Device Management Pdf Usb Operating System Overview i o management is a major component of os design and operation. ports, busses, device controllers connect to various devices. device drivers encapsulate device details. There are three basic techniques for implementing the policies of device management (a) dedicated a technique whereby a device is assigned to a single process. (b) shared a technique whereby a device is shared by many processes. Device manager initializes, controls, and drives the physical devices and virtual devices of the system. main classes of devices are char devices and block devices. The process of implementation, operation, and maintenance of a device by an operating system is called device management. when we use computers we will have various devices connected to our system like mouse, keyboard, scanner, printer, and pen drives.

Computing is not interesting without i os device management: the os component that manages hardware devices. Overview i o management is a major component of operating system design and operation. This discipline protects data from access control violations and also protects the system from erroneous use of device controllers that could cause a system crash.
