Which are background processes that provide functionality to the operating system?

• A. Services
• B. Processes
• C. Applications
• D. Tasks

Answer: (A)

Background processes that provide functionality to the operating system are called services. These run without a user interface, often start automatically at boot, and support essential OS features such as networking, printing, and time synchronization. They’re managed by the OS’s service manager (for example, Windows uses the Service Control Manager, Linux uses daemons/systemd) and run in the background to keep the system functioning. A general process is any running program, whether it has a UI or not, so that term is too broad when we're talking about OS-provided functionality. An application is typically something a user runs to interact with directly, usually with a graphical interface. A task is a unit of work or a scheduled job and doesn’t specifically denote an OS-provided background function.
