A program specification is the definition of what a computer program is expected to do. It can be informal, in which case it can be considered as a user manual from a developer point of view, or formal, in which case it has a definite meaning defined in mathematical or programmatic terms.
A programming language specification can take several forms, including the following: An explicit definition of the syntax and semantics of the language. While syntax is commonly specified using a formal grammar, semantic definitions may be written in natural language (e.g., the approach taken for the C language), or a formal semantics (e.g., the Standard ML [3] and Scheme [4] specifications).
Computer hardware and software standards are technical standards instituted for compatibility and interoperability between software, systems, platforms and devices. Hardware [ edit ]
The activities related to working with software requirements can broadly be broken down into elicitation, analysis, specification, and management. [3] Note that the wording Software requirements is additionally used in software release notes to explain, which depending on software packages are required for a certain software to be built ...
A software requirements specification (SRS) is a description of a software system to be developed.It is modeled after the business requirements specification.The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
A specification language is a formal language in computer science used during systems analysis, requirements analysis, and systems design to describe a system at a much higher level than a programming language, which is used to produce the executable code for a system.
A functional specification (also, functional spec, specs, functional specifications document (FSD), functional requirements specification) in systems engineering and software development is a document that specifies the functions that a system or component must perform (often part of a requirements specification) (ISO/IEC/IEEE 24765-2010).
In computer science, formal specifications are mathematically based techniques whose purpose is to help with the implementation of systems and software. They are used to describe a system, to analyze its behavior, and to aid in its design by verifying key properties of interest through rigorous and effective reasoning tools.
