Difference between kernel mode and user mode?
Kernel ModeIn Kernel mode, the executing code has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system. Crashes in kernel mode are catastrophic; they will halt the entire PC.User ModeIn User mode, the executing code has no ability to directly access hardware or reference memory. Code running in user mode must delegate to system APIs to access hardware or memory. Due to the protection afforded by this sort of isolation, crashes in user mode are always recoverable. Most of the code running on your computer will execute in user mode.
Does the security subsystem operate in kernel mode?
no, it wont operatesin kernel mode, it operates on usermode.
What is the distinction between kernel mode and user mode in relation as a security system?
Code running in kernel mode has unlimited access to hardware and CPU. Code in user mode can't address memory that kernel mode does not allow it to.

Were 19th century railways good?
No, there were frequent catastrophic crashes that people can still remember nowadays.
What are the two modes of the Windows NT 2000 and XP architecture?
The Windows XP Architecture uses both Kernel Mode and User Mode. The kernel mode is the layer of the operating system's code that is responsible for handling such fundamental operating system items as virtual memory and scheduling which applications will run at any given time. User mode is where your actual program runs and is controlled by components of the kernel. For example, the kernel is responsible for allocating the memory that an application uses.
