Summary of "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.
