The operating systems were designed to run on desktop and laptop computers. Mobile devices such as phones, tablet computers, and MP3 players are different from desktop and laptop computers, so they run operating systems that are designed specifically for mobile devices. An operating system is the most important software that runs on a computer. It manages the computer's memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language. Without an operating system, a computer is useless. The operating system (OS) allows users to perform the basic functions of a computer. The OS manages all software and peripheral hardware and accesses the central processing unit (CPU) for memory or storage purposes. It also makes it possible for a system to simultaneously run applications. All PCs, laptops, tablets, smartphones, and servers require an OS. Developers may use specific operating systems that are more conducive to programming and application development, while the average employee will likely use a proprietary system for more common, everyday usage. The most common operating systems are Microsoft’s Windows, Apple’s OS X, Linux distributions, and mobile operating systems for smartphones. A PC can be a Linux, Windows, Mac, Chrome variant, or other OS installed on it. A PC is a personal computer. A smartphone can also have different OSs on them and with different levels of security, the same goes for tablets. These are all hardware devices that you are asking a question about, the security will be mostly software related with some extra hardware sometimes. That is like asking a question what tires will last better, a hand wagon, a car, or a semi-truck. All can be secure and all can also be a leaking component for your information and privacy leaving you vulnerable to attack.
