What operating systems do computers have?

what operating systems are available on your computer。

There are a wide variety of operating systems and it is difficult to classify them by single criteria.
According to the operating system and the operation of the processing method to consider, can be divided into batch processing system (MVX, Dos/vse), time-sharing system (WINDOWS, UNIX, Xenix, Mac OS), the realtime System (IEMX, VRTX, Rtos,rt Linux);
According to the number of supported users, can be divided into single-user (MSDOS, OS/2), multi-user system (UNIX, MVS, Windows);
According to the hardware structure, it can be divided into network operating system (Netware, Windows NT, Os/2 Warp), Distributed System (Amoeba), multimedia system (AMIGA) and so on.
The five main types of operating system are: Batch processing operating system, time-sharing operating system, RTOS, network operating system, distributed operating system.

Zzwu Reprint Description:

The above refers only to the operating system on the microcomputer, not the operating system used on large, medium and small machines. Otherwise there will be more operating systems, such as virtual storage operating systems with VMS previously on the DEC company minicomputer VAX11, and IBM360 mainframe with os/360 operating system, etc.

But even on the microcomputer, the same operating system can have different versions, such as Linux, there are Redhat (Red Hat), SuSE, Debian, Ubuntu, China's red flag, etc. many different versions.

On smartphones, there are also different operating systems, such as Google's Android and Apple's iOS operating system.
