Logic gates are physical devices or idealized models that implement Boolean functions. They perform logical operations on one or more binary inputs and produce a single binary output. These operations are the basis for all digital computation, from simple calculators to advanced microprocessors.
The NAND (Not-AND) gate is the inverse of the AND gate. It outputs a 0 only when all inputs are 1. Because any logical function can be created using only NAND gates, it is known as a "Universal Gate."
There are seven basic types of logic gates used in digital systems. logic gates pdf notes download
Logic gates are combined to form complex circuits like adders, multiplexers, and memory units. Understanding how to read schematic symbols and interpret truth tables is the first step toward mastering digital logic design.
The XNOR gate is the inverse of the XOR gate. It outputs a 1 only when the inputs are the same (both 0 or both 1). Logic gates are physical devices or idealized models

The OR gate produces a high output if at least one of its inputs is high. It only outputs 0 when all inputs are 0. The NAND (Not-AND) gate is the inverse of the AND gate
A truth table is a mathematical table used to show the output of a logic gate for every possible combination of inputs. In digital logic:0 represents "Low," "Off," or "False."1 represents "High," "On," or "True."
