Task Manager is my favorite process management tool for managing apps and process-related information. You can find various applications and processes running on the computer from Task Manager and they are in various states. Some may be in a running(active) state, some may be in a suspended state, some running in the background and some are terminated, etc. In this tutorial on Ourtechroom, I'll walk you through why are apps "suspended" in Windows Task Manager.
In this guide, you will also know about types of processes, what is suspended application is, why the application undergoes suspend state, etc. Some awesome? Let's get started right now.
To laymen, we say suspension means "stopping" something. Suppose you have been suspended for a certain duration from your college then you are not allowed to attend class at college for that specific duration as you have been suspended. In the say way, Operating System suspends processes.
What is the Suspended Process?
Ans: Suspended Process are those process which has turn off temporarily. When a process is temporarily suspended then later on it will restart from exactly the same state where it was stopped. So, the state of those processes must be stored somewhere else on your PC. If a process is in a suspended state then it doesn't consume any of your CPU, memory, and network. Technically speaking many operating systems saves these process(active, terminated, suspended) in table structure called process table, which is the array-like structure for each.
Where to find which applications are suspended in Task Manager?
Ans: The Suspended State of process and application is displayed in Status column in Task Manager.
Can we kill Suspended Process?
Ans: Suspended Process cannot be killed even with admin rights. It throws an access denied error.
Why OS suspended Process and Application?
Various reasons for Suspend Application are:
If you minimize the app and works on other processes and apps then OS may take that Application in Suspended State. And when you maximum it will go to an active state to prevent unnecessary usage of CPU cycles.
Lots of application and process runs when you boot your OS, and all the process are not currently running like Outlook Mail apps. So, this mail will go into a suspended state and as soon as you received mail or use mail then this mail apps will be active.
If process A is using a shared file and some process B is requesting for the same shared file then process B will go into temporarily suspended until process A stops for a certain time frame and then B enters immediately. This is done to prevent deadlock.
If the application waited for an event to happens for a long period of time.
The application undergoes suspension when:
Then the process is running and it can be blocked and the blocked process can go suspended and waiting for an event called Blocked Suspended. This especially occurs if the process was performing IO operation and lack of main memory and moved them backed to secondary memory.
Blocked Suspended process can be unblocked and goes into a ready suspended state and from there it can resume the process.
Process is just created and is in the ready state then it can go to ready suspended state and swapping out of main memory and placed in external storage by scheduler. Will be available for execution whenever it is loaded in the main memory.
