Disaster Recovery is the planning for and creation of policies and procedures related to the resumption or continuation of an organization's functions following a catastrophic event. The term is most frequently used in relation to failure of networks, but DR preparations also include other business systems and personnel considerations.

Disaster Recovery

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
