Code /(kōd)/

Code

n.
  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.
  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.
  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.
  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.
  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.
  6. An error-correcting code. See below.
  7. 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. (Computers)
  8. To convert (a text or other information) into a encoded form by means of a code{5}.
  9. To write a computer program in a programming language; as, to code a sorting routine.

Phrases & Compounds

Code civil
a code enacted in France in 1803 and 1804, embodying the law of rights of persons and of property generally.
error-correcting code
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.
genetic code
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.

Code

v. i.
  1. To serve as the nucleotide sequence directing the synthesis of a particular amino acid or sequence of amino acids in protein biosynthesis; as, this sequence of nucleotides encodes the hemoglobin alpha chain.. (Biochemistry, genetics)
