What is the difference and connection between Linux and Ubuntu? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Ubuntu is an open source GNU/Linux operating system built by a global professional development team (Canonical Ltd) based on Debian GNU/Linux, supporting x86, amd64 (x64), and ppc architecture. Ubuntu has made a great contribution to the popularity of GNU/Linux, especially the popularity of desktops, thus enabling more people to share the achievements and highlights of open source.

Linux kernel is an open source computer operating system kernel. It is a Unix-like operating system written in C language and conforms to the POSIX standard.

The Linux kernel was first developed by Finland's Linus Torvalds to try to provide a free Unix-like operating system on Intel's x86 architecture. The main modules are divided into the following parts: storage management, CPU and process management, file system, device management and driver, network communication, and system initialization.

Linux and Ubuntu:

People often say that Linux operating system, Ubuntu operating system, this name is incorrect, strictly speaking, Linux is not an operating system, but belongs to a kernel of the operating system.

Because Linux is open source and free, programmers can change it according to their own interests and inspiration and combine it into the operating system they want.

There are many operating systems with Linux as the kernel. We call this operating system the distribution version of linux, or directly use linux to refer to the operating system with linux as the kernel.

Linux and Unix

Linux is usually called similar to Unix, but there is a big difference between the two.

The manufacturers of unix are basically co-developed by hardware and software, so the versatility of unix system is not high, and it is mainly designed specifically for special hardware.

Therefore, the performance and stability are extremely good, while linux is indeed a general-purpose system, and most manufacturers do not produce their own hardware (only a few like redhat

This kind of manufacturer does this, so it makes a lot of money), so the biggest advantage of linux is its good compatibility, but this determines that the performance can not be played to the extreme.

Commercially speaking, due to the above performance differences, there are two different business models. Unix hardware and software are sold together and are very expensive (except freebsd).

On the other hand, linux only sells software, and most of them are free (there are still a few manufacturers like radhat who follow the path of unix); therefore, unix is suitable for large enterprises, while linux

Suitable for small and medium-sized enterprises and individuals

Because linux is open source free software, different people, different communities or companies can "assemble" an operating system with the linux kernel according to their own ideas. Ubuntu is a linux distribution, which means that ubuntu is an operating system with linux as its kernel. So in fact, ubuntu and linux are not the same concept at all. If Linux refers to human beings, then Ubuntu is just a person named Ubuntu.
