Difference between AND gate and OR gate

Difference between AND gate and OR gate

In electronics logic gates plays an important role in boolean algebra and also logic gates are the basic building blocks of electronic circuits to design digital circuit. In boolean algebra we performs logic operations in digital circuit on inputs and then we will get the output. AND gate and OR gate both are the logic gates. In simple words AND gate performs multiplication and it is denoted by ‘•’ and OR gate performs addition and it is denoted by ‘ + ‘ . A logic gate which performs logical multiplication of binary input is know as AND gate. A logic gate which performs logical multiplication of binary input is know as OR gate. The difference between them is as follows

                     AND gate                    OR gate
1) A logic gate which performs logical multiplication of binary input is know as AND gate.

2) The boolean expression for AND gate is A • B.

3) The output of AND gate is high or 1 when both the inputs are high or one.

4) The AND gate follows the rule of conjunction.

5) The truth table for AND gate is:

      A       B       C
     0      0 0
    0      1 0
    1     0 0
    1      1 1

 

6) The symbol for AND gate is :

1) A logic gate which performs logica addition of binary input is know as OR gate.

2) The boolean expression for OR gate is A + B.

3) The output of OR gate is high or 1 when any one input is high or 1.

4) The OR gate follows the rule of disjunction.

 

5) The truth table for OR gate is:

      A        B       C
0 0 0
0 1 1
1 0 1
1 1 1

 

6) The symbol for OR gate is :
