EVALUATION

1. What is information transmission?
2. Explain the two methods of transmitting information.

• Modern methods:

1. Prints: This is the process of producing texts and images on paper to send information from one place to another.

2. Telephone: This is the process of transmitting sound or speech to a distant point by an electric device.

3. Telex: It is used to transmit written messages or information via cable from one place to another through a teleprompter.

4. Radio: This is an electronic device that detects and demodulate and amplifies transmitted signals.

5. Television: This is a means of transmitting dynamic or sometimes static images, with accompany sound, via electric or electromagnetic signals.

6. Fax: This is a method or device for transmitting documents, drawings, photographs etc. by means of radio or telephone for exact production elsewhere.   

7. Satellite: This is an object that orbits around another object. The artificial satellites have dish, which transmit information into space and therefore makes such available for other satellites.  

8. Internet: This is the global communication network that allows almost all computers worldwide to connect and exchange information.

9. GSM: Global System of Mobile Communication (GSM) is an improved way of telephoning without the use of telephone cables.
