A alphabet (of Alpha and Beta , the first two letters of the Greek alphabet) is a whole of Symbole S intended to more or less precisely represent the Phonème S of a Langue.
Each one of these symbols, or Graphème, is also called “letter”; each letter, in theory, should note a phoneme. Certain letters can receive one or more Diacritique S in order to extend the stock of graphèmes if this one is insufficient to note the sounds of the language or to make it possible to avoid ambiguities. Same manner, an alphabet can be wide by the use of Digramme S or of additional letters.
The phonetic evolutions of a language occurring at intervals different from the written evolution, the alphabetical writing does not guarantee in any manner a bijective mapping between the phonemes and the graphèmes, thus in French, /s/ notes as well C , S , S or T . A contrario , S can decide /s/, /z/ or be dumb. Certain languages, like Hungarian, have however a writing quasi-phonetics. In the majority of the cases (except for Hungarian), these are languages written recently whose transcription by means of alphabetical signs was the subject of a planned research.
The first alphabets of the history are the ougaritic Alphabet and the linear Alphabet, two Abjad already classified besides in the alphabetical order Levantine. He is followed by that of the Phéniciens, whose descendants are numerous: as well the Arab writing as the Latin alphabet.
The first two letters of the alphabet Greek, α ( alpha ) and β ( beta ), originate in the first two letters Phénicien born: the Glottal stop and /b/, whose name probably meant “bull” and “house”.
Francoise Briquel-Chatonnet (in charge of research at the laboratory of the old Semitic studies, CNRS - Collège de France) proposed in 2006 a history of the alphabets:

the fundamental alphabet enriched by 15 Vowel S accentuées : * and respectively “E-in-L' has it” and “it E-in-L' O”.
Description of the diacritics :
In French, unlike other languages, the diacritics or the combinations of letters (digraphs and bindings) are not taken into account in the primary alphabetical order, or the sets of letters (crossed words, scrabble, etc) ; these differences of accents or bindings are taken into account only at the ternary level , i.e. after the secondary level (differences in breakage), considered more important, and which follows the principal alphabetical classification of the words according to the 26 classes of letters.
One will refer to the list of the methods of transcription for more details.

Note:
Certain authors of Fantastic literature and Science-fiction developed an imaginary alphabet to give an additional relief to the people and to the cultures which they created:
alphabet of the Codex Seraphinianus
By extension, alphabet becomes a mathematical concept abstracted in mathematical theory from the languages. Mathematically, an alphabet is a unit, whose elements are called letters, from which the words are generated, like continuations of letters. That makes it possible to develop algorithms to with it.
