"/"Forward slash, English is forward slash,

"\" Backslash, English is backward slash

1. Origin of both

In most places, / (slash) is used, including Mac/Linux, and URLs. The only thing you need to remember is that Microsoft uses backslash in its operating system to set itself apart.

2. The use of both

Unix uses slash/ as the path separator, while WebThe application was first used on Unix systems, so currently all network addresses use slash/ as a separator. Windows Since the slash / is used as the parameter mark of the DOS command prompt, in order to avoid confusion, the backslash \ is used as the path separator. Therefore, the current file browsers on Windows systems use backslash \ as the path separator. With development, the DOS system has been eliminated, and the command prompt is rarely used. Slashes and backslashes can be interchanged in most cases without impact.
