For example: the word "been" might be depicted by a rebus showing an illustrated bumblebee next to a plus sign (+) and the letter "n". It was a favourite form of ...
Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
Bencode. Bencode (pronounced like Bee-encode) is the encoding used by the peer-to-peer file sharing system BitTorrent for storing and transmitting loosely structured data. [1] It supports four different types of values: byte strings, integers, lists, and. dictionaries (associative arrays). Bencoding is most commonly used in torrent files, and ...
One-time pad. 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 left as the key. In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single ...
Decodable text is a type of text often used in beginning reading instruction. Decodable texts are carefully sequenced to progressively incorporate words that are consistent with the letters and corresponding phonemes that have been taught to the new reader. Therefore, with this type of text new readers can decipher words using the phonics ...
Parsing. Parsing, syntax analysis, or syntactic analysis is the process of analyzing a string of symbols, either in natural language, computer languages or data structures, conforming to the rules of a formal grammar. The term parsing comes from Latin pars (orationis), meaning part (of speech). [1]
This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa. It is the basis for some popular 8-bit character sets and the first two blocks of characters in Unicode. As of July 2024, 1.2% of all web sites use ISO/IEC 8859-1. [1][2] It is the most declared single-byte character encoding, but as Web ...
