AND

An AND gate can have two or more inputs. The output of an ANDgate is true when all its inputs are true.NAND

A NAND gate can have two or more inputs. The 'o' on the outputmeans 'not' showing that it is a Not AND gate. The output of aNAND gate is true unless all its inputs are true.OR

An OR gate can have two or more inputs. The output of an ORgate is true when at least one of its inputs is true.NOR

A NOR gate can have two or more inputs. The 'o' on the outputmeans 'not' showing that it is a Not OR gate. The output of a NORgate is true when none of its inputs are true.EX-OR

An EX-OR gate can only have two inputs. The output of an EX-ORgate is true when its inputs are different (one true, one false).EX-NOR

An EX-NOR gate can only have two inputs. The 'o' on the outputmeans 'not' showing that it is a Not EX-OR gate. The output of anEX-NOR gate is true when its inputs are the same (both true or both false).
