Users generally know standard streams as input and output channels that handle data coming from an input device, or that write data from the application. The data may be text with any encoding, or [[Binary file|binary data]].
When a program is run as a [[Daemon (computing)|daemon]], its standard error stream is redirected into a log file, typically for error analysis purposes.

Streams may be used to chain applications, meaning that the output stream of one program can be redirected to be the input stream to another application. In many operating systems this is expressed by listing the application names, separated by the vertical bar character, for this reason often called the [[pipeline (Unix)|pipeline]] character. A well-known example is the use of a [[pagination]] application, such as [[more (command)|more]], providing the user control over the display of the output stream on the display.
