The XOR (Exclusive Or) gate has a true output when the two inputs are different. When one input is true, the output is the inversion of the other. When one input is false, the output is the non-inversion of the other.

0 0 0
0 1 1
1 0 1
1 1 0
Look at the last two lines. You see that R is NOT B, but only when A is true. The same can be said of A; R is NOT A, but only when B is true.
Yes._____A----|_____NOR------QThis is an inverter.

1 gate.
You can't make XOR out of NOT alone. Mathematically, NOT takes only a single argument, and its gate, an inverter, takes a single input. There's no way to combine two inputs giving a single output with one input gates. You need some two input gates to do the job. They can be AND, OR, NAND, NOR, or some combination, but you need something. That said, they don't have to be IC gates; you can combine two inputs with diodes to make an OR gate, so you could make XOR with only inverters and diodes, i.e. no other gate symbols on your schematic, but it would mot be making XOR out of NOT.
yes
the easiest way to make an xnor gate is with a 7486 (or equivalent) integrated circuit, a quad xor gate. connect the output of one gate to one in put of another gate. connect the other input of the second gate to Vcc. the second xor gate will then act as an inverter.
XOR
xor and xnor gates are derived from not gate
yes... xor is derived gate from primary gates
No, XOR gate is a not a universal gate. There are basically two universal gates NAND and NOR.

The out put of the xor gate is o when the input is 111 because of the inverter at the output of the or gate.A2XOR = Exclusive Or gate. This means that the output is only 'true', when only 1 of the inputs is 'true'. The exclusivity means that if another input is true, then the output stays 'false'. It will only switch on when only one input is on.
For 2-input EX-OR gate, if one input is A, the other input is B, and the output is Y. Then the Boolean expression for EX-OR (XOR) function (gate) is Y=A⊕B The output Y is true if either input A or if input B is true, but not both.Y= ( (A and NOT B) or (NOT A and B) ) ;
its not
XOR (Exclusive OR) gate is exclusively for either. OR allows 10, 01, 11. XOR allows 10 or 01, but not 11.
