In Linux, a background service that runs at boot and provides services to applications is called a ______.

• A. User-Space Application
• B. Daemon That Runs in Foreground
• C. Daemon That Runs in Background, Not Interactive
• D. Kernel Module

Answer: (C)

Daemons are background services in Linux. They start at boot (via the init system) and run without a controlling terminal, providing services to applications and the operating system. This non-interactive, autonomous operation is what lets them run continuously and serve other programs without requiring user input. A user-space application is just any program running in user space and isn’t necessarily started at boot or designed to run detached in the background as a service. A daemon that runs in the foreground would still be tied to a terminal and require interaction, which isn’t typical of daemons. A kernel module lives in kernel space and provides low-level functionality to the kernel, not user applications as a service.
