1 lis 2023 · An input/output device, often known as an IO device, is any hardware that allows a human operator or other systems to interface with a computer. Input/output devices, as the name implies, are capable of delivering data (output) to and receiving data from a computer (input).
If the device's main purpose is to gather information for the computer, then it's an input device. If its main purpose is to let the computer communicate information to the user, then it's an output device.
Input devices converts inputs into digital data which can be processed. For conventional computer systems, such as desktop computers and laptops, the most common input devices are the mouse and the keyboard. There are a wide range of input devices used in more specialist computer systems such as scanners and sensors.
There are input devices that take input from the outside world and convert it into binary information. There's memory to store this information. There's a central processing unit, or CPU, where all the calculations are done. And finally, there are output devices that take information and convert it into physical output.
An output device shows the results of the processing in a way humans can understand. In a general purpose computer system, the main output device is the monitor/screen. Other output devices include projectors, printers, speakers and actuators.
Learning Objectives. Identify the methods by which data is entered into the system unit. Identify how information (the result of processing) is displayed or stored. Compare various input and output devices and determine which ones best fit a specific situation or need.
