12Area code 404 — covers Atlanta and its immediate neighbors, roughly within Interstate 285.Originally, it covered all of Georgia when the area code system was first created in the 1940s and implemented in 1951. On July 1, 1954, area code 912 was assigned to… …
13Chaitin's constant — In the computer science subfield of algorithmic information theory, a Chaitin constant or halting probability is a real number that informally represents the probability that a randomly constructed program will halt. These numbers are formed from …
14Entropy encoding — In information theory an entropy encoding is a lossless data compression scheme that is independent of the specific characteristics of the medium. One of the main types of entropy coding creates and assigns a unique prefix free code to each… …
15Shannon's source coding theorem — In information theory, Shannon s source coding theorem (or noiseless coding theorem) establishes the limits to possible data compression, and the operational meaning of the Shannon entropy.The source coding theorem shows that (in the limit, as… …
161-1-2 — 112 (one one two) is the emergency telephone number in the European Union member states, the Republic of Colombia (South America) and worldwide (on GSM mobile networks).In 1991, the European Union established 112 as the universal emergency number …
17Huffman coding — Huffman tree generated from the exact frequencies of the text this is an example of a huffman tree . The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 bits, as opposed of 288 bits if 36… …
18Kraft's inequality — In coding theory, Kraft s inequality, named after Leon Kraft, gives a necessary and sufficient condition for the existence of a uniquely decodable code for a given set of codeword lengths. Its applications to prefix codes and trees often find use …
19Unary coding — is an entropy encoding that represents a natural number, n , with n − 1 ones followed by a zero. For example 5 is represented as 11110. Some representations use n − 1 zeros followed by a one. The ones and zeros are interchangeable without loss of …
