A mobile operating system (or mobile OS) is an operating system for smartphones, tablets, PDAs, or other mobile devices. While computers such as the typical laptop
are mobile, the operating systems usually used on them are not
considered mobile ones as they were originally designed for bigger
stationary desktop computers
that historically did not have or need specific "mobile" features. This
distinction is getting blurred in some newer operating systems that are
hybrids made for both uses.
Mobile operating systems combine features of a personal computer
operating system with other features useful for mobile or handheld use;
usually including, and most of the following considered essential in
modern mobile systems; a touchscreen, cellular, Bluetooth, Wi-Fi, GPS mobile navigation, camera, video camera, speech recognition, voice recorder, music player, near field communication and infrared blaster.
Mobile devices with mobile communications capabilities (e.g.
smartphones) contain two mobile operating systems – the main user-facing
software platform is supplemented by a second low-level proprietary real-time operating system
which operates the radio and other hardware. Research has shown that
these low-level systems may contain a range of security vulnerabilities
permitting malicious base stations to gain high levels of control over the mobile device.[1]
