Among the following operating systems, the ones that belong to the Xinchuang operating system are:

To put it bluntly, Xinchuang is a localized operating system and a domestic operating system.

There are many more such as winning bids for Kirin.

Hongqi linux and so on, but it's just a different shell, and the use is similar to redhat, interested in learning Xinchuang, you can look at linux, you should learn this.

Kylin is an open-source server operating system developed by the National University of Defense Technology. This operating system is a major scientific research project of the 863 Program, with the goal of breaking the monopoly of foreign operating systems and developing a set of server operating systems with independent intellectual property rights in China.

It has the following characteristics: high security, high reliability, high availability, cross-platform, Chinese (with strong Chinese processing capabilities).

High security. It meets the requirements of the fourth level of structured protection of the "GB T 20272-2006 Information Security Technology - Operating System Security Technical Requirements", and is currently the operating system with the highest security level certified in China. It has been widely used in many fields such as military industry, finance, electric power, education, large enterprises, etc., escorting China's informatization construction.

High reliability. It is the first to pass the fourth-level structured protection level security certification of the Information Security Product Testing Center of the Ministry of Public Security Chinese and the military B+ level security certification of the Information Security Evaluation Center of the People's Liberation Army, which is currently the operating system with the highest security level in China.

High availability. Support soft and hard RAID, support RAID0, RAID1, RAID5, RAID10 and other modes. It supports network redundancy and provides multi-mode NIC binding functions to meet the network requirements of different scenarios.

Supports full, incremental backup and restoration, and Grub-based backup and restoration. [1]

Cross-platform. It has passed the standard certification of the American Free Organization for Standardization and is compatible with applications on Linux platforms. In line with the POSIX series standards and compatible with Linux targets**, large-scale applications on the Linux platform, such as graphical environment and Oracle database services, can be directly run on the Kylin secure operating system platform, which effectively expands the application scope.

Chinese. Strictly comply with the national standard GB18030-2000 "Expansion of the Basic Set of Chinese Character Encoding Character Set for Information Exchange", reach the highest level of GB18030-2000 detection specification "A+" product standard, with strong Chinese processing capabilities. It provides Chinese fonts that meet relevant national standards, supports printing systems that meet GB18030 standards, and has the function of directly using Chinese truetype fonts for printing.

In the first question, you can barely choose C. The question is a bit unanswered.

The second question is to choose D.

Why is there no option?,It's the computer's operating system.。

To give you a list of the current common computer operating systems, you see if there is an option, there is a DOS class Unix system.

Linux operating system.

Microsoft Windows system.

Apple Mac OS

Don't quite understand what you're asking.

I choose Windows

The operating systems running on early microcomputers only allowed one user to use the computer at a time, which were called single-user microcomputer operating systems, such as CP M, MS-DOS, etc.

Depending on the number of users using the computer at the same time, the operating system can be divided into a single-user operating system and a multi-user operating system. A single-user operating system means that a computer can only be used by one user at the same time, and one user can enjoy all the hardware and software resources of the system alone, while if multiple users are allowed to use the computer at the same time, it is called a multi-user operating system.

In addition, if a user can run multiple applications (each application is called a task) at the same time, such an operating system is called a multitasking operating system. If a user can only run one application at a time, the corresponding operating system is called a single-task operating system.

A personal computer operating system is a single-user operating system whose main feature is to serve a single user at a certain time.

The early DOS operating system was a single-user single-task operating system, Windows 95 was a single-user multi-tasking operating system, Windows XP 7 was a multi-user multi-tasking operating system, and Linux and UNIX were multi-user multi-tasking operating systems.

Computer Operating System is a book published by Wuhan University Press in 2003, and the author is Huang Shuisong. This textbook comprehensively and systematically introduces the basic concepts, principles and implementation methods of modern computer operating systems. The book is divided into 12 chapters, the first of which describes the development of modern operating systems; Chapters 2 through 10 describe the basic principles, concepts, and implementation of operating systems, including interrupt techniques.

Windows is a multi-user, multi-tasking operating system.

c answer, multi-user and multi-task operation can be achieved by switching users.

Belong to the network operating system are: a unix、b. linux、d. windows nt、e. netware。

Windows NT is Microsoft's network operating system, and Microsoft's other network operating systems are as follows: Windows NT Serve, Windows 2000 Server Advance Server.

Netware is an older network operating system, in the early 90s of the 20th century, Novell's Netware and other systems are called network operating systems, and people generally no longer refer to an operating system as a network operating system.

UNIX is a commonly used network operating system, UNIX system versions mainly include: UNIX, Sun, etc. It supports network file system services and provides data and other applications.

Linux is a new type of network operating system, and its biggest feature is that the source is open, and many applications can be obtained for free.

e.g. I guess.

Because everything else seems to be desktop operating systems, right

Windows NT is an operating system for networking, but it is less compatible with some programs.

nt means that this operating system is more focused on network operations.

The operating system and compiler belong to the system software.

Generally speaking, system software includes the operating system and a series of basic tools (such as compiler, database management, memory formatting, file system management, user authentication, driver management, network connection, etc.), which is the part of the software that supports the normal operation of the computer system and realizes user operation.

The system software is generally carried with the purchase of the computer system, and can also be installed separately as needed.

Choose A, C

The operating system is the core of the system software, and the status of the system software is naturally undoubted;

A compiler is a translation program that translates a source program written in a high-level programming language into an equivalent target program expressed in computer assembly language, machine language, or some intermediate language. It can basically be understood as a language processing program, and it also belongs to the category of system software.

Operating system

What does it mean to compile a program? Possibly yes.

Either a,AC to see if this compiler is installed separately or the system comes with。

Hello! Select D, DOS is the abbreviation of Disk Operating System in English, which means "Disk Operating System".

D, I feel that the Internet was not popular in the era of DOS.

It seems to be a network operating system.。。。

The versions of UNIX network operating systems are: AT&T and SCO and other Microsoft network operating systems mainly include: Windows NT Serve, Windows 2000 Server Advance Server, and the latest Windows 2003 Server Advance Server, etc., the workstation system can use any Windows or non-Windows operating system, including personal operating system, Such as Windows 9X, Me XP, etc.

NT is a network operating system launched by Microsoft for workstations, network servers and mainframe computers, and can also be used as a PC operating system.

Netware is a network operating system launched by Novell, do you have to choose one of them?
