Data Representation and Types Quiz

Computer Function and Data Structure

• A computer's main function is to process, store, and communicate information.

Type System in Programming Languages

• A type system is a set of rules that govern how a programming language defines and uses data types.
• The primary role of a type system is to ensure the correctness of data operations by preventing type errors at compile or runtime.

Data Types and Type System

• Data types define what kind of data can be stored in a variable, how it is stored, and what operations can be performed on it within a type system.
• The benefit of using a type system in programming languages is to prevent type errors, improve code readability, and enhance code maintainability.

Primitive Data Types

• There are two types of primitive data types: numeric and non-numeric.
• Boolean values are typically implemented in programming languages as a single bit (0 or 1) or an enumeration of true or false.

Numeric Data Types

• There are three types of numeric data types: integer, floating-point, and complex.

Basic and Built-in Types

• The difference between a basic type and a built-in type is that a basic type is a fundamental data type, while a built-in type is a pre-defined data type provided by the programming language.

Composite Data Types

• Examples of composite data types include arrays, lists, and structures.
• Composite types are derived data types that are composed of multiple values of other data types.

Abstract Data Types

• An abstract data type (ADT) is a high-level data type that provides a way to define and manipulate data without exposing the underlying implementation details.
• An example of an abstract data type is a stack, which can be implemented using an array or a linked list.

Compound and Primitive Types

• The difference between a compound type and a primitive type is that a compound type is composed of multiple values of other data types, while a primitive type is a single, self-contained data type.
