The different states of a process:

• As it runs, a process goes through various phases. Distinct operating systems may have different states. The most typical process states, however, are described here.
• When the process is first created, it is in this state. In the process life cycle, it is the first state.
• Ready-The process is in the ready state and is waiting for the short term scheduler to assign it a processor so it may run. This stage occurs shortly following the process's new state.
• Suspended Ready-The processes that are ready to be resumed are stored in secondary memory. They were initially ready in main memory, but due to a lack of memory, they were forced to be postponed and stored in secondary memory.
• Running-When the processor executes the process instructions, the process is said to be in a running state. This is done after the short-term scheduler assigns the process to the processor.
• Blocked-If a process is waiting for anything to happen, it is in a blocked state. This event could be I/O because I/O events run in main memory and do not require the processor. When the event is finished, the process returns to the ready state.
• Suspended Blocked-This is comparable to ready-to-hang. Processes that are blocked and suspended are stored in secondary memory.
• Terminated-Once the process has completed its execution, it is terminated. The process is removed from main memory and its process control block is also erased when it is terminated.
