Information is input from the keyboard as intelligible data and output to the printer as unrecognizable junk.

Input/output, or I/O, refers to the interfaces that different functional units of a system use to communicate among each other, or to the signals sent through those interfaces. Inputs are the signals received by the unit, and outputs are the signals sent from it. The most common use of the term is for computer I/O devices that are used by a person (or other system) to communicate with a computer. For instance, keyboards and mice are considered input devices and monitors and printers are considered output devices. Notice however that all the previous devices have both input and output, but the perspective is from the computer. Mice and keyboards take physical movement as input and convert it into signals that a computer can understand, whereas printers and monitors take signals that a computer can output and convert them into representations that humans can see or read.

adj. Pertaining to (a) input, output, or both or (b) a device, process, or channel involved in data input, data output, or both.

This term refers to devices that have the capability of transmitting and receiving data in both directions, such as a disk drive or, more generally, a computer.

A generic reference to input and/or output to a computer.

The process of transferring data to and from a computer controlled system using its communication channels, operator interface devices, data acquisition devices, or control interfaces.

Each microprocessor and each computer needs a way to communicate with the outside world in order to get the data needed for its programs and in order to communicate the results of its data manipulations. This is accomplished through I/0 ports and devices.

A general term for devices that communicate with a computer. Input/output is usually abbreviated as I/O.

The data that a program reads or writes. Also, devices to read and write data.

The process of loading data into or copying data from an MCA or computer using a peripheral device, such as a computer, a floppy disk, or a printer.

The process of, or equipment used in, transmitting information to or from the computer.

is a term used in programming and digital circuit design to refer to functions or circuits that dealt specifically with input and/or output functionality of hardware or software.

The analog or digital signals entering or leaving a DCS or other central control or computer system involving communications channels, operator interface devices, and/or data acquisition and control interfaces.

An operation or device that allows input and output.

User interface devices such as keyboards, monitors, terminals, printers - devices that interface people with computers.

The inputs and outputs of a machine. Typically, inputs are from switches, etc., and outputs are to lamps, etc.

Transmitting data between peripherals unit and more centrally located equipment.

Pertaining to either input or output, or both.

An operation, program, or device that enters data into or extracts data from a computer.

This abbreviation refers to any operation in a computer where data is transferred in or out of the computer. I/O may seem like a vague concept, but it...

The two-way transfer of GPS information with another device, such as a nav plotter, autopilot, or another GPS unit.

Communication between a computer and its users, its storage devices, other computers (via a network) or the outside world. The devices the computer uses to do this are called "peripherals". Source: Foldoc: Free On-line Dictionary of Computing

The process of entering information into a system (input) and its subsequent results (output). A hardware device that enables input (for example, a keyboard or card reader) and output (for example, a monitor or printer). Collectively known as I/O.

(a) The values that are passed into a procedure, and which are returned as the results of the operation of a procedure. (b) In general, those aspects of a computer system which involve the transmission of data into the system, and the communication of results back to the outside world. See also Argument/Result, Calling a Procedure.

Pertaining to a device or to a channel that may be involved in an input process, and at a different time, in an ouput process.

The process or devices used to supply input to a computer program and display or sound output.

An electrical interface abbreviated as I/O.

That portion of a computer which interfaces to the external world.

Ports on a reader. Users can connect devices, such as an electronic eye to the input port so that when an object breaks the beam of the electronic eye the reader begins reading. Devices can also be connected to an output part, so that when a tag is read, a conveyor is turned on or a dock door opened.

The different ways that information is put into a system and gotten out of a system. Input can be a trunk, a telephone or a data port on the telephone system. Output can be the same. Output can also be SMDR and AIOD. For computers, I/O devices include the keyboard, mouse, monitor, printer, speakers, etc

Abbreviated I/O. The transfer of data between the computer and its peripheral devices, disk drives, terminals and printers. ... more

In computing, input/output, or I/O, is the collection of interfaces that different functional units (sub-systems) of an information processing system use to communicate with each other, or the signals (information) sent through those interfaces. Inputs are the signals received by the unit, and outputs are the signals sent from it. The term can also be used as part of an action; to "do I/O" is to perform an input or output operation.
