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.
