32 bits.
Differences between i386/i686/x86-64/ in Linux distributions
1. i386 is suitable for all 32-bit CPUs of Intel and AMD and via X86 Architecture of 32 cpu. The intel platform includes 8086, 80286, 80386, 80486, Pentium series (1.2.3.4), Celeron series, Pentium D series and centrino P-M, core duo, etc.
2, X86_64 is suitable for Intel's Core 2 Duo , Centrino Core 2 Duo, and Xeon and AMD Athlon64/x2, Sempron64/x2, Duron64 and other 64-bit CPUs using X86 architecture.
3. I686 is just a subset of i386. The supported CPUs start from Pentium 2 (686), and previous models are not supported.
Related introduction:
Linux is a set of Unix-like operating systems that are free to use and freely disseminated. It is a multi-user, multi-task, multi-threading and multi-CPU based on POSIX and UNIX. operating system.
It can run major UNIX tool software, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.
The Linux operating system was born on October 5, 1991 (this is the first time the date was officially announced to the outside world). There are many different Linux versions of Linux, but they all use the Linux kernel. Linux can be installed on a variety of computer hardware devices, such as cell phones, tablets, routers, video game consoles, desktop computers, mainframes, and supercomputers.
Strictly speaking, the word Linux itself only refers to the Linux kernel, but in fact people are accustomed to using Linux to describe the entire operating system based on the Linux kernel and using various tools and databases of the GNU Project.
File type
Ordinary file (regular file): It is a file for general access. Among the attributes displayed by ls -al, the first attribute is [-], such as [- rwxrwxrwx]. In addition, according to the content of the file, it can be roughly divided into:
1. Plain text file (ASCII): This is the most common file type in Unix systems. It is called plain text file because The content can be read directly, such as numbers, letters, etc. Setting files almost always belong to this file type. For example, use the command "cat ~/.bashrc" to see the contents of the file (cat reads the contents of the file).
2. Binary files: The system actually only recognizes and can execute binary files. Executable files in Linux (scripts, text batch files are not counted) are in this format. For example, the command cat is a binary file.
3. Files in data format (data): Some programs will read files in certain formats during operation. Those files in specific formats can be called data files.
For example, when a user logs in, Linux will record the login data in the /var/log/wtmp file. This file is a data file that can be read out through the last command. But when using cat, garbled characters will be read. Because it is a file in a special format.

The five core components of the Linux operating system are: 1. Kernel, 2. System libraries, 3. System tools, 4. System services, 5. File system. These components work together to ensure the stable and efficient operation of the system, and together form a powerful and flexible operating system.

The five core elements of Linux are: 1. Kernel, 2. Command line interface, 3. File system, 4. Package management, 5. Community and open source. Together, these elements define the nature and functionality of Linux.

Linux user management and security can be achieved through the following steps: 1. Create users and groups, using commands such as sudouseradd-m-gdevelopers-s/bin/bashjohn. 2. Bulkly create users and set password policies, using the for loop and chpasswd commands. 3. Check and fix common errors, home directory and shell settings. 4. Implement best practices such as strong cryptographic policies, regular audits and the principle of minimum authority. 5. Optimize performance, use sudo and adjust PAM module configuration. Through these methods, users can be effectively managed and system security can be improved.

The core operations of Linux file system and process management include file system management and process control. 1) File system operations include creating, deleting, copying and moving files or directories, using commands such as mkdir, rmdir, cp and mv. 2) Process management involves starting, monitoring and killing processes, using commands such as ./my_script.sh&, top and kill.

Shell scripts are powerful tools for automated execution of commands in Linux systems. 1) The shell script executes commands line by line through the interpreter to process variable substitution and conditional judgment. 2) The basic usage includes backup operations, such as using the tar command to back up the directory. 3) Advanced usage involves the use of functions and case statements to manage services. 4) Debugging skills include using set-x to enable debugging mode and set-e to exit when the command fails. 5) Performance optimization is recommended to avoid subshells, use arrays and optimization loops.

Linux is a Unix-based multi-user, multi-tasking operating system that emphasizes simplicity, modularity and openness. Its core functions include: file system: organized in a tree structure, supports multiple file systems such as ext4, XFS, Btrfs, and use df-T to view file system types. Process management: View the process through the ps command, manage the process using PID, involving priority settings and signal processing. Network configuration: Flexible setting of IP addresses and managing network services, and use sudoipaddradd to configure IP. These features are applied in real-life operations through basic commands and advanced script automation, improving efficiency and reducing errors.

The methods to enter Linux maintenance mode include: 1. Edit the GRUB configuration file, add "single" or "1" parameters and update the GRUB configuration; 2. Edit the startup parameters in the GRUB menu, add "single" or "1". Exit maintenance mode only requires restarting the system. With these steps, you can quickly enter maintenance mode when needed and exit safely, ensuring system stability and security.

The core components of Linux include kernel, shell, file system, process management and memory management. 1) Kernel management system resources, 2) shell provides user interaction interface, 3) file system supports multiple formats, 4) Process management is implemented through system calls such as fork, and 5) memory management uses virtual memory technology.
