Huffman coding. Huffman tree generated from the exact frequencies of the text "this is an example of a huffman tree". Encoding the sentence with this code requires 135 (or 147) bits, as opposed to 288 (or 180) bits if 36 characters of 8 (or 5) bits were used (This assumes that the code tree structure is known to the decoder and thus does not ...
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
Dictionary.com meanwhile says it is "used as a nonsense word by children to express approval or to represent the longest word in English." [ 10 ] The word contains 34 letters and 14 syllables. Legal action
Phonics is a method for teaching reading and writing to beginners. To use phonics is to teach the relationship between the sounds of the spoken language ( phonemes ), and the letters ( graphemes) or groups of letters or syllables of the written language. Phonics is also known as the alphabetic principle or the alphabetic code. [1]
A codec is a device or computer program that encodes or decodes a data stream or signal. [1] [2] [3] Codec is a portmanteau of coder/decoder. [4] In electronic communications, an endec is a device that acts as both an encoder and a decoder on a signal or data stream, [5] and hence is a type of codec. Endec is a portmanteau of encoder/decoder.
Decoding or decode may refer to: is the process of converting code into plain text or any format that is useful for subsequent processes. Science and technology [ edit ]
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as ...
The proof for list-decoding capacity is a significant one in that it exactly matches the capacity of a -ary symmetric channel . In fact, the term "list-decoding capacity" should actually be read as the capacity of an adversarial channel under list decoding.
