(Unix) On a href="module.php?name=Lexikon&file=search&eid=1&query=time-sharing">time-sharing system, a task executing in foreground is one able to accept input from and return output to the user in contrast to one running in the href="module.php?name=Lexikon&file=search&eid=1&query=background">background. Nowadays this term is primarily associated with href="module.php?name=Lexikon&file=search&eid=1&query=Unix">Unix, but it appears first to have been used in this sense on href="module.php?name=Lexikon&file=search&eid=1&query=OS/360">OS/360. Normally, there is only one foreground task per terminal (or terminal window). Having multiple processes simultaneously reading the keyboard is confusing.
