## LOGIC GATE

Logic gate is two output conditions devices have two conditions namely, specifying zero volts output logic 0 (low) and 5 volt output stating logic 1 (high). Logic gate can be used to perform specific functions, such as AND, OR, NAND, NOR, NOT, or XOR. Symbols shown in the image below standard logic gates for ISO.

**AND Gate**

AND Gate is used to produce a logic 1 if all inputs have a logic 1, if not then be generated logic zero.

**NAND Gate**

NAND Gate will have a 0 when all the logic input is 1. On the other hand, if there is logic 0 at the input NAND gate, the output will be worth 1.

**OR Gate**

OR Gatewill give output 1 if one of the inputs at state 1. If the desired output 0, then all entries must be in a state of zero.

**NOR Gate**

Gate NOR will provide output 0 if one of the inputs at state 1. If the desired output 1, then all entries must be in a state of zero.

**NOT Gate**

NOT Gate is a portal that serves as an inverting input (inverter). If the input is high then the output is low, and vice versa.

**XOR Gate**

XOR Gate will provide input-output 1 if the inputs have different conditions.
