AND gate – Wikipedia
The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – AND gate behaves according to the truth table. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If not all inputs to the AND gate are HIGH, LOW output results.

AND Gate: What is it? (Working Principle & Circuit Diagram)
In other words, an AND gate is a digital device that produces high output only when all inputs are high and produces low output under all other inputs conditions. A high digital signal means logically 1 and a low digital signal means logically 0. An AND gate may have any number of input probes but only one output probe. 2 Input AND

[3] In reversible logic, Toffoli or Fredkin gates are used. Electronic gates A functionally complete logic system may be composed of relays, valves (vacuum tubes), or transistors. The simplest family of logic gates uses bipolar transistors, and is called resistor-transistor logic (RTL).

logic gate (AND, OR, XOR, NOT, NAND, NOR and XNOR) – TechTarget
A logic gate is a device that acts as a building block for digital circuits. They perform basic logical functions that are fundamental to digital circuits. Most electronic devices we use today will have some form of logic gates in them. For example, logic gates can be used in technologies such as smartphones, tablets or within memory devices.

How do logic gates work? – Explain that Stuff
18 mai 2023An OR logic gate works this way with two electrical inputs. If either input is switched on (that is, carries a number 1), the output will be 1 as well. Otherwise the output will be 0. In electronics, we represent an OR gate with a different symbol. Three ways in which it can work are shown beneath:

How Logic Gates Work: OR, AND, XOR, NOR, NAND, XNOR, and NOT – How-To Geek
As in each of the first three cases, a full AND (which would be true and true) isn’t present. Hence, the outcome is true ( 1 ). For the last input, true and true, a full AND is present and thus (due to the NOT component, the N in NAND ), the outcome is false. In this image, we see an SN7400N chip that has four logic , namely, NAND .

Why are NAND gates used to make AND gates in computers?
CMOS logic can be very easily used to make possibly any circuit with very few number of transistors, consuming low power, and for operation at high speeds. As such, making a part of the circuit as NMOS (with resistive load) is very cumbersome and inefficient. So a NAND gate followed by a inverter is used to design an AND .

Computers use logic gates to transform the 1s and 0s from input wires. A logic gate accepts inputs and then outputs a result based on their state. NOT gate The simplest gate is the NOT gate, also known as an inverter. It accepts a single input and outputs the opposite value. If the input is 0 , the output is 1 :

Logic Gates. Logic gates are devices that implement Boolean functions, i.e. it does a logic operation on one or more bits of input and gives a bit as an output. They are the basic building blocks of any digital system. It is an electronic circuit having one or more inputs and only one output. The relationship between the input and output is …
