Question

Explain any three characteristics of communication.​

Answer 1

Answer:

(1) Two or More Persons:

(2) Exchange of Ideas:

(3) Mutual Understanding:

Explanation:

1. Your first choice when talking about more than one person is "(two) people". "Persons" only makes sense if you mean "individuals"... and as 郭东兴 has pointed out, this is quite uncommon. Persons is an old word, from formal English.
2. Exchange of ideas between two or more persons is communication. Communication is the exchange and flow of information, fact, opinion or ideas from one person to another. It involves a sender transmitting the message or feeling to a receiver.
3. mutual understanding - sympathy of each person for the other. mutual affection. sympathy - a relation of affinity or harmony between people; whatever affects one correspondingly affects the other; "the two of them were in close sympathy"
