进程和内核线程之间的区别

1.流程：
进程是执行程序的活动。流程分为两种类型：用户流程和系统流程。过程控制块控制过程的操作。

2.内核线程：
内核线程是一种线程的类型，其中进程的线程在内核级别进行管理。内核线程是由操作系统安排的(内核模式)。

进程和内核线程之间的区别：

PROCESS	KERNEL THREAD
Process is a program being executed.	Kernel thread is the thread managed at kernel level.
It is high overhead.	It is medium overhead.
There is no sharing between processes.	Kernel threads share address space.
Process is scheduled by operating system using process table.	Kernel thread is scheduled by operating system using thread table.
It is heavy weight activity.	It is light weight as compared to process.
It can be suspended.	It can not be suspended.
Suspension of a process does not affect other processes.	Suspension of kernel thread leads to all the threads stop running.
Its types are – user process and system process.	Its types are – kernel level single thread and kernel level multi thread.
