Input/output (I/O) scheduling is the method that computer operating systems use to decide in which order I/O operations will be submitted to storage volumes. I/O scheduling is sometimes called disk scheduling .
In computing environments that support the pipes-and-filters model for interprocess communication, a FIFO is another name for a named pipe.. Disk controllers can use the FIFO as a disk scheduling algorithm to determine the order in which to service disk I/O requests, where it is also known by the same FCFS initialism as for CPU scheduling mentioned before.

The scheduler is an operating system module that selects the next jobs to be admitted into the system and the next process to run. Operating systems may feature up to three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler.
CFS is the first implementation of a fair queuing process scheduler widely used in a general-purpose operating system. [ 5 ] The Linux kernel received a patch for CFS in November 2010 for the 2.6.38 kernel that has made the scheduler "fairer" for use on desktops and workstations.
A disk operating system is an operating system component that deals with high-level disk-IO such as providing the abstraction of a file system resident on a disk storage system (made up of hard disks and/or floppy disk drives). Disk Operating System is often abbreviated by the three-letter acronym DOS and used as a suffix for specific operating ...
Windows successfully loaded the device driver for this hardware but cannot find the hardware device. 42: Windows cannot run the driver for this device because there is a duplicate device already running in the system. 43: Windows has stopped this device because it has reported problems. 44: An application or service has shut down this hardware ...
In computer programming, resource management refers to techniques for managing resources (components with limited availability).. Computer programs may manage their own resources [which?] by using features exposed by programming languages (Elder, Jackson & Liblit (2008) is a survey article contrasting different approaches), or may elect to manage them by a host – an operating system or ...
