What is this used for in the system process?

It is a very important process of the NT core system, and it is indispensable for 2000 and XP. Many viruses and Trojan horses also call it. Service Host Process is a standard dynamic connection library host processing service.

For services running from a dynamic connection library (DLL), it is a common host process name. The files are located under the Windows System32 folder of the system. At startup, check the location in the registry to build a list of services that need to be loaded.

This will cause multiple to run at the same time. Windows 2000 generally has two SVCHOST processes, one is the RPCSS (Remote Procedure Call) service process, and the other is one shared by many services; In Windows XP, there are generally more than 4 service processes; More in Windows 2003 Server. It is a core process of a system, not a virus process.

However, due to the particularity of the process, viruses will also invade in every possible way. You can check whether a poison is poisoned by looking at the execution path of the process. If you suspect that your computer may be infected by a virus or that the service is abnormal, you can find the abnormality by searching for the file.

Generally, only one program will be found in the C: Windows System32 directory. If you find a program in another directory, it's probably poisoned.

It's an input method.

It was the print spooler (or maybe the stealth trojan) that turned it off in the right-click management service on my computer.

I don't know, I guess it's not a good thing.

It's the system process (I have six. Leave it alone).

is part of the Microsoft Office product suite. It can select user text input programs, and Microsoft Office XP language bars. This is not a pure system program, but if it is terminated, it can lead to unknowable problems.

Print Spooler - If you don't currently have your own printer and don't want to print on this computer, you can find the print spooler in the "Services" section of "Management" in "My Computer" (load the file into memory for printing later. "Find, stop, and disable it."

The main program of the web chat tool. Installed with Windows by default. It displays icons in the system tray for quick access. Its features include web chat, file sharing, and audio conferencing.

svchost itself is only as a service host, and does not implement any service functions, the services that need to be started by svchost are implemented in the form of dynamic link libraries, when installing these services, the executable program of the service points to svchost, and when these services are started, svchost calls the dynamic link library of the corresponding service to start the service.

This is the icon of the input method in XP.

This is for printing, so turn it off when you're not using the printer.

This is a messenger service.

These are all systematic processes.

Programs are stationary, processes are dynamic. A program that does not establish a process cannot be recognized by the operating system as a stand-alone unit. A program can correspond to multiple processes, but a process can only correspond to one program.

When a program is translated as a procedure, a program is a specific set of actions, actions, or actions that must be performed in the same way in order to consistently produce the same result in the same environment (e.g., emergency response procedures). A program is a collection of commands written in a computer language to achieve a specific goal or solve a specific problem. A prescribed means for carrying out an activity or process.

A program is made up of sequences that tell a computer how to accomplish a specific task. Since today's computers cannot yet understand human natural language, they cannot write computer programs in natural language.

The process is also called service!

Process is actually a special type of application in Win2000 XP 2003, which is also a program.

However, there are two biggest differences between it and the average program:

One, boot as the system boots.

Two, it runs completely in the background, and generally we can't see it.

The general program is more straightforward and straightforward, requires human participation to run, and directly displays the interface or results.

If you know what the improvement program room is for, you can turn it off, if you don't know it or don't mess around, it will cause the system to crash the driver's.

What program you are currently running in the program room.

Processes are system-related things that reside in memory.

A process is a running activity of a program on a computer on a certain data collection, the basic unit of resource allocation and scheduling of the system, and the basis of the operating system structure.

Processes are introduced in the operating system in order to enable the concurrent execution of multiple programs. Traditional programs cannot be executed concurrently with other programs, and can only be executed concurrently with other programs (processes) after a process has been created for them.

This is because the concurrently executed program (i.e., process) is executed "stop-and-go", and only after creating a process for it, when it stops, can its field information be saved in its PCB, and then the CPU field can be recovered from the PCB and continue to execute when it is scheduled for execution next time, while the traditional program cannot meet the above requirements.

I may not have a downstairs or upstairs major, but I would like to share my views on the process.

Because I'm learning to code, sometimes when it comes to the problem of **, I once made a joke that I successfully adapted the process into **. As a result, I once tested **, the system was confused, and the files in the memory could not recognize each other, so I could only think that I was unlucky ......to reinstall the system

The real purpose of the process is to put all the fragments into a category, which we call "sets", completely separate what is running here from what is running elsewhere.

If any one of these sets creates problems, this entire set creates problems with the others. So if there is a problem, you can directly terminate the operation of this **set.

The set was later renamed "Processes".

The operating system is a huge system, if you don't distinguish between running modules, there will be a huge mess, and any one of the problems will cause problems in my whole system. It's better to separate and tell me ......... there's a problem with that ** set

1. Process is the basic unit of resource allocation and scheduling, and is the basis of OS structure.

2. A process is a running activity of a program with independent functions about a certain data collection. It can apply for and own system resources, is a dynamic concept, and is an active entity. It is not just the program's **, but also the current activity, represented by the value of the program counter and the contents of the processing register.

3. The reason why the operating system introduced the concept of process:

From a theoretical point of view, it is an abstraction of the process of a running program;

From the perspective of implementation, it is a data structure whose purpose is to clearly describe the internal laws of a dynamic system and effectively manage and schedule the programs that run into the main memory of a computer system.

A process is a running activity of a program on a set of data in a computer, the basic unit of resource allocation and scheduling of the system, and the basis of the operating system structure.

Because the current operating system is multi-task and multi-user, in order to ensure that the resources are not affected by other programs when the program is executed, it is necessary to introduce the concept of process. For example, when you open a document, the document cannot be deleted.

Characteristics of sequential programs: closed and reproducible. However, the sequential execution of the program is inefficient.

Concurrent execution and resource sharing of programs. After the emergence of multi-channel program design, the concurrent execution and resource sharing of programs were realized, which improved the efficiency of the system and the resource utilization of the system, but brought new problems.

The characteristics of the concurrent execution of the program: the closure and reproducibility of the program are destroyed, the activities of the program and the machine execution of the program no longer correspond one-to-one, and there may be a mutual constraint relationship between the concurrent programs.

These characteristics of concurrent procedures: independence, concurrency, dynamics and mutual constraints, reflect the essence of concurrent procedures, and the concept of procedures can no longer reflect the essence of program concurrency to find execution, so people have introduced the concept of process.
