An operating system (OS) is a software program that manages the hardware and software resources of a computer. The OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files.

Introduction

---

Modern general-purpose computers, including personal computers and mainframes, have an operating system to run other programs, such as application software. Examples of operating systems for personal computers include Microsoft Windows, Linux, Mac OS (Darwin), and Unix.

The main advantages of an operating system include:

1. Allows multiple programs to run concurrently.
2. Simplifies the programming of application software because the program does not have to manage the hardware. The operating systems manages all hardware and the interaction of software. It also gives the program a high level interface to the hardware and ways of interacting with other programs.

@pbarreto I want to ensure that *my* app will not blow someone's head. Operating systems will crash, not send a high voltage to the patient.
