All computer operating systems in the world

One, the Windows operating system

Microsoft Windows, a set of operating systems developed by Microsoft Corporation in the United States, was launched in 1985,

At first, only the Microsoft-dos simulation environment, the subsequent version of the system due to Microsoft's continuous update upgrade, not only easy to use, but also slowly become the family's favorite operating system.

Windows uses a graphical GUI, which is more user-friendly than the way the previous DOS requires typing instructions.

With the computer hardware and software upgrading, Microsoft's Windows is also constantly upgrading, from the architecture of 16-bit, 32-bit to 64-bit,

System versions from the original Windows 1.0 to the well-known Windows 95, Windows 98, Windows ME, Windows 2000, Windows 2003, Windows XP, Windows

Vistaws Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, and Windows Server Server Enterprise-class operating systems,

Continuously updated, Microsoft has been working on the development and improvement of Windows operating system.

Second, Unix operating system

The UNIX Operating system (Younis) is a powerful multi-user, multitasking operating system that supports a variety of processor architectures,

According to the operating system classification, belongs to the time-sharing operating system, the earliest by Kenthompson, Dennis Ritchie and Douglas McIlroy in 1969 at the T Bell Labs development.

At present, its trademark rights are owned by the International Open Standards Organization, only UNIX systems that conform to the single UNIX specification can use the UNIX name, otherwise it can only be called Unix-like (unix-like).

Third, Mac operating system

The Mac system is a graphical operating system based on the Unix kernel, and in general the operating system cannot be installed on a normal PC. Developed by Apple itself.

In addition, crazy rampant computer viruses are almost all for Windows, because the Mac's architecture differs from windows, so it is rarely attacked by viruses.

MAC OSX Operating System interface is very unique, highlighting the image of the icon and man-machine dialogue. Apple not only develops its own system, it also involves the development of hardware.

Four, Linux operating system

Linux is a free-to-use and free-to-propagate Unix-like operating system, a POSIX and Unix-based multiuser, multitasking, multi-threaded and multi-CPU operating system.

It can run major UNIX tools software, applications, and network protocols. It supports 32-bit and 64-bit hardware.

Linux inherits the design idea of Unix as the core of network, and is a stable multi-user network operating system.

The Linux operating system was born on October 5, 1991 (This is the first time the official outward announcement).

There are many different Linux versions of Linux, but they all use the Linux kernel.

Linux can be installed in a variety of computer hardware devices, such as mobile phones, tablets, routers, video game consoles, desktops, mainframes, and supercomputers.

Strictly speaking, the word Linux itself only represents the Linux kernel, but in fact people have become accustomed to using Linux to describe the entire Linux kernel, and use the GNU engineering various tools and databases of the operating system.
