A zombie process is one that should have closed, but is still active in the process table. This is usually caused when a parent process that spawned the process has not yet realized that it has completed, or wants to create another process of the same name without using the same process ID.
A zombie process is basically a process that stops responding, to put it in simple terms.
A zombie process in computing is a child process which has terminated but is still listed in the process table having not yet been reaped by its parent process.
The Linux kernel doesn't consider itself a process, therefore it has no process id.
zombie processes are inherited by the 'init' process (PID 1)
Zombie : Child Process Exits before Parent process and Parent does not grab status of child process using wait() or waitpid() system call; Child process is in Zombie state. Orphan : Child process whose parent has been killed and inherited by init process.
A zombie process is a process that has finished running, but is still there.
It isn't. RTLinux is a separate microkernel that runs Linux as a process. The Linux kernel is essentially unmodified.

Linux is a monolithic kernel. Some operating systems with a microkernel use Linux as a process for providing drivers, but this is irrelevant to mainstream Linux.

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.
