- New:
- Description: The process is being created. In this state, the operating system is setting up the process control block (PCB), memory allocation, and other necessary resources.
- Example: When you start a new application, it begins in the new state while the OS sets up its environment.
- Ready:
- Description: The process is prepared to run but is waiting for CPU allocation. It has all the resources it needs except the CPU.
- Example: Multiple processes might be in the ready state, waiting their turn to be executed by the CPU.
- Running:
- Description: The process is currently being executed by the CPU. At this moment, the CPU is actively working on the instructions of this process.
- Example: When the CPU starts executing the instructions of a text editor, the text editor process is in the running state.
- Waiting (or Blocked):
- Description: The process cannot continue executing until some external event occurs (such as an I/O operation completion). It is not ready to use the CPU until this event is resolved.
- Example: If a process needs to read data from a disk, it will move to the waiting state until the disk I/O operation is completed.
- Terminated (or Exit):
- Description: The process has finished its execution. This state means that the process has completed its task and is being removed from the process table.
- Example:When you close an application, the process goes into the terminated state after finishing its execution and cleanup activitie
Process States Explanation: In operating systems, a process is a program in execution. As a process runs, it goes through different states. These states represent the current condition of the process in the system. Let's break down the main process states: 1. New: The process is being created. 2. ReRead more
Process States Explanation:
In operating systems, a process is a program in execution. As a process runs, it goes through different states. These states represent the current condition of the process in the system. Let’s break down the main process states:
1. New: The process is being created.
2. Ready: The process is waiting to be assigned to a processor.
3. Running: The process is currently executing on the processor.
4. Waiting (or Blocked): The process is waiting for some event to occur (like I/O completion).
5. Terminated: The process has finished execution.
Examples:
1. New: When you double-click on an application icon, the operating system creates a new process.
2. Ready: Multiple programs open on your computer, waiting for their turn to use the CPU.
3. Running: The video game you’re currently playing.
4. Waiting: When you click “Save” in a document and wait for it to complete.
5. Terminated: When you close an application, and it finishes its execution.
Now, let’s visualize these states with a diagram:
Explanation of the diagram:
1. A new process starts in the “New” state.
2. It then moves to the “Ready” state, waiting for the CPU.
3. When the scheduler selects it, it goes to the “Running” state.
4. From “Running,” it can:
a) Go back to “Ready” if its time slice expires.
b) Move to “Waiting” if it needs to wait for a resource or event.
c) Proceed to “Terminated” if it completes execution.
5. From “Waiting,” it returns to “Ready” when the waited-for event occurs.
This cycle continues until the process terminates.
