## What is gate explain?

Advertisements. Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic. Based on this, logic gates are named as AND gate, OR gate, NOT gate etc.

## What is gate and its types?

The basic logic gates are classified into seven types: AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate. All the logic gates have two inputs except the NOT gate, which has only one input. When drawing a truth table, the binary values 0 and 1 are used.

**What are gates in computer?**

“In a computer, a gate controls the flow of electric current through a circuit. The gate consists of transistors; the transistors are selected by the chip designer from two basic types (PMOS and NMOS transistors) that are found in the ubiquitous CMOS (complementary metal-oxide semiconductor) technology.

### What are basic gates?

All digital systems can be constructed by only three basic logic gates. These basic gates are called the AND gate, the OR gate, and the NOT gate. Some textbooks also include the NAND gate, the NOR gate and the EOR gate as the members of the family of basic logic gates.

### What is use of NOT gate?

A NOT gate, often called an inverter, is a nice digital logic gate to start with because it has only a single input with simple behavior. A NOT gate performs logical negation on its input. In other words, if the input is true, then the output will be false. The truth table for a NOT gate appears to the right.

**How many types of gates are there?**

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.

## What is the function of OR gate?

The function of an OR gate is to find the maximum between the inputs which are binary in nature. It is one of the basic gates used in Boolean algebra and electronic circuits like transistor-transistor logic, and complementary metal-oxide semiconductors make use of it.

## Why gates are used in computer system?

Computers need a way to manipulate those 1s and 0s, so that they can eventually do more complicated operations like calculating the 50th digit of π. 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.

**What is the truth table of OR gate?**

Truth table is a table which shows the shows the output state depending upon the possible combination of input states.It shows the function of a logic gate. OR Gate: An OR Gate is an electronic circuit that gives a true output (1) if one or more of its input are true. (+) is used to show the OR operation.

### What are the applications of gates?

The applications of Logic Gates are:

- NAND Gates are used in Burglar alarms and buzzers.
- They are basically used in circuits involving computation and processing.
- They are also used in push button switches.
- They are used in the functioning of street lights.
- AND Gates are used to enable/inhibit the data transfer function.

### What is the function of NOT gate?

A NOT gate performs logical negation on its input. In other words, if the input is true, then the output will be false. Similarly, a false input results in a true output. The truth table for a NOT gate appears to the right.

**What are the applications of ex OR gate?**

There are many applications for XOR gate such as:

- Arithmetic Operations:
- Parity Checker:
- Controlled Inverter:
- Binary to Gray / Gray to Binary Conversion:
- Combinational Logic Circuit Minimization:
- Digital Comparator:
