2. What is Communication? Communication is the activity of conveying information  through the exchange of thoughts, messages, or information, as by speech, visuals, signals, writing, or behavior.

3. History of Communication History of communication involves: 1.Speech 2.Symbols 3.Writing

4. Speech Human communication was revolutionized with speech approximately 200,000 years ago. Vocalized form. Based on Syntatic(syntax) combination of lexicals and names.

5. Symbols Symbols introduced 30,000 years ago. A conventional representation of a concept. Imperfection of Speech. Improving both the range at which people could communicate and the longevity of the information.

6. Continued… Symbols involves: 1.Cave paintings 2.Petro glyphs 3.Pictograms 4.Ideograms

7. Cave paintings Cave paintings  are paintings on  cave walls and ceilings, especially those of prehistoric origin. Oldest symbol. Form of rock art. The oldest known cave painting is that of the Chauvet Cave, dating to around 30,000 BC.

8. Petro glyphs Petroglyphs  (also called  rock engravings ) are pictogram and logogram images created by removing part of a rock surface by incising, picking, carving, and abrading. Carvings into a rock surface. It took about 20,000 years for homo sapiens to move from the first cave paintings to the first petroglyphs, which are dated to around 10,000BC.

9. Continued… The most important difference between petroglyphs and pictograms is that petroglyphs are simply showing an event, but pictograms are telling a story about the event The term  petroglyph  should not be confused with pictograph, which is an image drawn or painted on a rock face. 

10. Pictograms A pictogram (pictograph) is a symbol representing a concept, object, activity, place or event by illustration. Pictography is a form of proto-writing whereby ideas are transmitted through drawing. Pictography is a form of writing which uses representational, pictorial drawings.
