Synchronous and Asynchronous Communication

  • Direct communication where the communicators are time synchronized. This means that all parties involved in the communication are present at the same time or in other word, face to face interactions.
  • Asynchronous communication does not require that all parties involved in the communication to be present at the same time.
  • Some examples are e-mail messages, discussion boards, blogging, and text messaging over cell phones.




Efficiency of synchronous communication

Both synchronous asynchronous communications are a means of transmitting data. The difference is in the format that the data is transmitted. Asynchronous communications is the method of communications most widely used for PC communication and is commonly used for e-mail applications, Internet access, and asynchronous PC-to-PC communications. Synchronous communications is the more efficient method of communications. Through synchronous communications, data is transmitted as frames of large data blocks rather than bulky individual bytes. One advantage of synchronous is that control information is easily inserted at the beginning and end of each block to ensure constant timing, or synchronization. In the other hand, synchronous communications can avoid from miscommunication. The information that wants to be delivering can be directly received by the other party.
