Android is a software developed by Google, Inc. that functions as an operating system for mobile devices, primarily smartphones and tablets. In addition to serving as an operating system, Android can act as middleware capable of operating on top of other operating systems. It also encompasses a wide range of applications that enhance its functionality. Internationally, Android is a highly used platform and is implemented on several different smartphone models from various manufacturers.
Interestingly, in a generic sense, an android refers to a humanoid robot, a notion deeply embedded in science fiction literature and media.
