A binary code represents text, computer processor instructions, or other data using any two-symbol system, but often the binary number system's 0 and 1. The binary code assigns a pattern of binary digits (bits) to each character, instruction, etc. For example, a binary string of eight bits can represent any of 256 possible values and can therefore represent a variety of different items.

 In computing and telecommunications, binary codes are used for various methods of encoding data, such as character strings, into bit strings. Those methods may use fixed-width or variable-width strings. In a fixed-width binary code, each letter, digit, or other character is represented by a bit string of the same length; that bit string, interpreted as a binary number, is usually displayed in code tables in octal, decimal, or hexadecimal notation. There are many character sets and many character encodings for them.

One-time pad

Image
A format of one-time pad used by the U.S. National Security Agency , code named DIANA. The table on the right is an aid for converting between plaintext and ciphertext using the characters at l eft as the key. In crytography , the  one-time pad  ( OTP ) is an  encryption  technique that cannot be  cracked , but requires the use of a one-time pre-shared key the same size as, or longer than, the message being sent. In this technique, a  plaintext  is paired with a random secret  key  (also referred to as  a one-time pad ). Then, each bit or character of the plaintext is encrypted by combining it with the corresponding bit or character from the pad using  modular addition . If the key is truly  random , is at least as long as the plaintext, is never reused in whole or in part, and is kept completely  secret , then the resulting  ciphertext  will be impossible to decrypt or break.   It has also been proven that any cipher with the perfect secrecy property must use keys with effectively

International Morse Code

Image
This is the International Morse Code, a famous type of code. Morse code  is a method of transmitting text  information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. It is named for Samuel F. B. Morse , an inventor of the telegraph. The International Morse Code  encodes the ISO basic Latin alphabet , some extra Latin letters, the A rabic numerals  and a small set of punctuation and procedural signals (prosigns ) as standardized sequences of short and long signals called "dots" and "dashes",  or "dits" and "dahs", as in  amateur radio  practice. Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages.
