This article mainly introduces how many kinds of computer systems, the text is very detailed, with a certain reference value, interested friends must read!

There are seven mainstream computer systems, namely: pure DOS system (such as C-DOS, M-DOS), Windows series operating system, LINUX system (such as CentOS, Ubuntu), UNIX operating system, Mac OS operating system, embedded system, Google Chrome OS.

There are several types of computer systems:

1. Pure DOS system:

Including C-DOS, M-DOS, S-DOS, MS-DOS, etc.

2. Windows system

Including Win10, WIN7, WIN8, XP, WIN95, WIN98, WIN2000 and so on

Features:

(1) Intuitive and efficient object-oriented graphical user interface, easy to learn and use

(2) Uniform, friendly and beautiful user interface

(3) Rich device-independent graphical operations

(4) Multitasking operating environment

3. LINUX system

Red Hat, Red Flag, CentOS, Ubuntu, etc.

Features:

Linux has two basic ideas: first, everything is a file; second, every software has a definite purpose.

Linux is a free operating system, users can get it free of charge through the network or other channels, and can modify its source code at will.

Fully compatible with POSIX 1.0 standard

(4) Multi-user, multi-task operating environment; support multiple platforms

UNIX operating system

Including AIX, HP-UX, Solaris, IRIX, Xenix, etc.

Features:

UNIX is a multi-user, multi-task, time-sharing operating system.

UNIX system structure can be divided into three parts: operating system kernel, system call, application program

UNIX systems are mostly written in C.

UNIX provides a rich, carefully chosen set of system calls.

UNIX provides a powerful programmable Shell language as a user interface.

UNIX system adopts tree directory structure

UNIX system adopts the memory management mechanism of process exchange and the storage mode of requesting page transfer

UNIX systems provide multiple communication mechanisms

5. Mac OS operating system

Features:

Full-screen mode is the most important function in the new operating system. All applications can run in full-screen mode.

Mission Control integrates Dock and Control Panel, and can view various applications in window and full-screen mode.

(3) The Quick Launch Panel works exactly the same way as the iPad (8) It displays all apps installed on the computer in an iPad-like user interface and manages them through the App Store, where users can slide the mouse to switch between multiple app icon interfaces.

Mac App Store works exactly the same way as iOS App Store, they have the same navigation bar and management

6. Embedded systems

Embedded systems consist of hardware and software. It is a device that can operate independently. Its software content only includes the software running environment and its operating system. Hardware content includes signal processor, memory, communication module, etc. Compared with ordinary computer processing system, embedded system has great difference, it can't realize large capacity storage function, because there is no matching large capacity medium, most of the storage media used are E-PROM, EEPROM DENG, etc. The software part takes API programming interface as the core of development platform.

7、Google Chrome OS

Chrome OS is a PC-based operating system developed by Google. Google Chrome OS is an open source operating system based on Linux. Google said on its official blog that initially, the operating system will be targeted at netbooks, compact and low-cost computers. This open source software will be named Chrome OS, Google on December 7, 2010 (Beijing time on December 8 at 2:30) held in the United States Chrome-related product launch conference, the conference officially released Chrome Web store and Chrome OS.

The kernel is the most basic component of the operating system, and its structure usually has a certain degree of influence on the external characteristics of the operating system and applications.
