(1) How Human Beings Communicate and How Computer Information Systems Communicate?
In human society persons are linked to cooperate for deliberate purposes by different means of communications, such as telephone, email, television, which are all composed of human languages. In essence one person utilizes language messages to tell ones who receive these messages how to react accordingly. Commonly in the process of person interaction, the sender of messages can wrap any thought, commands, description, et al, represented in human language without worrying the receiver of messages can not understood the meaning of messages. Sometimes the receiver of messages is not necessary to know where the messages are sourced because the received messages are self-described in languages which are common senses between receivers and senders.
However in the computer information systems，computers can be organized together to commit certain tasks by means of network. Unfortunately different information systems developed by different software incorporations have the same common senses as human beings do. One information system forward a message encoded according to a special format to another information system, which must firstly understood that special format, then decode the received message, and finally to react according to the decoded message meaning. Because of lack of the common sense, the message format meaning and its relevant action must be defined in the message receiving information system.
