Just about every computing device has an operating system—desktops and laptops, enterprise-class server computers, your mobile phone. Even specialty devices like iPods, video game consoles, and television set top boxes run some form of OS.

Which device is not an operating system?

Some real-life examples of embedded systems include transit card readers, refrigerators, microwaves, and simple mobile phones. Other than these, computers that do not require complex tasks, such as multi-task scheduling, file systems, or memory management, do not depend on OS.

What devices use operating systems?

Some examples of operating systems include Apple macOS, Microsoft Windows, Google’s Android OS, Linux Operating System, and Apple iOS. Apple macOS is found on Apple personal computers such as the Apple Macbook, Apple Macbook Pro and Apple Macbook Air.
