What is ULT and KLT?
There are two types of threads, User level threads (ULT) and Kernel level threads (KLT).
What is a kernel process?
The kernel is a thread of execution—just like any other process. However, the kernel runs in a privileged mode. It can see the physical memory of the machine, and it can see all of the physical devices and ports. The virtual machine concept.
What is the difference between user process and server process in Oracle?

- Stopped (T)
- Zombie (Z)
What is a user account running a process?
