Which two parts is the computer system divided into?

1. [Answer]: Answer: C Analysis: A complete computer system is usually composed of two major parts: hardware system and software system. Hardware system refers to the physical equipment that makes up the computer, that is, the physical components composed of mechanical, optical, electrical and porcelain parts with the functions of calculation, control, storage, input and output.

2. The computer system consists of two parts: hardware system and software system. A computer system is a machine system that can accept and store information according to human requirements, automatically process and calculate data, and output result information.

3. The composition of the computer system The computer system consists of two major parts: the hardware system and the software system. Hardware (English name Hardware) is calculatedThe abbreviation of computer hardware (mainland China and Hong Kong terms, Taiwan called: hardware) refers to the general term of various physical devices composed of electronic, mechanical and photoelectric components in the computer system.

4. The computer system consists of two major parts: hardware system and software system. The so-called hardware refers to any mechanical, magnetic, electronic device or component that makes up a computer. Hardware is also known as hard equipment. The hardware part consists of five parts: controller, operator, memory, input device and output device.

5. The complete computer system is divided into two major parts: hardware system and software system. The hardware system includes five major parts: operator, controller, memory, input device and output device; the software system includes system software (computer operating system) and application software.

Classification of Computer Systems

1. The four operating system types are as follows: Windows operating system, Linux operating system, Unix operating system and Mac operating system.Windows operating system Microsoft Windows is an operating system developed by Microsoft in the United States based on the graphical user interface, which is mainly used in computers, smartphones and other devices.

2. The classification of operating systems includes the following server operating systems: common ones include Linux, Windows Server, etc., which are mainly used on the server to provide efficient computing power and a stable system environment.

3. Computer software is generally divided into two categories: system software and application software: system software is various operating systems, such as windows, Linux, UNIX, etc., as well as operating system patches and hardware drivers, which are all system software categories.

4. The mainstream of computer systems is as follows: pure DOS system, including C-DOS, M-DOS, S-DOS, MS-DOS, etc. WINDOWS SYSTEM, INCLUDING WINWINXP, WIN9WIN9WIN2000, ETC. LINUX system, including Red Hat, Red Flag, CentOS, Ubuntu, etc.

5. The five types of operating systems are as follows: Windows operating system; UNIX operating system; linux operating system; mac operating system; embedded operating system.

What are the three parts of the morphology of the system

What is a system: an organic whole with specific functions composed of several elements or parts that are interconnected, interact, interdependent and mutually constrained, called a system.

Supporting software includes interface software, tool software, environmental database, etc. It can support the environment of the machine and provide software development tools.

The communication system is roughly composed of three parts: the transmitter (sending source and sending device), the channel receiving device (the receiving device), and the noise source. The source is the source of information, and its function is to convert the original signal into the corresponding electrical signal, that is, the baseband signal.

Constitute the basic form of the human body, head, neck, chest, abdomen, limbs, and maintain the posture. The third function of the movement system is protection. Multiple body cavities, cranial cavity, thoracic cavity, abdominal cavity and pelvic cavity are formed by bones, bone connections and skeletal muscles to protect organs.
