Linux and Ubuntu:

大家经常会说Linux操作系统，Ubuntu操作系统，这种叫法是不正确的，严格意义上讲，Linux并不是操作系统，而是属于操作系统的一个内核

Since Linux is open source and free, programmers can customize it according to their own interests and Change it with inspiration and combine it into the operating system you want;

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

Linux and Unix

通常称linux是类似Unix的，但是两者有很大的区别

Unix manufacturers basically jointly develop software and hardware, so Unix systems are not very versatile and are mainly developed for specialized hardware. Special design, so the performance and stability are extremely good; and Linux is indeed a general-purpose system, and most manufacturers do not produce their own hardware (only a few manufacturers like redhat do this, so they make a lot of money), so The biggest advantage of Linux is its good compatibility, but this determines that the performance cannot be maximized...

Commercially speaking, due to the above performance differences, it has led to two different business models, Unix Software and hardware are sold together and are very expensive (except for freebsd), while Linux only sells software, most of which are free (manufacturers like Radhat who follow the Unix path are still in the minority); therefore, Unix is ​​suitable for large enterprises, while Linux is suitable for small and medium-sized enterprises and individuals. .

Linux and Ubuntu

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