云计算基础知识答案大全(云计算基础知识100条)

The correct statement about cloud computing is ()
A. Cloud computing is distributed computing and parallelism Computing, utility computing, network storage, virtualization, load balancing and other traditional computer and network technology development and integration products.
B. Cloud computing is an emerging shared infrastructure.
C. Cloud computing connects huge system pools together to provide various IT services.
D. Cloud computing is centered on intelligence.
Correct answer: ABC

[Answer]: A
This question tests common sense in science and technology.
Cloud computing is a pay-per-use model that provides available, convenient, on-demand network access into a configurable shared pool of computing resources (resources include networks, servers, storage, applications software service).
Item A is wrong. Cloud refers to the network and the Internet, not fuzzy algorithms. Fuzzy algorithms are derived from fuzzy mathematics, which is a mathematical theory and method for studying and processing fuzziness phenomena.
Item B is correct. Cloud is a metaphor for network and Internet. In the past, cloud was often used to represent telecommunications networks in diagrams, and later it was also used to represent the abstraction of the Internet and underlying infrastructure.
Item C is correct. Cloud computing can achieve 10 trillion operations per second. With such powerful computing power, it can simulate nuclear explosions, predict climate change and market development trends.
Item D is correct. Cloud computing is an Internet-based increase, use, and interaction model of related services, usually involving the provision of dynamically scalable and often virtualized resources over the Internet.
This question is a multiple-choice question, so the correct answer is A.

Basic concepts of cloud computing:

Cloud computing is a method of providing and using computing resources on demand through the network Technology and service model.

Expand knowledge:

Cloud computing is a distributed computing technology that decomposes huge computing processing programs into countless small programs through the network, and then delivers them to multiple servers The system consists of processing and analyzing, and finally returns the results to the user. The goal of cloud computing is to provide computing, services and applications to people as a public facility, allowing people to use computer resources like water, electricity, gas and telephones.

Cloud computing has three main service forms. The first is infrastructure as a service, which provides virtualized hardware resources, such as servers, storage, networks, etc. The second is platform as a service, which provides the software environment and tools needed to develop, test, deploy and run applications. The third type is software as a service, which provides cloud-based applications such as email, office software, games, etc.

Cloud computing can be realized through "public cloud", that is, cloud service providers provide cloud computing services to users through public networks. Users share the same set of infrastructure resources and use them according to their usage. Pay as you go. You can also use a "private cloud", which is a cloud computing environment that is established and managed by the organization itself and is exclusive to the organization. Users enjoy dedicated infrastructure resources, improving security and control.

Characteristics of cloud computing:

1. Ultra-large scale: Cloud computing can utilize computing resources worldwide to form powerful computing capabilities.

2. Elastic scaling: Cloud computing can dynamically increase or decrease resources according to user needs, enabling pay-as-you-go.

3. High reliability: Cloud computing can ensure service availability and data security through multiple backup and fault-tolerant mechanisms.

4. Low cost: Cloud computing can reduce users’ costs in hardware, software, maintenance and management, and improve resource utilization.

5. Ease of use: Cloud computing can provide a simple and easy-to-use interface, so that users do not need to care about the underlying technical details and only need to focus on their own business logic.
