Supervising mode is what system kernel runs in.
It has unrestricted access to hardware, processor, memory and everything else.
User mode is managed by supervisor mode, so programs can't crash other programs deliberately by writing over their memory.
User mode programs communicate with hardware and kernel itself by system calls.

Difference between Kernel mode and User mode in Operating System?
bt.o is the kernel mode driver. When you insmod bt.o you are inserting it into the kernel, where it can cause bad things to happen if it screws up. btduser is the user mode driver. It runs as an application in user space, where usually the worse thing that can happen is a segfault. You don't have to insmod anything for user mode. You just run the application.
What is the configuration required for single and multi users in Unix?
It is isn't a configuration difference to go between single user and multi-user modes in Unix. You use a different 'run' level for that. The 'init' levels can determine whether you are operating in a single user mode or a multiple user mode. Single user mode is usually reserved for system administration.
What is the difference between bridge mode and router mode on an ADSL router?
The basis difference between bridge and router mode in a Modem is to identify where does the user creditials are stored. In router mode, they are stored in the modem/router itself. In Bridge mode, creditials are stored on a pc and you would need to click on connection icon / connection to establish the connection KK@Melbourne
What is the difference between the kernel and the user?
Kernel mode is considered a 'privileged' mode, meaning that code executing in that mode can have access to any part of the system, memory, devices, etc. There are no limitations on what it can do. User mode only allows certain operations. Anything requiring any amount of privileged must request the kernel to do things on their behalf. User mode is not a privileged mode and is therefore restrictive in terms of accessing memory, devices, etc.
What is user mode?
The user mode is :a mode that prvides an interface between the application and the OS and only has access to the hardware resources through rhe code running in kernel mode .Type your answer here...

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.
What is the difference between hibernate and switch user?
The Hibernate mode saves your open documents and running applications to your hard disk and shuts down the computer. Switch user closes all the programs and directs you to the other account.

How does the distinction between monitor mode and user mode function as form of protection system?
The distinction between kernel mode and user mode provides a rudimentary form of protection in the following manner: Certain instructions could be executed only when the CPU is in kernel mode. Similarly, hardware devices could be accessed only when the program is executing in kernel mode. Control over when interrupts could be enabled or disabled is also possible only when the CPU is in kernel mode. Consequently, the CPU has very limited capability when executing in user mode, thereby enforcing protection of critical resources.
