Go back to Question 6

Answer 5

False. According to the online document titled Java API for JSON Processing: An Introduction to JSON , "JSON can represent two structured types: objects and arrays. An object is an unordered collection ofzero or more name/value pairs. An array is an ordered sequence of zero or more values. The values can be strings, numbers, booleans, null, and these twostructured types."

Go back to Question 5

Answer 4

False. It is important to note that even though JSON is based on JavaScript syntax, JASON is not JavaScript nor is it any other programming language. Infact, it is not a programming language at all. JSON is simply "a lightweight, text-based, language-independent data exchange format" -- nothing more and nothing less.

Go back to Question 4

Answer 3

False. Visual Basic is not based on the C-family of languages. Visual Basic is based on the BASIC programming language that came into existence in 1964. The C programming language came into existence independently in 1972.
