I heard about type of communication where people are making their own language and talking with each other in that way so no one could understand them. Another way of communication is internet. Internet is the most famous type of communication in the world. There are tons of social sites where you can communicate with people all over the world, Example Facebook. I personally use internet and phone to communicate with my friends. I use phone to communicate with friends that are living in Armenia and I use internet to communicate with friends that are living in another country.
