Allows a computer user to easily access the hardware and software of a computer system Components of an OSKernel, Device Drivers, Shell, Services, Utility Programs KernelCore of the OS. Interface between hardware and software. Performs resource and memory management.Device DriversDevice drivers provide specific interfaces between the OS running a computer and hardware.ShellThe shell is an interface for the user. Provides access to kernel interfaces Services (daemons)programs that are usually started when the operating system is loaded and initialized, but they run in the background Utility ProgramsSystem utilities are programs that allow the user to monitor and improve system performance Application softwareprograms that end users run to accomplish tasks.
