I/O DEVICES: OUR INTERFACE WITH THE COMPUTER
Data are created in many places and in many ways. Before data can be processed and stored, they must be translated into a form the computer can interpret. For this, we need input devices. Once the data have been processed, they must be translated back into a form that we can understand. For this, we need output devices. These input /output devices, also referred to as peripheral devices, enable communication between us and the computer.
The diversity of computer applications has encouraged manufacturers to develop and market a variety of I/O methods and hardware. Innovative I/O devices are being introduced continuously into the marketplace. For example, voice recognition devices accept data (input) from human speech. Speech synthesizers produce simulated human speech as output.
