What is a difference between a daemon and a background process?

Background processes are tied to a terminal's job control, while a daemon runs headless. When the terminal is killed or the user is logged out, the process dies. A daemon does not need the user to be logged in.

What is Daemon Process in unix?
The word daemon is a word of Greek derivation meaning "worker". Daemon processes in Unix are background tasks that do things, such as printing, networking, task scheduling, etc.
The Unix and Linux service the runs in the background is known as the?
Any Linux/Unix process that runs in the background is called a 'daemon' process. The word derives from the Greek meaning "worker".
What is daemond in unix?
A daemon, not daemond, is a program or server application that runs in the background, possibly started during the boot process. A daemon is analogous to what is referred to as a 'service' in the Windows world.
What are demonds?
Daemon refers to the background process that handles all the requests for the services provided such as the file transfers and print spooling.
Name for service that runs in the background?
Daemon.
What are the different types of daemons in Linux?
LInux (and Unix) really don't differentiate between different "types" of daemons. A daemon is a background worker service process. It can do many things, such as networking, database,etc.
What is deamon proscess in unix?
A daemon process is a background service, running as a disconnected process. This means it does not have a terminal interface with an output screen or a keyboard. These services run network processes, job scheduling, etc.
What is a server daemon?
A server daemon is a program that runs in the background and provides some sort of service, such as a web server, SSH server, or a database server.
What is a FTP daemon?
A "daemon" is a program that runs in the background without a graphical interface. In Windows parlance, this would be considered a "service". In the context of FTP and other related Internet technologies, a FTP daemon would be the program "service" that runs in the background (for which the term "server" can refer to the machine that runs such network-facing services or the services themselves).
Why are PID numbers useful when you run processes in the background?
Process IDs are useful for backgrounded processes in cases where you need to either bring it into the foreground, send it a signal, or terminate/kill it. The reason for this is it's often not a good idea to identify a process by its program name lest there be multiple instances and you wish to address one of them. Process names are hardly unique, but running process IDs are. Thus when trying to background a process it's a good idea to make note of its PID. Daemons, on the other hand, don't necessarily require you to track its PID, as they are managed by the system's init system. If a daemon is misbehaving or needs management intervention by you, you can, as root, simply ask init, systemd, or whatever your distribution uses to pause or stop the daemon for a moment. Often when changing a daemon's configuration you use your init system to restart the daemon so it runs on the new config. Do not that daemons and even some other background processes are only under the control of root, or even more extremely, the kernel in kernel space, and you might not be able to do anything with them.
How does the daemon avoid getting killed when its parent process dies?
A true daemon process is disconnected from its parent, so it won't receive a kill signal if the parent dies. It becomes an independent entity after startup.
What is a daemon?
1) a daemon is a computer program that runs in the background, rather than under the direct control of a user; they are usually initiated as processes.2) daemons, dæmon, are supernatural beings between mortals and gods (and normally regarded as bad)3) The daemons in the series "His Dark Materials" are souls.
