Can a process go from ready to blocked?

A running process can switch itself into the blocked state, and the OS may ``wake up'' a process by switching from blocked to ready state. Conceptually, this is what happens. But there is a complication: The CPU can only run one process at a time. It can't both run a process and run the OS.

Can a process transition from waiting for an I O operation to the terminated state?

Answer: No. A process waiting for I/O must first transition to the ready queue and then to the running state before it may terminate. They exist entirely within a process, and are scheduled to run within that process's timeslices. The OS is aware of kernel-level threads.
