What is Kernel


It is the Core of Operating system. Kernel is the center part of layered architecture that manages most basic operations of OS
And processor's
It creates threads for the processor to keep it as busy as possible and coordinates multiple processors to optimize performance. It also synchronizes activities among Executive-level subcomponents, such as I/O Manager and Process Manager, and handles hardware exceptions and other hardware-dependent functions. The kernel works closely with the h/w abstraction layer.
