Because you can build any other type of gate from them.
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.
Both are universal gates.
Nand and nor gates are called universal gates .they called so as since any logic function can be done with nand and nor gates
There are 2 types of universal gates in physics: the NAND gate (combinations of NAND gates can produce any logic function) and the NOR gate (combinations of NOR gates can also produce any logic function). These gates are considered universal because they can be used to implement any logical function.
NAND and NOR
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
Seven gates, they are: not, and, or, nor, nand, xor, xnor.
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.
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
No, XOR gate is a not a universal gate. There are basically two universal gates NAND and NOR.
A universal gate is a logic gate that can be used to implement any logic function. The NAND gate and NOR gate are examples of universal gates because any other logic gate can be constructed using only NAND or only NOR gates.
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.
