Today, I would like to share with you the relevant knowledge of linux is the kernel. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Linux is a kernel, not a complete operating system. Linux only realizes the simple management of computer resources, there is no compilation tools and other necessary operating system tools integrated into it, only one operating system kernel is implemented, so it is not a complete operating system, a variety of distributed versions are operating systems.

The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

Linux is the kernel

Linux is a kernel, not a complete operating system. Various distributions are the real operating systems.

It cannot be called a real or productive operating system, because it only implements the simple management of computer resources (that is, the implementation of an operating system kernel). However, there are no other necessary tools for the operating system, such as compilation tools.

In the early days of Linux, the term Linux was actually short for the kernel of the Linux operating system. The Linux kernel is not an operating system but implements the management of computer hardware. It is the base of the operating system and usually includes the following aspects:

Memory management process management, in fact, is the management of CPU equipment management, such as mouse, keyboard and other file management, that is, the management of hard disks and other storage devices, abstracted as file system network device management, network devices can be regarded as a special case

Because the Linux kernel is open source and free, more and more companies and individuals participate in the development of Linux kernel. And many open source projects are also ported to Linux, so that Linux is gradually plump up.

There are many Linux distributions, for example, we see a lot of Ubuntu, Redhat, Suse and so on, very many. For the traditional concept, the operating system should be a fully functional system, which includes not only the kernel, but also a lot of application software. As a result, the meaning of Linux was gradually transformed from Linux to the Linux operating system, while the kernel of Linux was called the "Linux kernel" to make it easier to distinguish.

Linux operating system and various distributions

Earlier, we briefly introduced the Linux operating system, kernel, and distribution. For Linux operating system, it is a whole, including Linux kernel, system library and system program. Linux kernel is the most basic part of it. It realizes the management of hardware resources and provides a general interface to use these hardware resources.

Since the release of the LInux kernel in 1991, many companies have joined in and built their own operating system versions based on the kernel, such as Redhat, Debian, Suse and so on. Figure 2 shows the evolution of Linux distributions from 1991 to 2007 (high-definition picture, private email, linuxtl). It can be seen that there are no less than 20 distributions by 2007.
