Standarditulostus refers to the process of sending output from a computer program or system to a designated standard output stream. This is a fundamental concept in computing, particularly in command-line interfaces and scripting. When a program is executed, it typically generates some form of output, such as text, data, or status messages. By default, this output is directed to the standard output, which is conventionally the user's terminal or console.

This concept is closely related to standard input (stdin) and standard error (stderr). Standard input is where programs receive data, standard output is where they send their primary results, and standard error is used for reporting errors or diagnostic messages. The separation of these streams allows for flexible handling of program execution and data flow.

For example, in a Unix-like environment, commands like `ls` or `echo` send their results to standard output. This output can be viewed directly on the screen, redirected to a file using the `>` operator, or piped to another program using the `|` operator. This redirection capability is a cornerstone of shell scripting, enabling the chaining of commands to perform complex tasks. Understanding standard output is crucial for anyone working with command-line tools, scripting, or inter-process communication. It represents the default and most common destination for a program's generated information.
