They are called universal gates because all of the other gates may be constructed using only those two gates. That is important because it's a lot cheaper in practice to make lots of similar things than a bunch of different things (different gates). Simple, huh?

NAND AND NOR gates are called universal gates because they can be used to create all the remaining logical gates. like sending the same input to the inputs of the NAND or NOR will make it a NOT gate.

NAND and NOR gates are called universal gates because they can be used in place of all basic gates that AND ,OR and NOT. They are inexpensive to make and they can be used to make any circuit thoughcan use only one type of universal gate to make any circuit. Gates are mainly switches which can be used to decide the output of any input.They can be used to get desired results by givin inputs.

Because with a combination NAND and NOR gates alone, it's possible to create all other logic gates like AND, OR, XOR etc and you can design any logic circuit.

All other gates/functions can be implemented by NOR or NAND gates. so they are called universal gates. In fact, in chips, entire logic maybe built using only NAND (or NOR) gates.
eg: inverter-- nand with inputs shorted.
and ------ nand followed by a inverter(using nand).
or--------- giving inverted inputs to nand gate.
If you delve deep into realms of VLSI you maybe able to understand the reason .Implementing with NAND is easier when considering power and area of the chip.

You can make any other gate using nand and nor.

Any other gate i.e. AND, OR, XOR etc can be created using these basic gates. I.e. you need only nand and nor gates to create logical CIRCUITS!!!

They r called universal gates as they can be used 2 design all other logic circuit elements like XOR,NOR,etc.
also these gates can be realized through easy combination of diodes thus making them easy 2 use base elements in any chip designing project.

cuz , from them you can create any other one!
