1.1 What is Linux?
Linux is the core and system call two layers, applications are not considered Linux.
Example question:
Can the Windows operating system be installed on Apple's Macintosh computer (MAC) and does not work?
Answer:
From the above description, we know that the hardware is controlled by the "core", and each operating system has its own core. Before 2006, Apple Computer asked IBM to help develop the hardware (Power CPU), while Apple Computer developed its own operating system (commonly known as Macintosh, MAC) on the hardware architecture. Windows is one of the operating systems developed on the x86 architecture, so there is no way to install Windows on Macintosh hardware.The Windows operating system was originally designed for personal computer x86 architecture hardware, so of course it can only run on x86 personal computers, but it cannot run on different platforms. In other words, each operating system runs on other machines.
Two, the development of Linux
Linux is the bottom core of an operating system and provides core tools. It is a GNU GPL licensed model, so anyone can obtain the source code, not execute this core program, and can modify it. In addition, because Linux refers to the POSIX design specification, it is compatible with the Unix operating system and can also be called a kind of Unix Like.
