There are many distinct types of input and output devices. Some of the input devices include Barcode readers, NFC readers, microphone, and a digitizer. All are important and play key roles in a computer’s ability to receive information. Some of the output devices are displays, printers and speakers. The output devices are also essential seeing how they allow the device to sed communication to the user.
An NFC, also known as near field communication reader, is an output device that is extremely popular with merchants and business owners. An NFC allows customers to make purchases with contactless payments. With NFC a customer can use their phone or card that has a magnetic chip and make payments to merchants. This is done by using Radio Frequency Identification. “RFID has been used in places for decades for things like scanning items in grocery stores and luggage on baggage claims and tagging cattle.” (Square, 2024).
Popular output devices are monitors, speakers, and printers. Each of these devices allows communication between the user and the device. This communication ranges from visual graphics that appear on the screen to the speakers used for audio calls or listening to music.
