Understanding the use of data types

• What is the purpose of data types in programming?

  Classify and define data
• What type of data does the Float data type store?

  Numbers with decimals
• The Boolean data type represents true or false values.


  True
• Match the data type with its description:

  Integer ↔️ Whole numbers without decimals

  Float ↔️ Numbers with decimals

  String ↔️ Textual data enclosed in quotes

  Boolean ↔️ Represents true or false values
• What are integers commonly used for in programming?

  Counting and indexing
• Floats are used for scientific and engineering calculations.
• Floating-point data types allow for precise storage of real numbers.


  True
• Floating-point precision is limited by the storage bits.
• Match the character encoding standard with its characteristic:

  ASCII ↔️ Uses 7 bits

  Unicode ↔️ Uses 16-32 bits
• What is the value range of integer data types?

  Whole numbers, no decimals
• Integers require less memory than floating-point numbers.
• Match the operation with its purpose in integer arithmetic:

  Addition ↔️ Summing two integers

  Multiplication ↔️ Product of two integers

  Division ↔️ Quotient of two integers

  Subtraction ↔️ Difference of two integers
• Floating-point numbers use more memory than integers.
• What arithmetic operations can be performed with floating-point numbers?

  Addition, subtraction, multiplication, division
• Floating-point numbers require less memory than integers.

  False
• The ASCII encoding standard uses 7 bits.
• What data type is used to store text in programming?

  String
• Strings store single characters like character data types.

  False
• Boolean data types typically use 1 byte of memory.
• What are the two categories of data types?

  Numerical and non-numerical
• Match the numerical data type with its description:

  Integer ↔️ Whole numbers without decimals

  Float ↔️ Numbers with decimal points
• How are data types broadly categorized?

  Numerical and non-numerical
• Numerical data types are used for mathematical operations and calculations


  True
• Match the data type with its description:

  Integer ↔️ Whole numbers without decimals

  Float ↔️ Numbers with decimal points

  String ↔️ Textual data enclosed in quotes

  Boolean ↔️ Represents true or false values
• Numerical data types have a defined range of values
• What kind of numbers do integer data types represent?

  Whole numbers
• What do floating-point data types represent?

  Numbers with decimal points
• What is one advantage of floating-point data types?

  Accurate representation of real numbers
• How are strings enclosed in programming languages like Python?

  Single or double quotes
• What are the two possible values of a boolean data type?

  True or false
• What are the two possible values of a boolean data type?

  True or False
• Match the logical operations with their descriptions:

  and ↔️ Returns True if both operands are true

  or ↔️ Returns True if either operand is true

  not ↔️ Inverts the value of the operand
• How much memory does a boolean data type typically use?

  1 byte
• The `not` boolean operation inverts the value of the operand.

  True
• An empty string is evaluated as False in boolean logic.
• What is an example of a string data type?

  "Hello"
• Order the following characteristics to differentiate numerical and non-numerical data types:

  1️⃣ Value Range

  2️⃣ Operations

  3️⃣ Memory Usage
• A float is a data type used for numbers with decimal points.
• What is the primary purpose of a string data type?

  Storing text
• The Integer data type is used to store whole numbers without decimals.
