2. LOGIC GATES
 Logic gates are the basic building blocks of any digital system.
 It is an electronic circuit having one or more than one input and only one output.
 The relationship between the input and the output is based on a certain logic.
 Based on this, logic gates are named as AND gate, OR gate, NOT gate etc.

3.  It performs the operation of inversion or complementation.
 That is why it is also known as invertor. It changes a logic level to its opposite level.
i.e.it changes 1 to 0 and 0 to 1.
NOT GATES

4. AND GATE
 The AND gate has two inputs marked as A and B and output as Y.
 The AND gate represents the Boolean equation Y = A.B
 From the above circuit it is clear that AND gates give an output only when both the
switches A and B are closed. It means that the both A & B are at 1, the output will also at 1.
 For all other combinations of the values A and B output is zero

5. OR GATE
 The OR gate has two inputs marked as A and B and output as Y.
 Now A ,B and Y can have one of the two states either 0 or 1.
 The OR gate represents the Boolean equation Y=A+B .
 The OR gate has output 1 and either A or B or both A & B are at logic 1.
 Above circuit shows that the lamp will light up when either switch A and B or both A & B are
closed.
 The output will be zero if and only if both the inputs or at logic zero.
 It means that lamp remain off when only when both the switches A and B are open.
