What are the behavioral differences between a daemon and a normal process?

Question

I know that daemons run in the background mostly i.e. they require very less interaction from the user.

Wikipedia lists some of the types of daemons that commonly exist:

Answer 1

Not really. A daemon is just a term for a process that runs continuously and usually is not attached to a terminal.

Daemons are not a separate class of processes and they have no special privileges or attributes.

There is a BSD/Linux C function called daemon (man page), but this is just really a simple way to detach your process from its terminal. It is so named because that's what daemons usually do, not the other way around.
