Definition 3: Syntax is meant to include all structural propertiesof <strong>the</strong> process of setting up information. At this second level weare only concerned with <strong>the</strong> actual sets of symbols (codes) and<strong>the</strong> rules governing <strong>the</strong> way <strong>the</strong>y are assembled into sequences(grammar and vocabulary) independent of any meaning <strong>the</strong>ymay or may not have.Note: It has become clear that this level consists of two parts,namely:A) Code: Selection of <strong>the</strong> set of symbols usedB) The syntax proper: inter-relationships among <strong>the</strong> symbols.A) The Code: The System of Symbols Used for Setting up<strong>In</strong>formationA set of symbols is required for <strong>the</strong> representation of informationat <strong>the</strong> syntax level. Most written languages use letters, but a verywide range of conventions exists: Morse code, hieroglyphics, internationalflag codes, musical notes, various data processing codes,genetic codes, figures made by gyrating bees, pheromones (scents)released by insects, and hand signs used by deaf-mute persons.Several questions are relevant: What code should be used? Howmany symbols are available? What criteria are used for constructing<strong>the</strong> code? What mode of transmission is suitable? How couldwe determine whe<strong>the</strong>r an unknown system is a code or not?The number of symbols: The number of different symbols q,employed by a coding system, can vary greatly, and dependsstrongly on <strong>the</strong> purpose and <strong>the</strong> application. <strong>In</strong> computer technologyonly two switch positions are recognised, so that binary codeswere created which comprise only two different symbols. Quaternarycodes comprising four different symbols, are involved in allliving organisms. The reason why four symbols represent an optimumin this case, is discussed in Chapter 6. The various alphabetsystems used by different languages consist of from 20 to 35 letters,and this number of letters is sufficient for representing all <strong>the</strong>sounds of <strong>the</strong> language concerned.
