在操作系统中,Kernel Mode和User Mode是两种不同的运行级别,它们在系统安全和稳定性方面扮演着关键角色。Kernel Mode是操作系统内核运行的模式,具有对硬件的完全访问权限,因此在这种模式下运行的程序可以执行特权指令,直接与硬件交互。然而,这也意味着任何在Kernel Mode下运行的程序如果出现错误,都可能导致系统崩溃,如Kernel Panic。相比之下,User Mode限制了程序对硬件的访问,提供了更高的安全性和稳定性,因为即使User Mode下的程序崩溃,也不会影响到整个系统。了解这两种模式的区别和它们在操作系统中的具体应用,对于理解系统安全和性能优化至关重要。
