（2）Berlo’sModel

InTheProcessofCommunication,DavidBerloprovidedoneofthesimplestandmostusefulcontemporarymodelsofcommunication.Berlo’ssource-message-channel-receivermodel,commonlyreferredtoastheSMCRmodel,hassixbasicconstituents:

1.Thesource

2.Theencoder

3.Themessage

4.Thechannel

5.Thedecoder

6.Thereceiver

Inorderforustocommunicatewitheachother,wehavetotranslateourthoughtsintosymbols（encodethem）inordertotransmitmessages.Inourcontemporaryworld,wehavetorelyontechnologytoencodeanddecodeourmessages.

Berlo’smodelislinear,andthereforelimited.

（3）ShannonandWeaver’sModel

ShannonandWeaver’scommunicationmodel（fig.1.2）introducestheconceptsofnoise,entropy,redundancy,bit,feedback,andchannelcapacity.Noiseisanythinginthechannel（ormedium）thatinterfereswiththemessage.

AseriouslimitationoftheShannonandWeavermodelisthatitdoesnottakemeaningintoaccount.
