Contents of all process-centric registers
What is the impact of a more complex OS and PCB on the context switch?
It increases the context switch time
What information is stored in the accounting information component of the PCB?
CPU used, clock time elapsed since start, and time limits
What is the primary function of the process scheduler?
Selecting the next process for execution on the CPU core
What type of queue holds processes that are waiting for an event to occur?
Wait queue
What is the term for the process of saving the state of the old process and loading the saved state for the new process?

What is the purpose of a Process Identifier (PID)?
To identify and manage processes
What is the result of a process creating several new processes via the create-process system call?
A tree of processes
