$).$ Consider the two $16-$bit words $($shown in binary$)$ below. Recall that to compute the Internet checksum of a set of $16-$bit words, we compute the one's complement sum of the two words. That is$,$ we add the two numbers together, making sure that any carry into the $17$th bit of this initial sum is added back into the $1\text{'}$s place of the resulting sum$)$; we then take the one's complement of the result. Compute the Internet checksum value for these two $16-$bit words:

$1010110001101001$this binary number is $44137$ decimal $($base $10)$

$1101011000000100$this binary number is $54788$ decimal $($base $10)$

$$

$(1)$ What is the sum of these two $16$ bit numbers $(5$pt$)?$

$$

$$

$$

$(2)$ Using the sum from Part $1,$ what is the checksum $(6$pt$)?$
