INFORMATION TRANSMISSION (JS1 1ST TERM)

INFORMATION TRANSMISSION

Definition of Information Transmission

Information Transmission is the process of sending out processed data from one person or place to another in a meaningful form through a communication medium.

Human beings have been transmitting information since ancient times through different method and means.

Methods of Transmitting Information

1.       Ancient; and

2.       Modern means of transmitting information.

Ancient Methods of Transmitting Information

These are the methods used by our forefathers. They include the following:

a.  Oral (Face to Face) Information/Communication

b.  Town Crier

c.  Smoky fire/Smoke

d.  Whistling

e.  Drawing diagrams

f.  Beating Drums

g. Making representation

Note: All of the above have been discussed earlier in the technology of different information age, except whistling.

Whistling:  Blowing of the whistle could be used as a means of drawing peoples’ attention or passing information across in some places.

Modern Methods of Transmitting Information

With the development in technology, it is now possible to pass information straight to the audience. Ancient means of communication have been replaced by more efficient modern ones. Modern means of transmitting information include:

a. Printing Machine

Printed materials are just like typewritten ones. Printing allows mass production of informative materials that could be spread far and wide e.g. production of invitation cards, handbills newspapers etc.

b. Radio

      Voice information is broadcast to group of people in geographical location at the same time within few minutes.

c.  Television

   This is used to broadcast information in form of both voice and pictures to people in different location.

d.  Internet (INTERnationalNETwork)

     This is a global system of interconnected computer networks of private, public, academic, business, and government networks. Anyone at any location with the right devices can have access to the information shared on the internet.

e. Fax

    This transmit text and graphic messages from one location to the other, it might be within the country or outside the country with the use of series of numbers called fax number.

f.  Telephone

Telephone allows people’s voices to be transmitted over long or short distances.

g. Telex

A telex machine is used to transmit textual information from one person to another usually over a long distance.

h. Satellite

A satellite is an object which has been placed into the orbit by human endeavor in other to improve sending radio, telephone and internet signals to any part of the world. Such objects are sometimes called artificial satellite to distinguish from natural satellite such as moon.

i.  GSM

GSM means Global System for Mobile Communication. We use this to send and receive phone calls. One benefit of GSM phone is the addition of SIM card or Subscriber Identification Module.

 

Task one: Identify the ancient methods of communication still in practice in your area.

Classification of means of transmitting information

Both ancient and the modern means of transmitting information can be classified under the following:

i.   Electronic means; and

ii. Non-Electronic means.

Electronic means: Those that involves or require an electronic communication channels. Electronics means include prints, telephone, Radio, Television and Satellite broadcasts, Fax, Internet and GSM.

Non-Electronic means: Those that do not involves or require electronic communication channels. Non-electronic means include Oral (word of mouth), Beating of drums, Fire lighting, handwritten messages, traditional/local post office, whistling, drawing diagrams and making representations, Drama, newspapers, magazines, etc.

 

All modern methods of information transmission except prints are electronic means of transmitting the information.

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

Examples of these include:

i.         Newspaper

ii.       Dailies

iii.      Magazines

Modes of Receiving Information

Human beings receive information through the sense organs and could be interpreted by the brain. Therefore, messages can be received by three major ways. They include:

i.        Audio

ii.      Visual

iii.     Audio-visual

Audio: This is a mode of communication permits the receiver of information to listen to the content of information disseminated anywhere through a device that produces sound. Examples are through Radio, Telephone, Beating of drums, Town crying, etc.

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. Examples are prints, Drawings, Computer printouts, Telex, fax machines etc.

Audio-visual: Audiovisual mode combines the power of audio and visual modes to deliver information that is more understandable to the receiver. Examples of audio-visual modes include television, making representation, satellite communication, the internet, and GSM.
