What is the Linux system?
Linux, whose full name is GNU/Linux, is a set of UNIX-like operating system that is free to use and spread freely. It is mainly inspired by the ideas of Minix and Unix. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and Unix.
Linux composition
In addition to the core programs, an operating system needs other system programs and applications to be practical. Most of the system programs commonly used in the Linux system are software developed by the American Free Software Foundation (Free Software Foundation), and there are many organizations or individuals who develop applications for Linux. Most of these programs are free software, and anyone can obtain them on the Internet for free. However, it is very inconvenient to obtain these programs and install them one by one, so some companies or groups will collect and integrate the programs on Linux and combine the "core-system programs-applications" to form a complete operating system, so that ordinary users can easily install the whole system. This is the so-called "installation kit" (distribution). The Linux system we generally talk about is for these installation packages. It is the same Linux system, but it is divided into different installation packages integrated by different companies and organizations. this is why people often see so many "kinds" of Linux on the Internet.
