Operating System ≡ Resource Manager
An operating system is better considered as being in control of its
hardware and software resources.
Better still, because the "controls" are often temporal or external to
the operating system itself,
let's consider the operating system as a resource manager.
An operating system is just another program
running on the available hardware.
Most of the time, the operating system relinquishes control to the
user processes until the hardware again dispatches the control.
