What is the difference between CentOS and Linux

1. Linux refers to the operating system kernel, and CentOS refers to the GNU/Linux operating system.

2. The Linux system kernel plus a large number of free software provided by GNU is a complete GNU/Linux distribution, and CentOS is one of many distributions.

Linux is just an operating system kernel, and GNU provides a large number of free software to enrich various applications on top of it. Therefore, strictly speaking, the word Linux itself only refers to the Linux kernel, but in fact people have become 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.

Linux software based on these components is called a Linux distribution. Generally speaking, a Linux distribution package contains a large number of software, such as software development tools, databases, web servers (such as Apache), X Window, desktop environments (such as GNOME and KDE), office suites (such as OpenOffice.org), etc. .
