In Unix and Unix-like operating systems (and, to some extent, Windows), as well as certain programming language interfaces, the standard streams are preconnected input and output channels between a computer program and its environment (typically a text terminal) when it begins execution. The three I/O connections are called standard input (stdin), standard output (stdout) and standard error (stderr).
