 Suman Shrama Scobacs said: (Feb 14, 2012) NAND gate is a combinatioin of AND GATE + NOT GATE. if both inputs is 1 then for AND gate Output is 1*1=1 and NOT of 1=0.

 Shewangizaw Bogale said: (Feb 26, 2017) OR gate : is a Boolean operator that gives the value 1 if at least one operand has a value of 1. Example : 1 OR 1 = 1 OR 0 = 0 OR 1 = 1 (one). AND gate : is a Boolean operator that gives the value 1 if and only if all the operands are 1, and otherwise has a value of zero. 1 AND 1 = 1. NOT gate : is a Boolean operator with only one variable that has the value one when the variable is zero and vice versa. 1 NOT = 0, 0 NOT = 1. NOR gate : a Boolean operator that gives the value, only when all operands have a 0 value. Example : 0 NOR 0 = 1. NAND gate : is a combination of the result of AND GATE, and then using a NOT gate. Example : 1 NAND 1 = 0.

 Banjara said: (Aug 14, 2019) In NOR also the output will be 0, if both inputs are 1, NOR = OR+NOT. OR Gate:- 0-0 = 0 0-1 = 1 1-0 = 1 1-1 = 1 So, 1 NOR 1 = 0 also.
