This article will explain in detail how to view server hardware information on Linux. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

What is Linux system Linux is a free-to-use and free-spread UNIX-like operating system, is a POSIX-based multi-user, multi-task, multi-threaded and multi-CPU operating system, using Linux can run major Unix tools, applications and network protocols.
