Messaging, email and chat

Asynchronous communication allows a user to send a message to someone who may not be online or is required to answer immediately. Email is a good example of this type of communication. It is possible to also leave messages on synchronous communication programs such as Skype and Google Hangout or other chat programs that can be read later. Discussion boards, social networks and forums would also come under this activity.
