>> In computer science, an alphabet is a finite non-empty set. The elements of an alphabet are called the letters or symbols of the alphabet. >> An example of an alphabet is {\displaystyle \{-,\cdot \}} {\displaystyle \{-,\cdot \}} which may be used for Morse code or {begin, if, else, for, while} which may be the keywords of a Programming language. >> The set of natural numbers is not an alphabet because as it is not finite. >> The alphabet which is used the most in computer science is {0,1}. It is called the **binary alphabet** because it contains two symbols. An alphabet can be used to make a string (or word). This is a finite Sequence of letters from the alphabet. For example, a string of length 5 over {0,1} is 01101. >>> binary alphabet Таки можно шестнадцатеричное число называть символом шестнадцатеричного алфавита. Т.е. ше/тнадцатеричное число - буква шестнадцатеричного алфавита, она же буква.
