What's the difference between a Job and a Daemon?
I currently am a bit confused with all the terms Linux has for running software.
Now these new term job has appeared. What is a job?
It's also a process (running software)? Right?
But especially:
What's the difference between a job and a daemon?
They both seem to be background programs with no user interface. So in what do they differ?

A job is any program that you interactively start and that does not detach itself.
The are a couple of commands for job control:
jobs - List all the jobs that are running or suspended.
fg - Bring the job to the foreground.
bg - Send the job to the background.
stop or Ctrl + z - Suspend the job.
kill or Ctrl + c - Terminate the job.When you append " &" at the end of the command it becomes a "background job".
Jobs tend to end at some point.
A daemon is a process that runs detached from your session. So basically something you/we do not have direct control over. It waits for something to react upon (so when an event happens or a condition is met). Daemons tend to end when you stop them or when the system is shutdown. Where you can start them again manually or during booting.
