Cell phones, telephones, video phones, computers, e-mail, text messaging, electronic chatting, message boards, blogs, video cameras, audio recordings and other electronic tools and enhancements are the tools of modern mediated communication. For interpersonal to take place there must be a two way immediate or delayed communication.
Some studies have shown that mediated communication has made life better and decreased stress and interpersonal conflicts. In Afghanistan for the first time in history, most members of the armed services have access to real time immediate telephone and video (Skype and others) communication with their loved ones on a scheduled if not regular basis. The quality of the communication is high, despite a lack of touch, smell and physical intimacy in the transaction. Families keep in touch over long distances with phones, texts, e-mail and tools including Skype and Go-to-Meeting.
There is an immediate transactional response in most mediated communication. This communication is said to be synchronous, or at the same time.
Asynchronous communication is a message that is not read, heard or seem at the same time as it is transmitted. A good example is a letter. There is delay or even a lack of response.
Synchronous messages are those that are sent and received simultaneously, instantly from when they are sent and received. Feedback is usually also immediate.
