Symbology explain of barcode.

what is symbology?  another word right!  It is another word for code.   In barcodes, the actual barcode is sustained by a scanner by its authority.  Authority is the fact that the scanner and the barcode are set up to read in the same code in order for them to understand each other.  It is the same as a language.  Such as English, Italian etc.   In this symbology, is the fact that if the one is not in tune with the other, the system does not work.  Now, because of computers, it is possible to always make as much as one wants and how they want to make it.  Thus creating a never ending senario.
