Discussion Question #2 (Chapter 2): What is an operating system? What are two examples of operating systems for smartphones and mobile devices? An operating system is the communication between the hardware and software applications for the computer/ device. Together, they allow the device to properly function. An example of an operating system is a desktop or laptop computer having Windows that controls the hardware. There are many different types of operating systems that are hardware specific, so depending upon what a consumer prefers, will depend on the types of software applications they can use on that device. The two operating systems for mobile devices are iOS and Android. iOS runs the Apple devices - iPhone and iPad, while the Android system is made for Google devices. I have a Samsung Galaxy mobile device that runs on the Android system
