Detailed explanation-1: -The code for managing all this hardware – all the shared resources, as well as process scheduling and memory management – is located in main memory and belongs to the oper-ating system. This part of the main memory is what is commonly referred to as kernel space.
Detailed explanation-2: -Kernel space is the area of system memory reserved for the kernel. It is where the kernel runs and executes kernel mode instructions. Kernel mode is the CPU execution mode of the kernel, which runs in a privileged, root-access mode.
Detailed explanation-3: -All of kernel memory and user process memory is stored in physical memory in the computer (or perhaps on disk if data has been swapped from memory).
Detailed explanation-4: -The kernel is a computer program at the core of a computer’s operating system and generally has complete control over everything in the system. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components.
Detailed explanation-5: -It is one of types of kernel where all operating system services operate in kernel space. It has dependencies between systems components.
