basic gate

  NOR Gate is created by applying NOT operation to an OR gate. Hence, the outputs of this gate are opposite to that of OR gate when the inputs are kept same.[[wysiwyg_imageupload::]] Logic gate consists of three basic logic gates namely NOT, AND and OR. Each of them performs a different logic function. NOT gate is a logic element whose output stage is always the complement of the input stage means when you supply logic 1 we will logic 0 and vice versa. The operation of AND gate is such that output of gate is binary 1 if and only if all input are binary 1. If any of the input is binary 0 we will receive output as binary 0. OR gate is another basic logic gate like AND gate it as two input and one output.  

 NAND Gate is created by applying NOT operation to an AND gate. Hence, the outputs of this gate are opposite to that of AND gate when the inputs are kept [[wysiwyg_imageupload::]]same. NOT gate is a logic element whose output stage is always the complement of the input stage means when you supply logic 1 we will logic 0 and vice versa. The operation of AND gate is such that output of gate is binary 1 if and only if all input are binary 1. If any of the input is binary 0 we will receive output as binary 0. OR gate is another basic logic gate like AND gate it as two input and one output. The operation of gate is such that output of gate is binary 1 if any of the input is binary low and we will receive logic zero only when both the inputs are low.
