What are the important processes in the system that cannot be terminated

3. The fact that all processes go from the execution state to the blocking state cannot be due to the current running process (d

Knowledge points: process management - p v operationThe p operation represents a request for a resource, and the process cannot be allocated a resource, and the process must wait to enter the blocking queue.

The v-operation is an operation to release resources. If you perform the p operation, the current process may enter the semaphore queue and be blocked.

Perform the v operation, and the current process continues to be running.

The meaning of the question is: blocking state, so it can't be the release of some kind of resource

Does running the interrupt handler create a new process, or is it part of an existing process?

Does running the interrupt handler create a new process, or is it part of an existing process? Hello dear, different computers have their own characteristics for interrupt handling, and for the most part, the interrupt handling process is as follows: Turn off the interrupt, enter a state that cannot respond to the interrupt again, and is implemented by the hardware.

Save the breakpoint so that it can be returned to the breakpoint correctly after the interrupt processing is completed. Implemented by hardware. Send the entrance address of the interrupt service program to the PC and turn it to the interrupt service program.

It can be implemented by hardware or software. Protect the field, set the shield word, and open the interrupt, that is, protect the contents of certain registers in the CPU, set the interrupt processing order, allow more advanced interrupt requests to be answered, and implement interrupt nesting. Implemented by software.

Device services, which are actually effective interrupt handling work, are implemented in this segment. Implemented by a software program. Exit the interrupt.

When exiting, it should enter an uninterruptible state, that is, turn off the interrupt, restore the shield, restore the scene, open the interrupt, and interrupt the return. Implemented by software.

There is nothing to close, and Guan Liangsa is too lazy to close them one by one, and he has to look for them one by one.

So be it. Looking at the system idle process, the processor idle process is still relatively large, and it is basically no problem to run it.

You can use the command to enter "msconfig" in the start menu to turn off some useless boot auto-start items ctfmon must be kept) some of your antivirus software can be kept like 360, Rising and so on.

The main thing is to see what program you have started, and then look at the process, and then make a comprehensive judgment. No one knows just by asking like this, and it is not accurate to know.

From the process, you can see the computer resource occupation and the Trojan situation.

Takes up the most CPU or memory, but you think it's useless.

The process from the execution state to the blocking state cannot be due to the current running process (d know the trembling family knowledge: process management --p

v operation. The p operation represents a request for resources, and the process cannot be allocated to the macro for the hole, and the process must wait and enter the blocking queue.

The v operation is the operation to release the source of Zikai's disadvantages.

If you perform the p operation, the current process may enter the semaphore queue and be blocked.

Perform the v operation, and the current process continues to be running.

The meaning of the question is: blocking state, so it can't be the release of some kind of resource

Wake up by waiting for something to happen.

The process under your own username will close your current application when it ends, and the process of the system will either not be finished, or it will end up causing some of the system software you have installed to be unusable, or it will directly lead to the blue screen of death restart, etc.! There are a lot of processes that you can't end, and those are the basic processes of the system!
