Tell us more about computer operating systems

In the following narrative about computer operating systems, it is incorrect that ( ) a operating system is a system software.

b The tethering system is only responsible for managing the internal memory and not the external memory.

C Unix is an operating system.

d The computer's hardware resources, such as processor and memory, are also managed by the operating system.

Correct answer: B

In the following description of the computer operation system, it is correct that ( ) a, the operating system belongs to the system software.

b. The operating system is only responsible for managing the internal memory, not the external memory.

c. From the user's point of view, the operating system is the interface between the user and the computer.

d. The computer's processing machine, memory and other hardware resources are also managed by the operating system.

Correct answer: ACD

The computer operating system is as follows:

The basic examination of computer science majors is the principle of computer group elimination, operating system, data structure and algorithm, computer network, computer architecture and other aspects.

1. The principle of computer composition.

Principles of computer composition is the most basic course in computer science, which mainly covers the basic components of computer hardware, including processors (CPUs), memory, input and output devices, etc. The exam usually involves knowledge points such as the composition of a computer, how it works, the instruction set, and the functions and working principles of each component.

2. Operating system.

The operating system is a core component of a computer system, which is responsible for managing computer hardware resources, providing user interfaces, and running applications, among other things. The exam usually examines the basic concepts of the operating system, process management, memory management, file system, security, and network keys.

3. Data structure and algorithm.

Data structures and algorithms are a very important direction in computer science, which mainly studies how to store and process data efficiently in computers. Common data structures (e.g., stacks, queues, linked lists, trees, etc.) and their basic operations and algorithms (e.g., lookup, sorting, traversal, etc.) are typically examined.

4. Computer network.

Computer network is an indispensable part of modern computer systems, which covers many aspects such as communication between computers, network topology, network protocols, network security, etc. The exam usually examines the basic concepts of computer networks, network protocols, network topologies, routing algorithms, network security and other related knowledge points.

5. Computer architecture.

Computer architecture is an important branch of computer science, which focuses on the interface between computer hardware and software and their interaction. Exams usually test the basic principles of computer architecture, instruction set architecture, pipelines, superscalar processors, multi-core processors, and other related knowledge points.

The basic computer test has a wide range of knowledge points, which requires students to have a solid theoretical foundation and a wide range of knowledge. In the process of preparing for the exam, it is recommended that students pay attention to the study of theory and practical practice, and at the same time think and practice in combination with practical application scenarios, so as to better grasp the basic knowledge points of computer.
