An operating system is a collection of software that provides services for computer programs. In other terms, an operating system is a composition of a kernel and utility programs; the kernel controls the allocation of hardware resources while the utility programs enhance the usefulness of the computer. One simply cannot grasp what an operating system really is without having some fundamental understanding of what a kernel is.
