However, any Windows application can perform the role of a daemon, not just a service, and some Windows daemons have the option of running as a normal process.In short, a Daemon is a background process. Daemons can just be normal programs that run in the background, however most are created by starting a process, forking it and exiting the parent. To fork a process means to create an exact copy of it.
What are daemons How is different from normal process?
Daemon (Linux) A process which runs in the background and is not interactive. They have no controlling terminal on their own from the user’s perspective from the desktop. They continue to exist and operate regardless of any user being logged into the server if the computer is on.

The setDaemon() method of the Thread class is used to mark/set a particular thread as either a daemon thread or a user thread.
Why daemon is used in Linux?

What is process and daemon?
Daemons are processes that run unattended. They are constantly in the background and are available at all times. Daemons are usually started when the system starts, and they run until the system stops. A daemon process typically performs system services and is available at all times to more than one task or user.
What is daemon process in Linux?
A daemon is a long-running background process that answers requests for services. The term originated with Unix, but most operating systems use daemons in some form or another. In Unix, the names of daemons conventionally end in “d”. Some examples include inetd , httpd , nfsd , sshd , named , and lpd .
What is the difference between process and service in Linux?
A process is simply an application or a script which can be running in the foreground or the background. Service is a command which allows you start, stop or restart services running in the background.
How does daemon process work?
A daemon is usually created either by a process forking a child process and then immediately exiting, thus causing init to adopt the child process, or by the init process directly launching the daemon.
What is the difference between daemon and demon?

What is a daemon task?
A daemon task is a pattern used when building microservices where a task is deployed onto each instance in a cluster to provide common supporting functionality like logging, monitoring, or backups for the tasks running your application code.
What is daemon in Linux with example?

In Unix, the names of daemons conventionally end in “d”. Some examples include inetd , httpd , nfsd , sshd , named , and lpd .
How do I run a Linux process in the background?

How are Daemons created in Linux?
The process that creates daemons is the initialization (called init) process by forking its own process to create new ones. Done this way, the init process is the outright parent process. There is another way to spawn a daemon and that is for another process to fork a child process and then die (a term often used in place of exit ).
What is the difference between process and Daemon?
It is said that a daemon has no controlling terminal. A process is a running program. At a particular instant of time, it can be either running, sleeping, or zombie (a process that completed its task, but waiting for its parent process to accept the return value). In Linux, there are three types of processes: interactive, batch and daemon.
Do daemons need a person to start them up?
Daemons do not need a person to start them up. We know that a daemon is a computer program that runs as a background process, rather than being under the direct control of an interactive user.

To identify a daemon, look for a process that ends with the letter d. It’s a general Linux rule that the names of daemons end this way. There are many ways to catch a glimpse of a running daemon. They can be seen in process listings through ps , top, or htop.
