05 Non Computer Tools for Transmitting and Receiving


Tools, or more accurately systems, used to transmit and receive that do not directly use computers include:
  • mail
  • phone
  • fax
  • radio
  • television

Each of the above systems includes various non-computer and computer based tools.

Furthermore, each can be described using the communication concepts introduced at the start of this chapter. For example, radio could be described as a synchronous simplex transmission method. 

Synchronous because the signal is received in time with its transmission rate, and simplex because the signal travels in one direction only, namely from the radio transmitter to each radio receiver.
