Course Introduction：To create a ZIP file, right-click the file or folder in Windows, select Send to > Compressed (ZIP) folder, and the system will generate the ZIP file of the same name. If you need to compress multiple files, hold down the Ctrl key to select multiple or box to select files, and then package them through "Send to" > "Compressed (ZIP) folder". After compression, you can right-click on the ZIP file and select "Rename" to modify the file name for easy identification. However, it should be noted that Windows' own compression tools do not support RAR or 7Z format, cannot set password protection, and cannot adjust the compression level. If you need these functions, you should use third-party software such as WinRAR and 7-Zip.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
