logic gates and truth tables

There are total 4 logic gates

1. NAND
2. NOR
3. XOR 
4. XNOR

NAND

In computerized gadgets, a NAND entryway (NOT-AND) is a rationale door which delivers a yield which is false just if every one of its sources of info are valid; therefore its yield is supplement to that of an AND entryway.

NOR

A NOR entryway is a computerized rationale door that gives a yield of 0 when any of its sources of info are 1, generally 1. NOR doors can be made to deliver an assortment of rationale entryways, including OR AND entryways. The yield of the NOR entryway is a rationale 0 as long as the information voltage is beneath the edge.

XOR

The XOR entryway (once in a while EOR door, or EXOR entryway and articulated as Exclusive OR entryway) is an advanced rationale door that gives a genuine (1 or HIGH) yield when the quantity of genuine data sources is odd. A XOR door executes an elite or; that is, a genuine yield comes about in the event that one, and just a single, of the contributions to the entryway is valid.

XNOR

A XNOR entryway (once in a while alluded to by its expanded name, Exclusive NOR door) is a computerized rationale door with at least two information sources and one yield that performs intelligent fairness. The yield of a XNOR door is genuine when the greater part of its sources of info are valid or when the majority of its data sources are false
