In Linux, application services are called ______.

• A. Processes
• B. Daemons
• C. Threads
• D. Services

Answer: (B)

Background services in Linux that run without a user interface are called daemons. A daemon is a kind of program designed to stay running in the background, usually starting at boot or on demand through the system’s init manager (like systemd). These processes detach from any terminal and provide ongoing services such as web serving, remote login, or scheduling tasks. Think of a daemon as the dedicated service-provider in the system. By contrast, a process is any running instance of a program, and a thread is a smaller path of execution inside a process. “Services” is a general way to describe capabilities, but in Linux the specific term for these background, long-running service programs is daemon. For example, programs like sshd or httpd are daemons.
