2.4 Using Programs with Data

• What is a number data type used for in programming?

  Numeric values
• What are integers used for in programming?

  Counting, indexing, math operations
• What is the purpose of strings in programming?

  Represent and manipulate text
• What is an integer in programming?

  Whole numbers
• What is an example of an integer variable?

  `age = 25`
• What is the purpose of the `print()` method?

  Displays output to the console
• What is the purpose of the `input()` method in programming?

  Accepts user input
• What does Network I/O allow programs to do?

  Communicate over a network
• The number 42 is stored as 00101010
• Understanding data types is crucial for storing and processing information effectively
• An integer variable stores whole numbers
• The `input()` method allows a program to accept user input
• The `=` operator is used to assign data to a variable.


  True
• In programming, data refers to the information that is stored, processed, and manipulated by a computer program
• All information in a computer system is ultimately represented using binary digits
• Booleans in programming can have two values: true or false
• The number 42 is stored as `00101010` in binary
• In programming, variables are used to store and reference data
• The `input()` method is used to accept user input
• Programs use input/output methods to receive data and present results
• File I/O is used to read and write data to files
• In programming, data refers to information that is stored, processed, and manipulated
• All information in a computer system is ultimately represented using binary digits (0s and 1s).


  True
• Match the data type with its example:

  Integer ↔️ `age = 25`

  String ↔️ `name = "John Doe"`

  Boolean ↔️ `isValid = true`
• Values stored in variables can be modified during program execution.


  True
• A boolean variable can only store true or false values.


  True
• Steps for a program to interact with the outside world

  1️⃣ Read user input

  2️⃣ Display output

  3️⃣ Work with files

  4️⃣ Use network connections
• The `print()` method displays the sum and the full name
• What is data in programming?

  True
• File I/O allows programs to read and write data to files.


  True
• The `print()` method is used to display output to the console.


  True
• Key concepts in programming include reading user input, displaying output, and working with files.

  True
• Match the data type with its description:

  Numbers ↔️ Numeric values, such as integers

  Text ↔️ Alphanumeric characters

  Images ↔️ Visual data represented as pixels

  Audio ↔️ Sound data represented as waveforms
• What are the three fundamental data types in programming?

  Integers, strings, booleans
• What is the purpose of variables in programming?

  Store and reference data
