At present, bai is widely used in various systems, so it is difficult to unify the classification with a single DU standard.

It can be divided into batch processing system (MVX, DOS/VSE), time-sharing system (WINDOWS, UNIX, XENIX, Mac OS), real-time system (iEMX, VRTX, RTOS,RT Linux) and batch processing system (MVX, DOS/VSE) according to the use environment of the operating system and the zhi handling way.

According to the number of users supported, it 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), etc.

The five types of operating systems are batch operating systems, time-sharing operating systems, real-time operating systems, network operating systems, and distributed operating systems.

CP/M

CP/M was the first microcomputer operating system, with the privilege of commanding hard equipment such as mainframes, memory, drums, tapes, disks, printers, etc. By controlling the programs and data on the bus, the operating system methodically executes people's instructions...
