What is input and output devices explain with example?
An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. For example, as shown in the top half of the image, a keyboard sends electrical signals, which are received as input.
What is input device short answer?
In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, cameras, joysticks, and microphones.
What are the examples of input device?
In computing, an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. Examples of input devices include keyboards, mice, scanners, digital cameras and joysticks.
What are the 2 most common input devices?
The most common input devices are the keyboard, mouse, and touch screen.
What are two categories of output?
There are four different categories of output device: visual, data, print, and sound.
What are two output devices?
Monitors and printers are two of the most commonly used output devices used with a computer.
What are the types of input and output devices?

Is a keyboard an output device?
I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices.
Why scanner is output device?
A computer scanner is a digitizer, which is a type of input device. A scanner is only able to send information to the computer and cannot receive information from the computer like a printer (which is an output device).
Why printer is output device?
A printer is an output device that prints paper documents. This is because modern printers have a high DPI (dots per inch) setting, which allows documents to printed with a very fine resolution. In order to print a document, the electronic data must be sent from the computer to the printer.
Are speakers input or output?
Speakers receive information from computers (think smartphones, laptops, tablets, etc.) and are, therefore, output devices. This information is in the form of digital audio.
What is speaker input and output?
Speakers are one of the most common output devices used with computer systems. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver. This input may be either in analog or digital form.
