Input and output, or I/O is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.
What is input and output operation?
ABSTRACT. Input-output (I/O) systems transfer information between computer main memory and the outside world. An I/O system is composed of I/O devices (peripherals), I/O control units, and software to carry out the I/O transaction(s) through a sequence of I/O operations.
What is input vs output?
An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.
What is output operation?
The stream flowing from an input device like a keyboard to the main memory, it is called the Input Operation. On the other hand, streams that flow from the main memory to an output device like a screen is called an Output Operation.
Puas yog ib qho kev khiav hauj lwm qhov kev tawm tswv yim lossis cov zis?
Kev khiav hauj lwm qhov system feem ntau yog lub luag haujlwm rau cov tswv yim tso tawm ua haujlwm cuam tshuam thiab kev ua yuam kev yog cov ntsiab lus tseem ceeb ntsig txog kev tawm tswv yim / tawm. Yog li, lub operating system yog lub luag haujlwm los tswj kev cuam tshuam thiab ua yuam kev. Nws tseem yuav tsum tau muab ib qho kev sib txuas ntawm lub cuab yeej thiab so ntawm qhov system.
Dab tsi yog input thiab output piv txwv?
Piv txwv li, keyboard lossis computer nas yog ib qho khoom siv rau lub computer, thaum saib thiab tshuab luam ntawv yog cov khoom siv tawm. Cov cuab yeej siv rau kev sib txuas lus ntawm cov khoos phis tawj, xws li modems thiab network cards, feem ntau ua haujlwm ob qho tib si tawm tswv yim thiab tso tawm.

What is input and output on a graph?
A very useful pictorial representation of a function is the graph. … Each pair of input and output values can be represented on a graph by a single point. The input values are measured along the horizontal axis and the output values along the vertical axis.
What is the role of operating system in computer input output?
The fundamental role of the operating system in computer Input / Output is to manage and organize I/O operations and all I/O devices. The various devices that are connected to the computer need to be controlled and it is a key concern of operating-system designers.
