(N/A) Basic gates are the fundamental building blocks of digital logic circuits. They perform simple logical operations. The three basic logic gates are:
$1$. $NOT$ gate: It acts as an inverter,producing an output that is the inverse of the input.
$2$. $AND$ gate: It produces a high output $(1)$ only if all its inputs are high $(1)$.
$3$. $OR$ gate: It produces a high output $(1)$ if at least one of its inputs is high $(1)$.
Universal gates are logic gates that can be used to implement any Boolean function or construct any other type of logic gate without the need for other types of gates. The two universal gates are:
$1$. $NAND$ gate: It is a combination of an $AND$ gate followed by a $NOT$ gate.
$2$. $NOR$ gate: It is a combination of an $OR$ gate followed by a $NOT$ gate.

$A$	$B$	$X$
$0$	$0$	$0$
$0$	$1$	$1$
$1$	$0$	$1$
$1$	$1$	$1$
