This question really needs a little more context, but an attempt would be:
1: Properties common to both NAND and NOR gates:
- they are both electronic logic circuits (as implied by the term "Gate")
- they both compute a primitive single valued Boolean function of two or more input terms
- they both implement the inverted output version of their primitive (the leading 'N')
- there are no families of logic components that implement one and not the other in their catalog
2: differences:
- the NAND output is TRUE iff any of its inputs are FALSE
- the NOR output is FALSE iff any of its inputs are TRUE
- the NAND circuit is much simpler to implement than NOR
(NB: the term 'iff' means 'if and only if' - it is not a typo)

What are the advantages of nand gate?
because it is an universal gate that control and repairs other gates.

What are the advantages of universal logic gates?
THE MAIN ADVANTAGE OF THE UNIVERSAL LOGIC GATES IS THAT IT CAN BE USED TO MADE ANT KIND OF LOGIC GATE .......BY USING IT . NAND AND NOR ARE CALLED AS UNIVERSAL GATES ARE USED TO MAKE ANY GAATES AS OR ,AND, XNOR,NOT. logic gates are used in many everyday electronic devices such as tv's, computers and telephones.

Difference between Nor and Nand gate flip flops?
NAND is Not AND, meaning that if both inputs are true, the output is false.Any other combination (Including 0 0) does not change the output and it remains true. It's the opposite of AND, in which both inputs must be true for the output to be true.NOR is Not OR. If at least one input is true, the output will be false.It's the opposite of OR, where the output is true if at least one input is true.The main difference is that NOR requires at least oneinput being true to make the output false, where NAND requires both to be true.
Which is the universal gate nand or nor?
Both are universal gates.
Is xor gate is a universal gate?
No, XOR gate is a not a universal gate. There are basically two universal gates NAND and NOR.
What is universal gates?
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
What is universal logic gate?
universal logic gate is a gate using which you can make all the logic gates there are two such gates NOR gate and NAND gate
An example of a universal building block is?
NAND and NOR gate
What is the definition of universal gate?
universal gates are the ones from which we can design other gates also. for eg. NAND and NOR gates. they help in forming the uniformity in the circuits.
Universal properties of NAND and NOR gate with logic diagram?
NAND gate is nothing but a AND gate with a NEGATION at its output. Its truth table is INPUT1 INPUT2 OUTPUT 0 0 1 0 1 1 1 0 1 1 1 0
How nand gate acts as a universal gate?
A universal gate is a gate which can implement any Boolean function without need touse any other gate type.The NAND and NOR gates are universal gates.In practice, this is advantageous since NAND and NOR gates are economical andeasier to fabricate and are the basic gates used in all IC digital logic families.In fact, an AND gate is typically implemented as a NAND gate followed by aninverter not the other way around!!Likewise, an OR gate is typically implemented as a NOR gate followed by an inverternot the other way around!!A universal gate is a gate which can implement any Boolean function without need touse any other gate type.The NAND and NOR gates are universal gates.In practice, this is advantageous since NAND and NOR gates are economical andeasier to fabricate and are the basic gates used in all IC digital logic families.In fact, an AND gate is typically implemented as a NAND gate followed by aninverter not the other way around!!Likewise, an OR gate is typically implemented as a NOR gate followed by an inverternot the other way around!!can be combined to produce AND, OR,NOT,XORand XNOR gates
Why NOR gate is called universal gate?
That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.
Symbol of universal gate?
The two categories for logic gates are basic logic gates and universal gates. Gates are identified by their function and universal gates are identified as NAND gate or NOR gate.
Define universal gate?
A logic circuit of any complexity can be realized by using only the three basic gates (NOT, AND, and OR Gates). There are two universal gates, the NAND Gate and the NOR gate. Each of those can also realize logic circuit single-handedly. The NAND and NOR gates are therefore called universal gates.
Why are NAND and NOR gates known as universal gates?
Because you can build any other type of gate from them.
