Distance becomes a non-issue. The great news is that technology and technologic applications continue to proliferate at a stunning rate. This technology application is dependent not only upon computer hardware and software but also on network communication and the internet. Each of these components will be reviewed from a DVC perspective. Microphone - Most computers today are multimedia compatible which means they are equipped with audio capture and playback capacities.
All computers manipulate digital information in their processing functions.
