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。

The Internet, then known as ARPANET, wasbrought online in 1969, which initiallyconnected four major computers at universitiesin the southwestern US . The early Internet wasused by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personalcomputers in those days, and anyone who used it, whether a computer professional or an engineeror scientist or librarian, had to learn to use a very complex system.The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.(四) Choose the best answer according to Passage C.（根据上文的内容选择正确的答案。
