Principles of Programming*

• Why are standards needed?

  Ensures devices integrate with one another. A consortium will come together and discuss what is needed to ensure interoperability.
• What is software standardisation?

  Ensures the software's interoperability is consistent throughout all platforms.
• Why is there ambiguity in natural language?

  Multiple meanings of words, sentence structure, and context can lead to ambiguity in natural language.
• What is Natural Language Processing?

  Machine learning technology that gives computers the ability to interpret, manipulate and comprehend human language.
• What is Backus-Naus Form?

  Way of writing down the grammar of a language. It defines rules that must be followed for the code to be syntactically correct.
• Format of Backus-Naus Form?

  First- <RuleName> - RuleName

  Second- ::=

  Third- 0|1|2 - Terminals, 1 or 2 or 3

  Third- <Recursion> ::= <RuleName>|<RuleName> <Recursion> - Recursion rule repeating RuleName
• What is a syntax diagram?

  A diagrammatic method for humans to understand the rules of the syntax of a programming language.
• This symbol represents a Non-Terminal symbol.

  
• This symbol represents a terminal symbol.

  
• This symbol represents a flow of information symbol.

  
• This is disjunction (or gate).

  
• This is conjunction (and gate).

  
• This is a recursion.

  
• Functionality requirements for a computer based solution is that correct results must be produced from given inputs.
• Performance requirements for a computer based solution is that results must be produced within a suitable timeframe.
• Natural user interface relies on intuitive actions related to everyday human behaviour, such as touch screen.
• An immersive interface places one or more of the user sense into a computer generated virtual environment, such as VR.
