Semiology is distinguished from linguistics because linguistics is a sub-category of semiology that is able to be studied in itself due to the fact that it is not connected to any other sciences. It is only compared to general sciences when related to semiology. Semiology, on the other hand, is a science that studies life of signs within society in conceivable. Semiology is the task of the psychologist to determine its exact place.
Signs are used in everyday life once you leave the house. The control of society like the red hand that appears red but then switches to a walking person to indicate you have the right of way. In mathematics, we have signs that tell us when something must be added, subtracted, divided, multiplied, and so on. We use signs to communicate a meaning that is not the sign itself to people.
Sign designates the whole. The signified would replace the concept within the diagram of communication. Signifier replaces sound-image respectively within the diagram of communication.
Language, as we read in the reading Course in General Linguistics, “It is both a social product of the faculty of speech and a collection of necessary conventions that have been adopted by a social body to permit individuals to exercise that faculty” which means it is a speaking and writing ability inherited to be able to communicate with others. This is related to graphic communication because it communicates ideas to others with hopes that the people will engage and communicate what they learned with others. Graphic communication is composed of synergy, which is the combination of text and image working together to convey an idea. Visual art is a general topic meaning any art work composed of any medium. The visual within graphic communication or the image in your head when you speak could be visual art.
