The nand gate is prefered over the nor gate because for a nand gate, all other states are true except the 1 1 state which is false while for a nor gate all other states are false except the 0 0 state which is true.

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
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 gates are preferred to NAND gates in program logic array systems when implemented as an ic?
electron mobility in nand 3 times more tat of nor gate. This makes nand faster than nor.
Difference between Sr flip-flop nand gate and Sr flip-flop nor gate?
The nand gate variety of the SR flip-flop uses falsevalues to change state with, while the nor gate variety of the SR flip-flop uses true values to change state with.
The OR gate can be converted to the NAND function by adding----gate to the input of the OR gate?

How many minimum NOR gates is required to implement NAND gate?
A 2 input NAND gate requires 4 NOR gates.A 3 input NAND gate requires 5 NOR gates.A 4 input NAND gate requires 6 NOR gates.etc.
Why nand gate is preferred when compared to nor gate?
b'coz t mobility of electrons in NAND gate is 3 times higher than that of NOR gate
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.
Which is the universal gate nand or nor?
Both are universal gates.
An example of a universal building block is?
NAND and NOR gate
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
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.
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.
How does a nor gate work?
A series of NAND gates tied together.
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.
