An operating system is software that manages a computer’s hardware while providing application writers a consistent interface to the hardware. Early computers had no operating systems. Many modern microcontrollers have no operating systems. Operating systems are practical only on machines with enough memory and compute cycles to support them, and yet, they have become an indispensable part of personal computers.

An operating system is software that manages a computer’s hardware while providing application writers a consistent interface to the hardware. Early computers had no operating systems. Many modern microcontrollers have no operating systems. Operating systems are practical only on machines with enough memory and compute cycles to support them, and yet, they have become an indispensable part of personal computers.
