The operating system
| |
An operating system is a collection of system software that manages a computer's hardware resources, controls the running of other programs, and provides users with an interactive interface. An operating system is a key component of a computer system, responsible for such basic tasks as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating networks, and managing file systems. There are many types of operating systems that can be installed on devices ranging from simple to complex, from embedded operating systems for mobile phones to large operating systems for supercomputers. At present, the popular modern operating systems mainly include Android, BSD, iOS, Linux, Mac OS X, Windows, Windows Phone and Z /OS, etc., except for a few operating systems such as Windows and Z /OS, most operating systems are Unix-like operating systems. |
