  Code \Code\ (k[=o]d), n. [F., fr. L. codex, caudex, the stock or
     stem of a tree, a board or tablet of wood smeared over with
     wax, on which the ancients originally wrote; hence, a book, a
     writing.]
     1. A body of law, sanctioned by legislation, in which the
        rules of law to be specifically applied by the courts are
        set forth in systematic form; a compilation of laws by
        public authority; a digest.
        [1913 Webster]
  
     Note: The collection of laws made by the order of Justinian
           is sometimes called, by way of eminence, "The Code" .
           --Wharton.
           [1913 Webster]
  
     2. Any system of rules or regulations relating to one
        subject; as, the medical code, a system of rules for the
        regulation of the professional conduct of physicians.
        [1913 Webster]
  
     3. Any set of symbols or combinations of symbols used for
        communication in any medium, such as by telegraph or
        semaphore. See Morse code, and error-correcting code.
        [PJC]
  
     Note: A system of rules for making communications at sea by
           means of signals has been referred to as the
  
     naval code.
        [1913 Webster]
  
     4. Any set of standards established by the governing
        authority of a geopolitical entity restricting the ways
        that certain activities may be performed, especially the
        manner in which buildings or specific systems within
        buildings may be constructed; as, a building code; a
        plumbing code; a health code.
        [PJC]
  
     5. Any system used for secrecy in communication, in which the
        content of a communication is converted, prior to
        transmission, into symbols whose meaning is known only to
        authorized recipients of the message; such codes are used
        to prevent unauthorized persons from learning the content
        of the communication. The process of converting a
        communication into secret symbols by means of a code is
        called encoding or encryption. However, unauthorized
        persons may learn the code by various means, as in
        code-breaking.
        [PJC]
  
     6. An error-correcting code. See below.
        [PJC]
  
     7. (Computers) The set of instructions for a computer program
        written by a programmer, usually in a programming language
        such as Fortran, C, Cobol, Java, C++, etc.; also, the
        executable binary object code. All such programs except
        for the binary object code must be converted by a
        compiler program into object code, which is the
        arrangement of data bits which can be directly interpreted
        by a computer.
        [PJC]
  
     Code civil or Code Napoleon, a code enacted in France in
        1803 and 1804, embodying the law of rights of persons and
        of property generally. --Abbot.
  
     error-correcting code (Computers) A set of symbols used to
        represent blocks of binary data, in which the original
        block of data is represented by a larger block of data
        which includes additional bits arranged in such a way that
        the original data may be read even if one or more of the
        bits of the encoded data is changed, as in a noisy
        communicaiton channel. Various codes are available which
        can correct different numbers or patterns of errors in the
        transmitted data. Such codes are used to achieve higher
        accuracy in data transmission, and in data storage devices
        such as disk drives and tape drives.
  
     object code (Computers) the arrangement of bits stored in
        computer memory or a data storage device which, when fed
        to the instruction processor of a computer's central
        processing unit, can be interpreted directly as
        instructions for execution.
  
     genetic code (Biochemistry, genetics) The set of
        correspondences between sequences of three bases (codons)
        in a RNA chain to the amino acid which those three bases
        represent in the process of protein synthesis. Thus, the
        sequence UUU codes for phenylalanine, and AUG codes for
        methionine. There are twenty-one naturally-occurring amino
        acids, and sixty-four possible arrangements of three bases
        in RNA; thus some of the amino acids are represented by
        more than one codon. Several codons do not represent amino
        acids, but cause termination of the synthesis of a growing
        amnio acid chain.
        [1913 Webster +PJC]
  
     Note: The genetic code is represented by the following table:
