The Advanced Encryption Standard ( AES ) is a specification for the encryption of electronic data established by the U. S. National Institute of Standards and Technology ( NIST ) in 2002.

* awb-AMR-WB audio, used primarily for speech, same as the ITU-T's G. 722. 2 specification.

Some architectures use a particular register as an accumulator in some instructions, but other instructions use register numbers for explicit operand specification.

In electronic filter design, a filter specification may require that within the filter passband, the gain is nominally 0 dB +/- a small number of dB, for example within the +/- 1 dB interval.

High specification luxury coaches are often chartered by companies for executive or VIP transport.

Due to limitations inherent in the Peripheral Component Interconnect ( PCI ) specification for driving slots, backplanes are now offered as passive and active.

The standard simply provides a shorthand way of claiming that certain specifications are met, while encouraging manufacturers to adhere to a common method for such a specification.

* BS 88 a specification for cartridge fuses for voltages up to and including 1000 V a. c. and 1500 V d. c.

* BS 4573 a specification for 2-pin reversible plugs and shaver socket-outlets

* BS 8888 for engineering drawing and technical product specification

A bibliographic classification, extended by systematic auxiliary schedules for composite specification ( 4 volumes ).

The HTTP / 1. 1 header specification for a HTML document must label an appropriate encoding in the Content-Type header, missing < tt > charset =</ tt > parameter results in acceptance of ISO-8859-1 ( so HTTP / 1. 1 formally does not offer such option as an unspecified character encoding ), and this specification supersedes all HTML ( or XHTML ) meta element ones.

It also can use keys up to 256 bits ( a specification requirement for submissions to the AES contest ).

Before there was an official standard for C, many users and implementors relied on an informal specification contained in a book by Ritchie and Brian Kernighan ; that version is generally referred to as " K & R " C. In 1989 the American National Standards Institute published a standard for C ( generally called " ANSI C " or " C89 ").

The next year, the same specification was approved by the International Organization for Standardization as an international standard ( generally called " C90 ").

* Prototype Verification System ( PVS ), a mechanized environment for formal specification and verification.

Many computer languages require garbage collection, either as part of the language specification ( e. g., Java, C #, and most scripting languages ) or effectively for practical implementation ( e. g., formal languages like lambda calculus ); these are said to be garbage collected languages.

It is a fundamental specification for many common combustion engines.

However, in some operating systems, a name may include a specification of type that means a directory can contain an identical name for more than one type of object such as a directory and a file.

The specification defines an environment that allows multiple high-level languages to be used on different computer platforms without being rewritten for specific architectures.

** Specification – specifying requirements of a design solution for a product ( product design specification ) or service.

" No independent standard was developed for DOM Level 0, but it was partly described in the specification of HTML4.

The specification of the objective function of which the optimization is desired.

Users of the system perform these tests, which developers derive from the client's contract or the user requirements specification.

Common Lisp was developed to standardize the divergent variants of Lisp ( though mainly the MacLisp variants ) which predated it, thus it is not an implementation but rather a language specification.

Here, a " specification " can be manifested as either a plan or a finished product, and " primitives " are the elements from which the design object is composed.

IEEE 1101. 10 covers the additional mechanical and EMI features required for VITA 1. 1-1997 ( R2002 ) which is the VME64 Extensions standard as well as PICMG 2. 0 ( R3. 0 ) which is the CompactPCI specification.

LTI filters can be completely described by their frequency response and phase response, the specification of which uniquely defines their impulse response, and vice versa.

Some 4GLs have integrated tools which allow for the easy specification of all the required information:

It was formally defined as such by the Internet Engineering Task Force ( IETF ) with the mid-1993 publication of the first proposal for an HTML specification: " Hypertext Markup Language ( HTML )" Internet-Draft by Berners-Lee and Dan Connolly, which included an SGML Document Type Definition to define the grammar.

After the HTML and HTML + drafts expired in early 1994, the IETF created an HTML Working Group, which in 1995 completed " HTML 2. 0 ", the first HTML specification intended to be treated as a standard against which future implementations should be based.

The W3C is developing a comprehensive test suite to achieve broad interoperability for the full specification by 2014, which is now the target date for Recommendation.

* the national standard IT specification for smart ticketing in the UK of which ITSO is the guardian

The Atari standard joystick, developed for the Atari 2600, released in 1977, was a digital joystick, with a single fire button, and connected via a DE-9 connector, the electrical specifications of which were for many years the de-facto standard digital joystick specification.

In 1934 the Japanese government issued a military specification for the shin guntō ( new army sword ), the first version of which was the Type 94 Katana, and many machine-and hand-crafted swords used in World War II conformed to this and later shin guntō specifications.

No known extensions attacks have been found against the current HMAC specification which is defined as H ( key1 ∥ H ( key2 ∥ message )) because the outer application of the hash function masks the intermediate result of the internal hash.

Since there are many different reference ellipsoids the latitude of a feature on the surface is not unique: this is stressed in the ISO standard which states that " without the full specification of the coordinate reference system, coordinates ( that is latitude and longitude ) are ambiguous at best and meaningless at worst ".

New versions of the OpenGL specification are regularly released by the Khronos Group, each of which extends the API to support various new features.

The OpenGL ARB released a series of manuals along with the specification which have been updated to track changes in the API.

A language is typed if the specification of every operation defines types of data to which the operation is applicable, with the implication that it is not applicable to other types.

Forged 16 " flat wheels of the style used on the 928 were optional, but fitment specification was that of the 911 which the 924 shared wheel offsets with.

The 968 Turbo RS was available in two variations ; a 337 bhp version using the K27 turbocharger from the Turbo S, which was built to the German ADAC GT specification ( ballast added to bring the car up to the 1350 kg minimum weight limit ), and an international spec version which used a KKK L41 turbocharger producing 350 bhp and was reduced to 1212 kg in weight.

A regular expression is written in a formal language that can be interpreted by a regular expression processor, which is a program that either serves as a parser generator or examines text and identifies parts that match the provided specification.
