About the choice of x86, x64, x86_64, ARM 64, ARM 32 when installing software

Linux installation software FAQ x86 or x64

x64 means that the CPU is a 64-bit version.

x86 means the CPU is a 32-bit version.

If your CPU is 64-bit.You can install 64-bit or 32-bit, and vice versa.

RedHat Linux input at the command line

getconf LONG_BIT

Returning 32 is 32-bit, and returning 64 is 64-bit.

x86 is the standard abbreviation for intel processor-based systems.X has nothing to do with the processor. It is a simple wildcard definition for all *86 systems. It is the number of an Intel general-purpose computer series, and also identifies a set of general-purpose computer instructions. Since the early intel CPU numbers were like8086, 80286 are numbered. Since the entire series of CPUs are instruction compatible, X86 is used to identify the instruction set used. Today's Pentium, P2, P4, and Celeron series all support the X86 instruction system, so allIt belongs to the X86 family.

The CPU chips corresponding to ARM, MIPS, and X86 architectures have been marked in the middle of the download page of the domestic version of the 360 ​​secure browser.Then if you know your CPU, you know the corresponding system architecture.

• ARM: Feiteng, Kunpeng
• MIPS: Godson
• X86: Zhaoxin, Haiguang, Intel, AMD

But when you don't know the CPU and want to quickly know its architecture or system architecture, we can use the Linux command method.

Arch Commands

arch

This is the simplest, direct output schema.aarch64 is the ARM architecture, x86_64 is the X86 architecture; the MIPS architecture does not know what to output, I have never seen it, it is estimated that it also outputs mips directly, we can use the exclusion method, if it is not the first two, it is the MIPS architecture.

uname command judgment

uname -a

The keyword aarch64 in the output is the ARM architecture, the keyword x86_64 is the X86 architecture, and the keyword mips is the MIPS architecture.

File command to determine the structure

file /bin/bash

Similarly, the keyword ARM or aarch64 in the output is the ARM architecture, and the keyword x86_64 is the X86 architecture.
