01․ In the boolean algebra, a variable has ________ different state(s)/value(s).
Boolean Algebra is based on binary number system which has two different states either 1 or 0.
02․ In Boolean algebra A.A is equal to
In Boolean algebra, A.A = A, where A is a variable having value either 1 or 0.
03․ AND operation is equivalant to
Logical AND operation means Y = A.B i.e. A AND B = A Intersection B. It results in 1, if and only if all the inputs are 1.
04․ OR operation is equivalant to
Logical OR operation means A OR B = A Union B (Y = A + B). It results in 1, if at least one input is 1.
05․ In Boolean algebra AND is represented by
In Boolean algebra, logical AND is represented by ×, A AND B = A × B.
06․ In Boolean algebra, OR is represented by
In Boolean algebra logical OR is represented by +, A OR B = A + B.
07․ X + X.Y = ?
By applying Absorption property in Boolean algebra, 
.
.08․ LSI means
LSI means Large Scale Integration.
The abstraction level of the Integrated circuits are characterized as
- Small Scale Integration
- Medium Scale Integration
- Large Scale Integration
- Very Large Scale Integration
09․ Truth table is used to express
Truth tables are used to express the Boolean expression. It has 2n no of outputs for n no of inputs. It means for two inputs there is 22 i.e. 4 outputs.
10․ Complement of NOR and OR gate is ________ and ________ respectively.
OR is the complement of NOR and reverse logic is also true.
