In this article, we will discuss some important thing about process state

• Note 1: A process necessarily goes through a minimum of 4 states.

  1. The minimum number of states through which a process compulsorily goes through is 4.
  2. These states are new states, ready states, run states, and terminate states.
  3. However, if a process also requires the I/O operation, then the minimum number of states is 5.

• Note 2: A single processor can execute only one process at a time.

  1. A single processor can not execute more than one process simultaneously.
  2. If n processors are present in the system, then only n processes can be executed simultaneously.

• Note 3: Which state present in which memory

  1. New State:- Secondary Memory
  2. Ready State:- Main Memory
  3. Running State:- Main Memory
  4. Wait/Block State:- Main Memory
  5. Suspend Wait State:- Secondary Memory
  6. Suspend Ready State:- Secondary Memory
  7. Terminate State:- Not In Memory
