Single user mode is designed primarily for systems administration. As such, the system will only load minimal drivers and processes necessary for that administration. Most disk partitions will not be loaded unless they are crucial to the administration of the system. Other users are not allowed to log in to the system in this mode.
Multi-user mode is the normal mode of the system, with all resources available to users both locally and via the network.

User mode. Seriously, that's what it's called.

[Shutdown the system]Runlevel 1: Single user modeRunlevel 2: Basic multi user mode without NFSRunlevel 3: Full multi user mode (text based)Runlevel 4: UnusedRunlevel 5: Multi user mode with Graphical User InterfaceRunlevel 6: Reboot SystemRunlevel 3 is the answer.
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...
User mode and Kernel mode
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.
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.
user mode and kernel mode
No. Regardless of what user you are running as, all your tasks are run in user mode. Supervisor mode is reserved for kernel-level processes.
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.
