Arrange the following in the proper sequence of communication :

I. Message
II. Source
III. Decoder
IV. Encoder
V. Destination

  • A.(I), (II), (III), (IV), (V)
  • B.(II), (I), (IV), (III), (V)
  • C.(II), (I), (III), (IV), (V)
  • D.(II), (I), (III), (V), (IV)

Answer: B

The communication process starts with the source, which has the message; the encoder turns the message into a code, the decoder reads the code and the destination receives it. The sequence is therefore source, message, encoder, decoder, destination, which is II, I, IV, III, V, option (B). Option (A) puts the message before the source, option (C) puts the decoder before the encoder, and option (D) puts the decoder and the destination before the encoder, so none of them can occur, since a message cannot be decoded before it is encoded.
