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.
