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。

附录参考答案Unit 1〖Ex. 1〗根据课文内容回答问题(1) A general-purpose computer has four main sections. They are the arithmetic and logic unit (ALU),the control unit, the memory, and the input and output devices, collectively termed I/O. They are interconnected by busses, often made of groups of wires.(2) The control unit is often called a control system or central controller.(3) ●Read the code for the next instruction from the cell indicated by the program counter.●Decode the numerical code for the instruction into a set of commands or signals for each of the other systems.●Increment the program counter so it points to the next instruction.●Read whatever data the instruction requires from cells in memory, or perhaps from an input device. The location of this required data is typically stored within the instruction code.●Provide the necessary data to an ALU or register.●If the instruction requires an ALU or specialized hardware to complete, instruct the hardware to perform the requested operation.●Write the result from the ALU back to a memory location or to a register or perhaps an output device.●Jump back to the first step.(4) The two classes of operations ALU is capable of performing are arithmetic and logic.(5) Logic operations involve Boolean logic: AND, OR, XOR and NOT.(6) A computer's memory can be viewed as a list of cells into which numbers can be placed or read. Each cell has a numbered "address" and can store a single number.(7) The two principal varieties of computer main memory are random access memory or RAM andread-only memory or ROM.(8) In a PC, the specialized program called the BIOS orchestrates loading the computer's operating system from the hard disk drive into RAM whenever the computer is turned on or reset.(9) Software that is stored in ROM is often called firmware because it is notionally more like hardwarethan software.185(10) I/O is the means by which a computer receives information from the outside world and sendsresults back.〖Ex. 2〗根据下面的英文解释,写出相应的英文词汇(1) input (2) microprocessor (3) program (4) bus (5) hardware (6) memory (7) output (8) cell(9) register (10) address〖Ex. 3〗把下列句子翻译为中文(1) 他进城的目的是买一台新计算机。
