Computer devices are controlled and governed by pieces of software called drivers.

Operating system
The device drivers allow the operating system to communicate with peripheral devices.
Drivers are written for many operating systems.
Four of the most critical components controlled by an operating system are: CPU, RAM, Hard Drive and Motherboard.
plug and play devices are automatically detected by the operating system, where as non plug in play devices are not automatically detected by the operating system.
A mobile operating system is an operating system (the most basic instructions to allow a device to load software and control hardware) specifically for mobile devices.
Devices that record precise results require a real-time operating system. This is the same kind of operating system needed for a device hat performs regimented tasks.
The combination of dedicated devices and shared devices those devices are called as vertual devices.
Not all devices are completely "plug and play" on all operating systems. For those devices that your computer's operating system does not automatically recognize it will be necessary to install the driver software for the device. Unfortunately driver software for some devices is not available on every operating system.
