Topic 4: Boolean logic

• What is the primary concern of logic in computer science?

  How we make decisions based on multiple conditions
• Why is understanding the basics of logic crucial for programming?

  It is crucial to writing well-structured code
• What are the two possible values in Boolean Logic?

  True or false
• Who is Boolean Logic named after?

  Mathematician George Boole
• What principle does Boolean logic correspond to in programming?


  The yes/no or on/off principle
• What are Logic Gates used for?

  To implement Boolean logic in hardware
• What are the basic types of Logic Gates?

  • AND
  • OR
  • NOT
• When does an 'AND' gate output true?

  When both inputs are true
• When does an 'OR' gate output true?

  When at least one input is true
• What does a 'NOT' gate output?

  The opposite of the input
• What are the combined Logic Gates mentioned?

  • NOR
  • NAND
  • XOR
  • XNOR
• When does a 'NOR' gate output true?

  Only when both inputs are false
• What does a 'NAND' gate output?

  True unless both inputs are true
• When does an 'XOR' gate output true?

  Only when the inputs are different
• When does an 'XNOR' gate output true?

  Only when the inputs are the same
• What is a Truth Table used for?

  To calculate the results of a logic function for each possible combination of input values
• Why is understanding truth tables vital?

  It is vital for understanding how logic gates work
• What values do variables in Binary Logic take on?

  0 and 1
• What do the values 0 and 1 correspond to in Binary Logic?

  False and true respectively
• What is the significance of Binary Logic in computer science?

  It is the heart of digital electronics and computer science
• What are Logical Operators used for?

  To manipulate true or false values
• What are common Logical Operators?

  • AND
  • OR
  • NOT
  • NAND
  • NOR
  • XOR
  • XNOR
• How are Logical Operators used in programming?

  To specify multiple conditions within a sequence of code
