The 2-bit adder has two input lines and two output lines.
The two input lines are the two bits to be added, call them "Bit-A" and "Bit-B".
The two output lines are "sum" and "carry".
Here are the states of the "sum" and "carry" outputs, for every combination of inputs "Bit-A" and "Bit-B":
Bit-A . . . Bit-B . . . Sum . . . Carry
0 . . . . . . . . 0 . . . . . . 0 . . . . . . 0
0 . . . . . . . . 1 . . . . . . 1 . . . . . . 0
1 . . . . . . . . 0 . . . . . . 1 . . . . . . 0
1 . . . . . . . . 1 . . . . . . 0 . . . . . . 1
The Boolean functions for the two output lines are:
SUM = [ (Bit-A) XOR (Bit-B) ]
CARRY = [ (Bit-A) AND (Bit-B) ]
(Actually, I think the "adder" only has one output line, called "sum"; if it also has the "carry" output,
then it's called a "full adder". To me, a full adder is a snake plus a dead frog.)

When you add 1011 1101 in the binary system you obtain?
When you add 1011 and 1101 in the binary system, you get 11000. To calculate this, start by adding the rightmost digits, which are 1+1=10 in binary (0 carry 1). Then, move to the left, adding the next digits along with any carries until you reach the leftmost digit. The result is 11000 in binary.
Why full adder is better then half adder?
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
How many digits are in the binary system and what are they?
The binary system uses two digits, zero and one.

What is equal to binary digits?
Binary digits are 'bits'. There are only two of them. It doesn't matter what you call your digits or how you write them, as long as you do all of your binary arithmetic with only two symbols.
What is does binary mean?

Define half adder and full adder?
From wikipedia: A half adder is a logical circuit that performs an addition operation on two binary digits. The half adder produces a sum and a carry value which are both binary digits. A full adder is a logical circuit that performs an addition operation on three binary digits. The full adder produces a sum and carry value, which are both binary digits. It can be combined with other full adders or work on its own.
How many digits are used in a binary number system and what are they?
