The given document "架构简答题(1)(1).docx" outlines the basic architecture of several key technologies, including Nginx, Tomcat, Zabbix, Redis, Memcached, Varnish, Jumpserver, ELK, Jenkins, and GitLab. It also includes some key questions and answers related to HTTP protocol and MIME mechanism. Firstly, it provides information on the Chinese names and port numbers for HTTP and HTTPS protocols. HTTP, which stands for Hypertext Transfer Protocol, uses port 80, while HTTPS, which stands for Hypertext Transfer Protocol Secure, uses port 443. In addition to this, the document covers the different versions of the HTTP protocol, including HTTP 0.9, HTTP 1.0, HTTP 1.1, and HTTP 2.1. The most mainstream versions are HTTP 1.0 and HTTP 1.1. Furthermore, it discusses the MIME (Multipurpose Internet Mail Extensions) mechanism and its advantages. MIME is an extension of the original email protocol that allows for the exchange of different kinds of data files on the Internet. By introducing this mechanism, HTTP can send multimedia information such as videos and audio, thus expanding its capabilities beyond simple HTML support. Finally, the document explains HTML (Hypertext Markup Language) and its document structure, which includes the <html> tag, <head> and <title> tags for title and metadata, and the <body> tag for the main content. HTML is considered an essential programming language for web page creation. Overall, the document serves as a comprehensive overview of various key technologies and concepts related to web architecture, providing insights into their functions and practical applications. It covers a range of topics, from protocol versions to document formatting, and offers valuable information for understanding and implementing these technologies effectively.
