Which of the following statements are TRUE? Check all that apply
A Boolean value is often stored in the smallest efficiently addressable cell of memory, typically a bit
A type system defines how a type is associated with each expression in the language and includes its rules for
type equivalence and type compatibility
An identifier is just one of the attributes of a variable. In some languages, identifiers do not include the name
of the variable's data type
Descriptors are used for type checking and building the code for the allocation and deallocation operations
Decimal data type, used mostly for business applications, stores a fixed number of decimal digits, with the
implied decimal point at a fixed position in the value
