It is always necessary to tell useful and true information from the waste with which libraries and Mass Media are filled not to mention internet.
Information supposes the existence of three components that are the source, the consumer and the transmitting environment. Information can't be got, transmitted and kept without any changes. And the carrier of information is usually the message. Message is the coded equivalent to the events that are fixed by the source of information and expressed with the help of sequence of physical symbols such as alphabet that make the perfect structure.
The communication channel is the way of the messages transmission. And the messages may be transmitted only in the certain form proper only for this communication channel. The signal is the sign and the physical process, indication, etc. that spreads in the communication channel and has the message about the certain event, the state of objects, watching and control results, etc. For example, the electric signals spread in the electric circuits. Acoustic signals spread in the gas and liquid areas.
The signal that carries information transmitted by the environment and got by the consumer has the certain meaning and importance for him/her. This is the result of the special agreements that are made between the source and the consumer of information according to which the signal is understood in the certain meaning.
When information is needed to be transmitted it is usually coded into the message that is formed with the number of certain signal that may be both individual and known to certain group of people or one person and common that means known to all people. The vivid example of common signals is alphabet.
