A mobile operating system (or mobile OS) is an operating system for smartphones, tablets, personal digital assistants (PDAs), or other mobile devices. While computers such as typical laptops are mobile, the operating systems usually used on them are not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This distinction is becoming blurred in some newer operating systems that are hybrids made for both uses. So-called mobile operating systems, or even only smartphones running them, now represent most (web) use (on weekends and averaged for whole weeks).

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, Global Positioning System (GPS) mobile navigation, camera, video camera, speech recognition, voice recorder, music player, near field communication, and infrared blaster.

Mobile devices with mobile communications abilities (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]

The main four smartphone operating systems compared. When choosing a laptop or PC, your decision is essentially between Windows or Mac OS X. Choosing between the myriad smartphones is trickier. Take a look at Macworld's: iPhone vs Android.

• 
  Android OS (Google Inc.)
  
• 
  Bada (Samsung Electronics)
  
• 
  BlackBerry OS (Research In Motion)
  
• 
  iPhone OS / iOS (Apple)
  
• 
  MeeGo OS or Symbian (Nokia and Intel)
  
• 
  Palm OS (Garnet OS or Web 0S)
  
• 
  Windows 10 Mobile (Windows Phone 7)
  

Mobile and computer operating systems have been developed in different ways and for different uses. Computer OS products are older and more familiar to larger groups of users. Through the last 20 or 30 years, the simple idea of a computer operating system has been continually built on and improved. Through this time, Microsoft Windows and Apple's Mac OS have emerged as the two dominant operating system designs. The latests versions being: PC – Windows 10 and MAC – Mac OS X Mavericks 10.9 and 10.12 Sierra. There have also been some open-source operating systems designed for traditional computers as alternatives to Microsoft or Apple licensed operating systems. These include Linux, FreeBSD, OpenBSD and GNU.

There are a lot of details involved in computer OS design, but one prominent fact is that computer operating systems were not really designed for mobile use over wireless networks. Instead, they evolved, and were understood, as part of a wired system, most commonly, as parts of a single physical machine. As such, developers and engineers focused on a lot of technical specifics related to items like boot protocols, program threads, multiple process handling, CPU operation, and other elements of the traditional OS.

The mobile operating system is a newer concept. In many ways, the mobile OS has built on what the computer OS has accomplished. In fact, many modern developers working with mobile operating systems tend to take the traditional elements of computer operating systems largely for granted as they focus on newer issues like responsive design, consistent network access, and other elements of providing software applications used across diverse wireless environments.
