There are many ways of communication nowadays. First of all, we need to know clearly about communication. the basic of it is the interaction between people. Verbal communication is one ways of communication which means face to face. Write and post a letter is another ways of communication but it's not popular now. Most of us use many contact devices such as: smartphones, laptops, watches,... Thanks to these devices we're be able to interact with people who is far from us in the most convenient ways. However, they're being used popularly makes the old ways of communication is write or post letter become backwards. 

In short, I think each of ways of communication has its bebefit, and all of them help us alot in communicating with people.
