Mac is Apple's personal consumption computer starting with Macintosh from 1984, such as iMac, Mac mini, Macbook Air, Macbook Pro, Mac Pro and other computers. Using an independent Mac OS system, the latest OS X series is developed based on the NeXT system and does not support compatibility. It is a complete and independent ecosystem. Mac system is a special system for MAC, and it can't be installed on ordinary PC in general. Apple not only produces most of the hardware of Mac, but also develops its own operating system. The interface of OS X operating system is very unique, highlighting vivid icons and man-machine dialogue (the graphical man-machine dialogue interface originally came from Palo Alto Research Center of Xerox, and Apple developed its own graphical interface based on its achievements, which was later borrowed by Microsoft Windows and widely used in Windows). Apple can produce computers according to its own technical standards and independently develop the corresponding operating system, which shows that its technology and strength are extraordinary. For example, Apple, like a combination of Dell and Microsoft, is "both talented and beautiful" in software and hardware.
Linux is a Unix-like operating system, which can be used and distributed for free. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX. It can run major UNIX tools, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design idea of Unix and is a multi-user network operating system with stable performance. Linux operating system was born in 199 1 year1year 10/0/0/5 (this is the first official announcement time). There are many different versions of Linux, but they all use the Linux kernel. Linux can be installed on various computer hardware devices, such as mobile phones, tablets, routers, video game consoles, desktop computers, mainframes and supercomputers. Strictly speaking, the word Linux itself only means Linux kernel, but in fact, people have become accustomed to using Linux to describe the entire operating system based on Linux kernel, and using GNU engineering tools and databases.
