What are the advantages of using cloud computing?答案：Cloud computing offers several advantages, including:- Cost savings: Companies can reduce their infrastructure costs by using cloud services instead of maintaining their own hardware.- Scalability: Cloud services can easily scale up or down based on demand, allowing businesses to only pay for what they need.- Flexibility: Users can access cloud services from anywhere with an internet connection, enabling remote work and collaboration.- Disaster recovery: Cloud providers often have backup systems in place, ensuring data can be recovered in case of a disaster.- Automatic updates: Cloud services are typically updated regularly by the provider, ensuring users have access to the latest features and security patches.2. Explain the difference between HTTP and HTTPS.答案：HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting data over the internet. It is not secure, meaning that the data being transmitted can be intercepted and read by anyone. HTTPS (Hypertext Transfer Protocol Secure), on the other hand, is a secure version of HTTP. It uses encryption to ensure that data is encrypted before transmission, making it much more difficult for hackers to intercept and read. HTTPS is commonly used for secure online transactions, such as submitting credit card information or personal details.四、编程题请编写一个Python程序，实现计算圆的面积和周长的功能。

On the other hand, an interpreter translates and executes the source code line by line. Python and Ruby are examples of languages that use interpreters.2. Object-oriented programming (OOP) is a programming paradigm that organizes data and functions into reusable objects. It focuses on the concept of classes and objects, allowing for code reuse and encapsulation. An example of a programming language that uses OOP is Java, where objects are instances of classes and can interact with each other through methods and attributes.3. The client-server model is a distributed computing architecture wherea server provides services or resources to multiple clients. The clients request and receive these resources through the network. An example of a commonly used protocol within this model is the Hypertext Transfer Protocol (HTTP), which is used for communication between web browsers (clients) and web servers.四、论述题Artificial intelligence (AI) has had a significant impact on various industries. In healthcare, AI is being used for diagnoses and treatments, analyzing medical images, and personalized medicine. For example, AI-powered algorithms can help detect diseases like cancer at an early stage, leading to better treatment outcomes. In finance, AI is utilized for fraud detection, algorithmic trading, and customer service. AI algorithms can analyze large amounts of financial data to identify patterns and make accurate predictions. In transportation, AI is being employed for autonomous vehicles, traffic management, and logistics optimization. Self-driving cars, for instance, use AI algorithms to navigate and make decisions on the road.The implementation of AI in these industries brings about many benefits, such as increased efficiency, improved accuracy, and cost savings. AI systems can process and analyze vast amounts of data much faster than humans, leading to faster and more accurate results. However, there are also challenges to consider. Privacy and security concerns arise as AI systems handle sensitive information. There is also the worry of job displacement, as AI automation may replace certain human tasks. Additionally, ethical considerations need to be addressed, such as bias in algorithms and the potential for AI to be used for malicious purposes.Overall, the impact of AI on various industries is undeniable. It has the potential to revolutionize healthcare, finance, transportation, and many other sectors. However, careful implementation and regulation are necessary to ensure its responsible and beneficial use.。

The process of testing software by executing it is called ___________.答案: debugging4. Java is an object-_____________ programming language.答案: oriented5. DNS stands for Domain Name ___________.答案: System3. 简答题1. What is the difference between TCP and UDP?答案: TCP (Transmission Control Protocol) is a connection-oriented protocol, which means it establishes a connection between the sender and receiver before transferring data. It ensures that all packets are received in the correct order and provides error checking. UDP (User Datagram Protocol), on the other hand, is a connectionless protocol that does not establish a direct connection before transmitting data. It does not guarantee packet delivery or order but is faster and more efficient for time-sensitive applications.2. What is the purpose of an operating system?答案: An operating system (OS) is a software that manages computer hardware and software resources and provides common services forcomputer programs. Its primary purpose is to enable the user to interact with the computer and provide a platform for running applications. It manages memory, file systems, input/output devices, and multitasking. The OS also handles system security and resource allocation to ensure optimal performance.4. 解答题请参考下文并给出自己的解答。

resist the yearningYet pretending you have never been in my heart. The furthest distance in the worldIs not struggling against the tidesBut using one's indifferent heartTo dig an uncrossable riverFor the one who loves you.倚窗远眺，目光目光尽处必有一座山，那影影绰绰的黛绿色的影，是春天的颜色。
