Explore the com­mu­nic­a­tion definition.

Explore the com­mu­nic­a­tion defin­i­tion based on the Shannon-Weaver Model, out­lining how mes­sages are lin­early encoded, trans­mit­ted, and decoded effectively.

Here we go:

The Communication Definition

Based on the Shannon-Weaver Model of Communication, this is the defin­i­tion of com­mu­nic­a­tion: 1Silfwer, J. (2022, February 18). The Shannon-Weaver Model of Communication. Doctor Spin | The PR Blog. https://​doc​tor​spin​.net/​s​h​a​n​n​o​n​-​w​e​a​v​e​r​-​m​o​d​e​l​-​o​f​-​c​o​m​m​u​n​i​c​a​t​i​on/

Communication = the pro­cess of encod­ing a mes­sage from an inform­a­tion source and trans­mit­ting it through a channel/​medium to be decoded by a receiv­er. 2Silfwer, J. (2020, February 18). The Communication Definition. Doctor Spin | The PR Blog. https://​doc​tor​spin​.net/​c​o​m​m​u​n​i​c​a​t​i​o​n​-​d​e​f​i​n​i​t​i​on/

Strategic Communication Definition

From a pub­lic rela­tions (PR) per­spect­ive, the inten­tion­al dis­sem­in­a­tion of inform­a­tion to influ­ence and per­suade is added to the con­text, provid­ing us with this defin­i­tion of stra­tegic communication:

Strategic com­mu­nic­a­tion = the delib­er­ate pro­cess of encod­ing an optim­ised mes­sage from an inform­a­tion source, trans­mit­ting it through a chosen channel/​medium while min­im­ising noise and ensur­ing that a receiv­er accur­ately decodes it. 3Silfwer, J. (2020, February 18). The Communication Definition. Doctor Spin | The PR Blog. https://​doc​tor​spin​.net/​c​o​m​m​u​n​i​c​a​t​i​o​n​-​d​e​f​i​n​i​t​i​on/

Please note: “Strategic com­mu­nic­a­tions” is syn­onym­ous with “pub­lic rela­tions” (i.e. using com­mu­nic­at­ive means to achieve com­pet­it­ive objectives).

Everything Communicates

As a stark remind­er of the import­ance of con­text, and the fact that “no com­mu­nic­a­tion” also tells us some­thing, PR pro­fes­sion­als often repeat this pop­u­lar mantra:

Everything com­mu­nic­ates.

Communications or Communication?

Have you ever wondered why pub­lic rela­tions pro­fes­sion­als often refer to com­mu­nic­a­tions (with an — s) instead of com­mu­nic­a­tion (without an — s)?

The terms “com­mu­nic­a­tions” and “com­mu­nic­a­tion” are often used inter­change­ably, yet they embody sep­ar­ate con­cepts with­in the con­text of lan­guage, tech­no­logy, and the study of human inter­ac­tion. 4Rivera, K. (2017). Communication vs Communications. Csusm​.edu. https://​www​.csusm​.edu/​c​o​m​m​u​n​i​c​a​t​i​o​n​/​m​a​j​o​r​_​d​i​f​f​e​r​e​n​c​e​s​.​h​tml 5Communication vs. Communications — Differences Between Master’s Programs. (2024, January 2). MastersinCommunications​.com. https://​www​.mas​tersin​com​mu​nic​a​tions​.com/​f​a​q​s​/​c​o​m​m​u​n​i​c​a​t​i​o​n​-​v​s​-​c​o​m​m​u​n​i​c​a​t​i​ons

While com­mu­nic­a­tion cap­tures the human aspect of shar­ing and inter­pret­ing inform­a­tion, com­mu­nic­a­tions delves into the tech­nic­al realm of mes­sage trans­mis­sion sys­tems and technologies.

  • Communication. Refers to trans­mit­ting inform­a­tion and under­stand­ing from one entity to anoth­er. It is a broad term encom­passing all forms of inter­ac­tion that con­vey mean­ing, includ­ing verbal and non­verbal exchanges, writ­ten mes­sages, and visu­al com­mu­nic­a­tions. This concept is found­a­tion­al in the study of com­mu­nic­a­tion the­ory, high­light­ing the mech­an­isms of mes­sage trans­mis­sion, recep­tion, and inter­pret­a­tion between indi­vidu­als or groups. It focuses on the dynam­ics of the exchange, includ­ing the con­text, chan­nels, effect­ive­ness, and bar­ri­ers to understanding.
  • Communications. Refers to the sys­tems, tech­no­lo­gies, and meth­ods for trans­mit­ting mes­sages over dis­tances. It includes the tools and infra­struc­ture that facil­it­ate the exchange of inform­a­tion, such as tele­com­mu­nic­a­tions net­works, the inter­net, and mass media plat­forms. Communications can also per­tain to the fields of study and pro­fes­sion­al prac­tice that deal with these sys­tems, includ­ing engin­eer­ing, tech­no­logy man­age­ment, and inform­a­tion the­ory. While com­mu­nic­a­tion is about the essence of mes­sage exchange and under­stand­ing, com­mu­nic­a­tions focus more on the tech­nic­al and pro­ced­ur­al aspects of how mes­sages are sent and received across dif­fer­ent mediums.

Understanding the nuances between com­mu­nic­a­tions and com­mu­nic­a­tion can provide insights into the nature of trans­mit­ting inform­a­tion and inter­per­son­al and mass com­mu­nic­a­tion dynamics.
