• AND OPERATION: In order to understand the logic AND operation in which a lamp is connected to a battery using two switches S and S connected in series considered as two inputs. There are four possible states of these two switches which are given below:
• (i) When S and S are both open, the lamp is OFF. (ii) When S is open but S closed, the lamp is OFF. (iii) When S is closed but S open, the lamp is OFF. (iv) When both S AND S are closed, the lamp is ON.
• Symbol for AND operation is dot (.). Its Boolean expression is: X = A . B and is read as “ X equals A AND B”. 
• Important 10th class physics chapter 7 important questions for all students of Punjab  Textbook Board.
• OR OPERATION: In order to understand the logic OR operation see the circuit. A lamp is connected to a battery using two switches S and S connected in parallel considered as two inputs. There are four possible states of these two switches which are given below:
• Important 10th class physics chapter 7 exercise for all students of Punjab  Textbook Board.
• (i) When S and S are open, the lamp is OFF. (ii) When S is open and S closed, the lamp is ON. (iii) When S is closed and S open, the lamp is ON (iv) When both S and S are closed, the lamp is ON.
• OR operation is represented by the symbol of plus (+). Boolean expression for OR operation is : X = A + B and is read as “ X equals A OR B”. 
• Important physics class 10 chapter 7 full explanation for all students of Punjab  Textbook Board.
• NOT OPERATION: In order to understand NOT operation, see the circuit. A lamp is connected to a battery with a switch S, in parallel When the switch is open, current will pass through the lamp and it will glow. When switch is closed, no current will pass through the lamp due to large resistance of its filament and it will not glow. 
• Important class 10 physics chapter 7 exercise solutions for all students of Punjab  Textbook Board.
• NOT operation is represented by a line or bar over the symbol i.e., X = A\ and is read as “X equals A NOT ”. It means NOT operation changes the state of a Boolean variable.
• Important important question of physics class 10 chapter 7 for all students of Punjab  Textbook Board.
• NAND GATE: NAND operation is simply an AND operation followed by a NOT operation. For example, NAND gate is obtained by coupling a NOT gate with the output terminal of the AND gate. 
• The NOT gate inverts the output of the AND gate. The output of the NAND equals A.B\ and is written as X = A.B\. It is read as X equals A AND B NOT. 
• NOR GATE: The NOR operation is simply an OR operation followed by a NOT operation. The NOR gate is obtained by coupling the output of the OR gate with the NOT gate. Thus, for the same combination of inputs, the output of a NOR gate will be opposite to that of an OR gate. Its Boolean expression is X = A + B\. It is read as X equals A OR B NOT.
