Kernel mode is often referred to as "supervisor mode" or "privileged mode." These terms highlight the level of access and control the operating system has over hardware and system resources when executing code in this mode. Additionally, "system mode" is another term used to describe the same operational context where the kernel can execute critical tasks and manage resources securely.
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.
