Device drivers are software specific to each input/output (I/O) device that enables the operating system to work without modification over different hardware. [102] [103] Another component of file systems is a dictionary that maps a file's name and metadata to the data block where its contents are stored. [104]
Devices for communication between computers, such as modems and network cards, typically perform both input and output operations. Any interaction with the system by an interactor is an input and the reaction the system responds is called the output. The designation of a device as either input or output depends on perspective.
Unlike the internal bus, the external bus is connected using a bus controller that allows the peripheral system to operate at a different speed from the CPU. [62] Input and output devices are used to receive data from the external world or write data respectively. Common examples include keyboards and mice (input) and displays and printers ...
Devices that provide input or output to the computer are called peripherals. [126] On a typical personal computer, peripherals include input devices like the keyboard and mouse, and output devices such as the display and printer. Hard disk drives, floppy disk drives and optical disc drives serve as both input and output devices.
The operating system is responsible for translating these channel programs before executing them, and for this particular purpose the Input/Output Supervisor (IOS) has a special fast fix function which was designed into the OS Supervisor just for those "fixes" which are of relatively short duration (i.e., significantly shorter than "wall-clock ...
The computer sends data to an output device; examples: monitor, printer, headphones, and speakers; The computer sends and receives data via an input/output device; examples: storage device (such as disk drive, solid-state drive, USB flash drive, memory card and tape drive), modem, router, gateway and network adapter
