Flow diagram. In computing, serialization (or serialisation) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer environment).

Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [ 1]
Comparison of data-serialization formats. This is a comparison of data serialization formats, various ways to convert complex objects to sequences of bits. It does not include markup languages used exclusively as document file formats .
Equality is used in many programming language constructs and data types. It is used to test if an element already exists in a set, or to access to a value through a key.. It is used in switch statements to dispatch the control flow to the correct branch, and during the unification process in logic programmi
Delimiter-separated values. Formats that use delimiter-separated values (also DSV) [ 2]: 113 store two-dimensional arrays of data by separating the values in each row with specific delimiter characters. Most database and spreadsheet programs are able to read or save data in a delimited format. Due to their wide support, DSV files can be used in ...
Order is preserved in lists of values and in hashes with both keys and values, and the two can be intermingled. [221] PHP also supports strings, which can be used with single quotes, double quotes, nowdoc or heredoc syntax. [222] The Standard PHP Library (SPL) attempts to solve standard problems and implements efficient data access interfaces ...
ISO 639 is a standardized nomenclature used to classify languages. [ 1] Each language is assigned a two-letter (set 1) and three-letter lowercase abbreviation (sets 2–5). [ 2] Part 1 of the standard, ISO 639-1 defines the two-letter codes, and Part 3 (2007), ISO 639-3, defines the three-letter codes, aiming to cover all known natural ...
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.
