Feedback and Channel

There are two types of feedback; positive and negative. We've all received both and I'd be the first to say I would rather it be positive because I don't take negativity well. If you say something that ticks somebody off then they'll probably not be very nice to you for awhile or they may even say some mean things behind your back. On a lighter note, if you give someone a compliment then you'll probably receive a smile or a thank you back.
The channel in communication is how a message gets from the receiver to the sender. So a channel could be through the t.v., radio, facial expressions, gestures or any other way messages are given from one person to another.
