A "daemon" is a background process in computing that runs independently of user interaction. It performs tasks such as managing system resources, handling network requests, or scheduling jobs. Daemons are essential for the smooth operation of operating systems like Linux and Unix, where they help automate various functions. In a broader context, the term "daemon" originates from the Greek word "daimon," which refers to a guiding spirit or supernatural being. In literature and mythology, daemons are often depicted as entities that influence human behavior or events, reflecting a dual nature of assistance and mischief.
