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.

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.
