# What is the difference between AND and OR logic gates?

## What is the difference between AND and OR logic gates?

However, the two are mainly differentiated on the basis of logic operation performed by them. The crucial difference between AND gate and OR gate is that AND gate performs multiplication of the digital inputs. As against the OR logic gate is used to execute the addition of the digital inputs.

What is the combination of NOT and OR gate?

NAND gate
The combination of an AND gate and a NOT gate is called a NAND gate, as shown in the diagram.

WHAT IS AND OR invert gate?

AOI also known as AND-OR-Inverter. AND-OR-Invert (AOI) logic or say gates are two-level logic functions constructed from the combination of one or more AND gates followed by a NOR gate. If we construct AND, OR and NOT gate separately, Number of transistor in AOI gates are less.

### What are the differences between AND gate OR gate and not gate?

1. AND gate gives a ‘true’ output only when both inputs are ‘true’, whereas OR gate gives an output of ‘true’ if at least one of the inputs is ‘true’.

WHAT IS AND or OR logical gate explain briefly?

The OR gate gets its name from the fact that it behaves after the fashion of the logical inclusive “or.” The output is “true” if either or both of the inputs are “true.” If both inputs are “false,” then the output is “false.” In other words, for the output to be 1, at least input one OR two must be 1. OR gate. Input 1.

What does an OR gate do?

The OR gate is a digital logic gate that implements logical disjunction (∨) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results.

#### How many logic gates are in a CPU?

There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR. The AND gate is so named because, if 0 is called “false” and 1 is called “true,” the gate acts in the same way as the logical “and” operator.

Which logic gate is a combination of OR and NOT gate?

NOR gate
The NAND gate operates as an AND gate followed by a NOT gate. It acts in the manner of the logical operation “and” followed by negation. The output is “false” if both inputs are “true.” Otherwise, the output is “true.” The NOR gate is a combination OR gate followed by an inverter.

WHAT IS AND gate OR gate and NOT gate?

The OR gate is an electronic circuit that gives a high output (1) if one or more of its inputs are high. The NOT gate is an electronic circuit that produces an inverted version of the input at its output. It is also known as an inverter.

## What is positive and negative logic?

Positive logic is defined as a high voltage level representing a logic 1 and a low voltage level representing a logic 0. Negative logic is the reverse, i.e., a low voltage level represents a logic 1 and a high voltage level represents a logic 0.

Can both OR and AND gates can have only two inputs?

Both OR and AND gates can have only two inputs. Explanation: Any number of inputs are possible.
