Process State

Video Lecture Summary

The video lecture focuses on the concept of process states in process management. It explains that a process, which is a program in execution, can be in several states depending on its current activity. The key states discussed are:

• New State: The process is being created.
• Running State: The process is actively executing instructions.
• Waiting State: The process is waiting for an event to occur, such as the completion of an input/output operation or the reception of a signal.
• Ready State: The process is waiting to be assigned to a processor for execution.
• Terminated State: The process has finished execution.

The lecture also describes how a process transitions between these states:

• After creation, it moves from the New State to the Ready State.
• Once assigned a processor, it enters the Running State.
• If interrupted, it returns to the Ready State.
• If it needs to wait for an event, it goes to the Waiting State and returns to the Ready State once the event occurs.
• Finally, upon completion of execution, it transitions to the Terminated State.

The video includes a diagram illustrating these transitions, emphasizing the cyclical nature of process states.
