What is a Communications Device?

Answer 1

Communication devices are what some disabled people use to communicate, if they can't talk. There are ones that actually talk, like the one used by the scientist Stephen Hawking, who has ALS. There are of course simpler ones, that only speak a word or a sentence, when the person touches a button or uses a motion of the head to indicate which one they want to say.

Cellphones are also a communication device, of course. Any device used to communicate can be called a communication device.

Here is a more IT based answer: A communication device is a physical part that enables one computer to communicate with another.

Answer 2
