The Subject "Communication" is a vast subject To Put it in Simple Form:

NICE ANSWERS BY MY FRIENDS HERE,,,,FULLY AGREED ,,, JUST WANT TO ADD THAT MONOLOUGE IS ONE WAY COMMUNICATION WHEN YOU GIVE YOUR WORDS AND DO NOT FEEL ANY IMPORTANCE OF LISTENING,,,, DIALOUGE IS TWO WAY COMM. WHEN YOU SPEAK & HEAR FROM OTHER PARTY,,, GOOD LUCK

one- way  communication usually used to inform and persuade customer or people and the maindifference between one-way and two-way communication is the feedback from the receiver (customers) in two way communication the sender want to know if the message has been received accurately for example including a toll free in your advertising , cobone and link in your email to interact with audience  .

Technology changed they way customers communicated with their brands or companies now. For example social media change static approach to interactive , where people can like, dislike, agree or disagree their opionios and products.  on the other hand TVC still one way communication where you introduce your product to customer regardless knowing what they think of that. 

One way communication is a way to share information to others which do not include any revert back from the listeners.

For example : The news telecast on TV on news channels

Two communication is a way to share information to others where feedbacks or reverse questioning is there for the communication held.

For example : A discussion held on TV on news channels with panels of some persons where they can ask counter questions.

Example2: The best example could be the staff meeting where informations is given and staff members are asked to raise questions or to give feedback.

For example: When you design an  Advertisement,  you see the progress of this announcement and at the same time waiting for the reactions of consumers from this announcement 

It's good answers from all and can i add for themmy answer

the one way is indirect comminication with the guest by advertising from your company by news,T.V, Radio etc

the tow way is direct comminication with customer by meeting , interview, e-mail , call

Whether it is a Prospect, Customer, Supplier or your colleague,, both parties have points to make. Therefor it is crucial that listening and talking capabilities are well balanced. You have one mouth and two ears to listen.

all the above answers i agree with them , but can we make it sample answer as below :-

1) One way : as it shows from its name its1 way either from speaker or listner .

2) Two ways : as it shows from its name its2 way , meaning from the both sides who talks either the listner 

                        Or the speakers.

1.One way communication, is like a coin having same image on both the faces, i.e., just to share the information to the targeted group of individuals, but not receiving any feedback or inputs from them..

2. Two way communication is process through which inputs are received and opinions are sought    from the targeted group of individuals.

One way communication, is what happens in college, university etc. Someone talks, someone listens. Main characteristic is the absence of interactivity.

Two way communication, is when someones seeks someone else's input, opinion, reaction etc.

In this kind of communication, interactivity is the main element and also  things as body language or non speaking communication are activated.
