after W in the alphabet, and W is the GUI system used by MIT before X.
The reason why it is called X11 is because in 1987, the X Window System has evolved to the 11th version. All subsequent Xs are developed based on the X11 version (the changes are not big) ). For convenience, we will refer to X Window System as X in the future.
Extended knowledge
Since Only in this way can there be a truly usable and executable entity, which can be called an implementation entity. Among the implementations currently developed and written based on the standard architecture of X, X.Org is the most common and popular.
In the illustration, the X server obtains input information from the keyboard and mouse, and then displays the input feedback on the screen, while the web browser and terminal emulator perform the run on the computer system.
In addition, the client also maintains contact with remote machines and servers through the network to ensure that the message status is updated. Such a mechanism and architecture can make remotely run software run as if it were running on the local machine.

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.
Linux's Essential Components: Explained for BeginnersApr 17, 2025 am 12:08 AMThe core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.
