Information transmission is the process of passing information from the source end to the receiving end. It could be defined as the physical transfer of information from point-to-point or point-to-multipoint in a communication channel.

Electronic means of information transmission include telephone, telegraph, telex, radio, etc. All modern methods of information transmission except prints are electronic means of transmitting information.

Classification of means of information transmission

There are two major means of transmitting information, namely: electronic and non-electronic.

In electronic means, information transmission is from the sender to the receiver via an electronic communication channel. Electronic means of information transmission include telephone, telegraph, telex, radio, etc.

The non-electronic means of transmitting information does not require electronic communication channels. Non-electronic means of transmitting information include prints such as letters, memo, etc.; orals, drum beats, fire lighting, whistling, etc.

All modern methods of information transmission except prints are electronic means of transmitting information. Similarly, all ancient methods of information transmission including prints are non-electronic means of transmitting information.

Modes of receiving information

When information is transmitted from a source to the destination, the receiver of such information could receive it in any of the following modes:

  1. Audio: This is a model that permits the receiver of information to listen to the content of information disseminated at anywhere through a device that produces sound. All methods of transmitting information that enables the receiver to hear sound from the sender utilize audio mode. Examples of audio mode include radio, telephone conversation, oral, beating drums, whistling, and town crying.
  2. Visual: This is a mode of receiving information through a form that can be read or looked at. The receiver does not require an additional device to read such information when they are transmitted. This includes all methods of information transmission that enables the receiver to see and read the transmitted information. Examples are prints, email, telex, fax, internet, gem, fire lighting, and drawing diagrams.
  3. Audio-visual: Audio-visual mode combines the power of audio and visual modes to deliver information that is more understandable to the receiver. These include all methods of disseminating information that enables the receiver to see and hear the transmitted information. Examples of audio-visual modes include television, making representation, satellite communication, internet, and GSM.
