Standard output, often abbreviated as stdout, is a communication channel used by computer programs to send data to the display or terminal. It is a fundamental concept in programming and operating systems, allowing users to see the results of commands or the output of applications. In many programming languages, such as Python and C, standard output is typically accessed using specific functions or commands. For example, the print function in Python sends text to the standard output, which is usually the screen. This allows users to interact with programs and view results easily.
