They are usually assigned/attached to the 'init' process (PID 1). For the most part, Zombies can only be removed by rebooting the system.
A zombie process is a process that completed execution but still in process table. When a process ends, all of the memory and resources associated with it are deallocated so they can be used by other processes. However, the process's entry in the process table remains. The parent can read the child's exit status by executing the wait system call, at which stage the zombie is removed After the zombie is removed, its process ID and entry in the process table can then be reused. However, if a parent fails to call wait, the zombie will be left in the process table. In some situations this may be desirable, for example if the parent creates another child process it ensures that it will not be allocated the same process ID.

Unix configuration is the process of tailoring a freshly installed version of Unix to your particular environment. Each Unix system may do that differently.
Unix is inherently portable; this means that a program, script, or process may be moved from Unix system to Unix system with little effort or change (hence - portable).
Yes
Any Linux/Unix process that runs in the background is called a 'daemon' process. The word derives from the Greek meaning "worker".
Usually any orphaned process is owned by the 'init' process (process #1)
Are u talking abt the KErnal process? A program under execution is called process. All processes in UNIX are created using the fork() system call. rest of the question not clear.. SiddharthGanguly
BG is a command on Unix and Unix-like operating systems to run a job(process) asynchronously in the background.
In Unix (and Linux) this is known as "forking".
